Perkin Elmer was a leading supplier of sputter deposition equipment in the 1990s. Their 4400 and 2400 series sputtering systems were used for semiconductor manufacturing and development, as well as applications like thin film recording heads and optical coatings. The systems provided high quality deposition with flexibility, reliability, and clean vacuum environments. They represented an integrated solution for critical processes in VLSI production from mask making through sputter deposition.
BWE Ltd, formerly Babcock Wire Equipment Ltd, has operated from its Ashford headquarters in the Southeast of England since 1969, when the company first produced cold welding machines. Conform™ machines have been manufactured since 1976 when they were initially used for extruding round wire. Continuous development aimed at extending the capabilities of the Conform process led to an
increasing number of applications including magnet wire, electrical conductors, refrigeration tube and ultimately, in 1984, the introduction of the Conklad™ process for aluminium clad steel wire and CATV and fibre optic cables.

Perkin elmer series 4400 and 2400 sputter deposition systems
1. Please contact us by sales@perkin-elmer-sputter.com for more information on any Sputtering Deposition
As new commercial and industrial technologies emerged and grew, so did the use of
sputtering as a technique for deposition thin films of desired characteristics. The Perkin
Elmer 4400 and 2400 Series sputtering systems were designed to meet the changes of this
changing technical environment, whether in development or production.
With an installed base of more than thousands of systems, Perkin-Elmer was a leading
supplier of sputter deposition equipment for high technology application in 1990's. The
Perkin Elmer 2400 Series sputtering systems were used not only in the production of
semiconductor devices but also in the development and manufacturing of thin film
recording heads, thin film resistors and capacitors, optical coatings, gallium arsenide
lasers and fiber optics.
Quality, performance and stability backed by more than two decades of experience in
vacuum technology and UHV design were built into every Perkin Elmer sputtering
system. The 4400 and 2400 Series were designed for flexibility offering a wide range of
operating and process modes. The highest quality construction and components assure
reliable operation and an ultra clean vacuum environment to yield consistently
reproducible results. Every Perkin Elmer sputtering system was supported by years of
technological experience and backed by a worldwide sales and service organization
dedicated to prompt courteous service.
The 4400 and 2400 Series of sputtering systems represent just one part of the Perkin
Elmer Semiconductor Equipment Group's unique "one source" approach to cost-effective
VLSI production. From mask making to photolithography, dry etching and sputtering
deposition, the Semiconductor Equipment Group provides an integrated line of
performance-proven production equipment specially designed to address each critical
process. This "one source" solutions designed to meet the semiconductor industry's
demands throughout the 1980's.
Versatile Systems For Any Sputtering Need
The 4400 Series, designed specially for high throughput production environments,
features a high capacity load lock and a broad range of operating models to accommodate
virtually any thin film coating requirement.
High Throughput
The 4400 Series fast cycle load lock, cryogenic pump, and full flood Meissner trap
ensures quick turnaround on batch loads. High throughput are achieved for a full range of
substrate sizes and shapes.
High Yield
A rotating substrate table for multi-pass deposition helps assure high uniformity and run-
to-run repeatability. Simplicity of mechanical design with a minimum number of moving
parts in the process chamber minimizes the generation of defect-causing. Easy loading
pallet designs reduce wafer breakage. Consistently clean vacuum conditions assure
reproducible high quality films.
Optimum Process Control
The 4400 Series provides a broad choice of target materials, machine operating models,
pressure and gas controls, cathode configurations and power levels. Operating models
include DC magnetron, RF magnetron, RF diode, bias sputter, reactive sputter, co-sputter
and RF etch.
Total Control of Critical Film Characteristics
The 4400 Series systems yield excellent films for a wide variety of materials including
aluminum alloys, platinum silicide, titanium-tungsten, nichrome-gold, silicon nitride,
silicon dioxide, precious metals and permalloy.

Deposition Of Thin Film for VLSI Geometries
4400 Series System configurations
No single cathode design can effectively meet the varied needs of different users or even
the possible multiple needs of one user. Every film requires an optimum combination of
target material, size, and shape for its most efficient fabrication. Recognizing these
realities, the 4400 Series provides two distinct cathode configurations: 8" circular and
delta-shaped.
4400
A general purpose sputtering system employing up to three 8" diameter circular cathodes
in DC magnetron, RF magnetron, or RF diode configurations. Power options are
available up to 2 kw RF and 5 kw DC.
4410
A delta target sputtering system designed for high rate deposition of metals and metal
alloys. The 4410 is also adaptable to the deposition of dielectrics and employs up to three
delta-shaped cathodes in DC magnetron, RF magnetron, or RF diode configuration.
Power options are available up to 3 kw RF and 10 KW DC.
4450
A delta target sputtering system, similar to the Model 4410 with load lock pumping and
heating incorporated as standard features.
4480
A delta target sputtering system of identical design to Model 4450 but including cassette-
to-cassette loading as a standard feature.
As VLSI geometries routinely approach the one to two micron region, new problems
arise in thin film deposition technology, dry etched vertical walls, deep vias and multiple
level structures must all be uniformly covered with no microcracks or cusping. Film
deposition systems must be able to provide uniform conformal coverage of these tightly
packed structures to minimize interconnect resistances and maximize yields.
Substrate heating has improved step coverage of LSI structures by increasing the surface
mobility of the depositing atoms. Additional techniques are now being used to further
enhance coverage of planar-magnetron-sputtered films. Perkin Elmer 4400 and 2400
Series sputtering systems utilize "multi-pass" design and RF bias to maximize film
coverage of VLSI structures.
As geometrical features get smaller, new materials will be employed. Metallization layers
now include the use of diffusion barriers and low resistance gate and interconnect
materials such as refractory metal silicides.
Substrate Motion
By utilizing rotating substrate table, Perkin Elmer sputtering systems allow wafers to be
coated by multiple passes through the target region. This technique can minimize
shadowing effects sometimes encountered in the single pass mode or center-to-edge
effects found in static deposition systems, while maximizing target material utilization,
step coverage and device yield.
RF Bias
The application of RF bias to the substrate re-sputters deposited material from horizontal
surfaces onto the surrounding vertical walls of the wafer. Step coverage of 50% or more
can be achieved on vertical steps and deep vias can be uniformity covered with RF bias
and multi-pass technologies.

Co-sputtering
The deposition of contamination-free, low-resistance refractory metal silicides request the
use of the purest materials. Co-sputtering provides the optimum method for depositing
these films from pure elemental targets, wile providing a convenient means to control the
stoichiometry of the films. Oxygen and carbon contamination and target-to-target
stoichiometric non-uniformities are minimized using dual target sputtering and multi-pass
techniques.
High Vacuum Technology for Maximum Process Control
Fast Cycle Load Lock Operation
The 4400 Series high capacity load lock system eliminates the need to break vacuum;
thereby reducing both pumpdown time and contamination of targets and internal chamber
surfaces. Transfer of a full pallet load of wafers from air to the process chamber and
pumpdown to a base pressure of 5X10-7 Torr can be accomplished in less than 3.5
minutes.
Contamination-free Cryogenic Pump
The process chamber vacuum system incorporates a contamination-free, closed cycle,
two-stage helium cryopump (turbomolecular pump optional). Under load conditions,
70oK is maintained in the first stage and less than 15oK in the second stage. This assures
efficient, rapid pumping of most atmospheric gases and reduction of partial pressures of
most unwanted gas species to acceptable levels. An ultimate vacuum of 10-6 scale can be
attained with typical pumping speeds of 1000 l/s for nitrogen, 1100 l/s for hydrogen and
4200 l/s for water vapor.
The Meissner Trap
A full flood Meissner trap mounted in the process chamber maintains an efficient
pumping speed for water vapor of 30,000 l/s during deposition or sputter etching. The
Meissner trap pumps water vapor at a maximum rate even with the high vacuum
cryopump throttled. This assures good quality films in critical processes such as the
deposition of aluminum alloys.
Substrate Degassing
The 4400 Series systems can be equipment with load lock heating and turbomolecular
pumping to degas substrates prior to processing and minimize pumpdown for critical
processes such as the deposition of aluminum alloys and other oxidizable metals. This
further reduces the partial pressure of undesirable gases such as water vapor.
Vacuum Control
All 4400 Series systems are equipped with ion and thermocouple gauges. A wide-range
gauge controller monitors and digitally displays vacuum levels from 10-11 to 200 microns
providing continuous monitoring of operating pressure. Additional thermocouples
provide inputs to the automatic pumpdown control and automatic lock control.
The Circular Cathode Systems-Model 4400
Model 4400 is designed for use in production environments or process development. Up
to three 8-inch circular cathodes and a 350oC quartz lamp heater may be installed in the
process chamber to accommodate a variety of processes. An optional RF power
sputtering network enables the RF/RF Co-deposition of two different materials. Precise
stoichiometries of graded interface may be easily achieved.

The Model 4400 is routinely used for such processes as the deposition of Cr-Co for
recording discs, Cr-Cu for backside metallization, TaSi2 for gate metallization and Si3N4
for interlayer dielectric.
Chrome-Cobalt
A precise ratio of chrome to cobalt is readily achieved with co-deposition using the RF
power splitting option, ideal film temperature in the range 170 oC-200 oC can be easily
obtained for optimum grain growth and orientation.
Chrome-Gold
The films resulting from the sputter deposition of chrome-gold are superior to those
obtained from evaporation processes, pre-etching prior to deposition removes native
oxide improving film adhesion and RF magnetron deposition results in lower thin film
temperature and less gold interdiffusion.
Tantalum Silicide
Tantalum silicide of any desired stoichiometry is easily deposited with co-sputtering
using the RF power splitting module. Annealed film resistivity of approximately 2.3
ohms per square can be obtained from a typical 2000 angstrom film of tantalum silicide.
Within further advances in process technology, the UHV design of the 4400 will enable it
to accommodate the deposition of refractory metal silicide films of even higher
resistivities.
Silicon Nitride
With RF bias deposition, silicon nitride films exhibiting low pin-whole count, good step
coverage and low stress can be readily deposited in the model 4400.
The RF Power Split Module
The two-way adjustable RF Power Split Module provides precise control of the level and
ratio of RF energy from a single RF generator to two 8" diameter cathodes
simultaneously. A total of 2 kw may be applied with power ratio adjustable between 5%
and 95%. This module is idea for use with the Model 4400 and 2400-8SA in R&D and in
low volume production applications, where precise control of alloying of film properties
is desired.

over a 6" annular width. Optional high performance Delta cathodes yield a uniformity of
+/-5% over a 73/4 inch band, allowing processing of up to 22 100mm wafers per cycle.
Standard Delta cathodes process 50-60 100mm wafers per hour while optional high
performance Delta cathodes yield throughput in excess of 80 100mm wafers per hour.
A particular advantage of a circular batch sputtering system is its adaptability to different
substrate sizes. The Model 4410 and other delta cathode systems can easily handle
substrate size up to 8 inches in diameter. Standard wafer size of 3 inch, 100mm, 125mm
and 150mm can easily be accommodated.

Resistivity
Perkin Elmer sputtering systems ensure low film resistivity by minimizing partial
pressure of oxygen and nitrogen below 1X10-7 Torr. With total system background
pressure of 5X10-7 Torr and an instantaneous deposition rate in excess of 8500
angstroms/minute, near-bulk resistivity for aluminum alloy films can be achieved.

By keeping oxygen content below, film hardness for typical 1 micron thick aluminum
silicon films can be kept below 100 kg/mm2 after annealing at 500oC, minimizing
bonding failures.
Specularity
High quality aluminum alloy films of 70-90% relative reflectance are routinely produced
in high rate DC Delta magnetron systems, yielding wafers easily accommodated in
today's projection mask aligners.
Optional load lock pumping and wafer degassing further minimize water vapor and
hydrogen, the principal contaminants that contribute to hillock growth and poor
specularity. As metallization films become thicker and specularity degrades, further
reduction of unwanted gases can be achieved through the use of supplemental hydrogen
getter pumping in the Model 4410 and other Delta cathode systems.
Step Coverage
The high rate sputtering made possible with Perkin Elmer Delta DC magnetron cathodes
produces sufficient heat to maintain film temperature in the ideal range. Heating the
substrate in this manner and re-sputtering the deposited material through RF bias
improves coverage of vertical surfaces in VLSI structures. It also minimizes cracks and
cusping.
Optional High Performance Delta Cathodes
Provide more uniform deposition over a wider annular region of the pallet. A maximum
of twenty two 100mm wafers can be loaded yielding 50% more throughput for a typical
metallization process. The HIGH THROUGHPUT option consists of a modified shaping
aperture, a high performance Delta cathode and a pallet nested for twenty two 100mm
wafers. The region of high uniformity is extended across the total 8" annular width of the
pallet. A uniformity of +/-7% is achieved across a 73/4 inch band suitable for mounting
two concentric rows of 100mm wafers. This wide brand of uniformity means that 51/4",
8", or 14" recording discs can be accommodated in the system.
The Delta Cathode Dual Deposit Sputter Module
The Delta Cathode Dual Deposition Sputter Module, operable in either a dual DC mode
or DC and RF mode, is designed for higher throughput and larger scale production.
Separate power suppliers allow independent application of either DC or RF energy to two
delta cathodes simultaneously. The dual deposit sputter module for Models 4410, 4450
and 4480 is the choice for co-sputtering of refractory metal silicides for VLSI circuits.
The dual deposit sputter modules and the co-sputtering technique allow the deposition of
contamination-free films.

Highest Quality Sputtering-
Superior Performance-
Wide Selection of options-
In a laboratory or low-volume production environment, where the high throughput levels
of the 4400 Series are not required, the 2400 Series is the ideal alternative for high quality
sputtering in a wide variety of applications.
Model 2400-8SA
The Perkin-Elmer Model 2400-8SA features a large 211/2" rotating, water cooled annular
table with a capacity of sixty-four 2", thirty 3", or thirteen 4" wafers.
Used in conjunction with a cathode shaping aperture, the rotating table permits high
uniformity. A 4" wafer vertical range of the table facilitates coating bulk substrates. As an
added feature, up to three 8" round cathodes may be specified allowing sequential
deposition from several targets or alternately, static deposition or heating from any target
position.
Power Splitting is an optional feature of the 2400-8SA system. With this feature, RF
power can be applied to two cathodes simultaneously in any desired ratio from 5 to 95%.
Combined with the continuous substrate rotation feature, an infinite number of alloy
compositions can be developed simply by varying the power division between target.
Model 2400-8L
The Model 2400-8L load lock system ensures a constant inert gas or vacuum
environment allowing rapid pumpdown to base pressure and elimination of target pre-
cleaning. High partial pressure of water vapor is no longer a problem, even in areas of
high humidity. Additional water vapor pumping is possible with an optional Meissner
Trap. By eliminating the need to break vacuum in the process chamber, the 2400-8L load
lock reduces both pumpdown time and contamination of targets and internal chamber
surfaces. Load lock pumping is provided by a mechanical pump which is shared with the
process chamber vacuum system. Load lock pumpdown and pallet transfer are
automatically controlled. Sequence and valve position are displayed on front control
panels.
A water-cooled 8" diameter substrate table rotates the pallet 360o and automatically
aligns it precisely under any one of the three targets or the etch position. Substrates can
be loaded, processed, and unloaded in minutes improving run to run yields. A full pallet
of wafers can be transferred from air to a properly maintained process chamber and
pumped down to a base pressure of 5X10-7 Torr in less than five minutes.
Series 2400-Capabilities, Features, Options
High Uniformity
Careful cathode and chamber designs mean high uniformity,. Integral copper
channels in the anode tables insure even distribution of cooling water and RF power.
High Throughput
The 2400-8SA features a 211/2" table which enables processing of large wafer batches.
The 2400-8L utilizes a smaller pallet but provides a unique load lock system to
dramatically reduce pump-down time. Either approach maximizes efficiency.
Maximum Process Control
Both 2400 Series systems offer a wide choice of target materials, machine operating
models, and gas controls with capability to perform a variety of thin film tasks.
RF Bias
The Perkin-Elmer 2400 Series RF Bias capability enables high quality films with a
variety of materials. The RF bias provides improved step coverage, controllable

intrinsic stress for metal or dielectric films, improved alloying materials and
stoichiometry, resistivity that approaches bulk values, precisely controlled film
densities and impurities and reduced argon content.
Uniform Deposition
The 2400-8SA and 2400-8L use uniformity shaping apertures to compensate for the
geometry of the cathode sputtering pattern. The rotating substrate table further
improves uniformity in the 2400-8SA. The 2400-8L utilizes a double-disk dark space
shield to eliminate edge sputtering from the cathode plate and provide exceptional
plasma confinement.
Operation Mode Selection
In all 2400 systems, the mode selector switch provides a choice of modes:sputter
deposit, bias sputter and sputter etch.
Standard RF Features
Servo-Match automatic turning maintains proper turning despite variations in target
emission, pressure or RF power. A power stabilizer holds RF power constant.
FEATURES
The 2400-8SA Rotating Table Multi-Target System
Sequential deposition from DC magnetron, RF magnetron and conventional RF
cathodes

repetitive processes. Other capabilities include: program listing, hard copy records and

THE DELTA CATHODE SYSTEM:MODEL 4410
Perkin-Elmer's Model 4410 delta cathode production sputtering system is designed for
high yield in production environments demanding maximum throughput for metal
deposition. It also provide a high level of flexibility in process control for other materials.
The 4410 uses a delta-shaped cathode that eliminate the need for a large-area uniformity-
shaping aperture. This dramatically increases throughput while maintaining high wafer-
to-wafer uniformity.
Contrasted with circular cathodes, target utilization is substantially higher. Up to 35% of
the target can be sputtered before target change, and some 60% of the sputtered material
actually reaches the substrate pallet. This results in a lower cost per wafer and less
frequent target changes. Up to three delta or 8-inch round targets may be installed for
sequential deposition of three different materials without breaking vacuum.
The 4410 employs a fast cycle load lock, two-stage cryopump and full flood Meissner
trap to maintain the process chamber at high vacuum and in a clean condition at all times.
The process chamber is fabricated of stainless steel for contamination-free performance.
A base pressure better than 5 X 10-7 Torr is achieved within 3.5 minutes from loading
substrates into the load lock. Typical cycle time, with optional load lock heating and
pumping, is 12 to 15 minutes for the deposition of 1 micron of aluminum.
System Highlights
High rate delta DC magnetron sputtering: Aluminum and aluminum alloys can be
sputter deposited at rates in excess of 1800 Å /min, with loads of thirty 3-inch or
thirteen 4-inch wafers.
High throughput operation: Automated load lock and controller sequences provide for
efficient pump-down and pallet transfer to process chamber, maximizing throughput.
High uniformity: +/-7% deposition uniformity guaranteed with water-cooled rotating

DC bias sputter, sputter etch to 2 kw, RF magnetron, RF diode, DC delta magnetron.
Ultra-clean vacuum: Cryopump and Meissner-trapped process chamber ensures
contamination-free conditions especially important for critical processes such as the
deposition of aluminum and platinum.
Designed for operator safety: Two-button operation initiates pump-down and load
sequence. Safety interlocks on DC and RF suppliers.
Easy maintenance: Removable deposition shields permits easy system cleaning.
Automatic cryopump regeneration minimized downtime and inconvenience.
Key function clearly displayed: Valve position and system status are continuously
displayed by quick-reading LEDs on front panels.
Easy wafer loading: Tweezer grooves facilitate wafer loading. Nested pallets are
optional.
A fail-safe system: Water flow switches on cathodes, matching network and vacuum
system automatically shut the system down in case of cooling system failure.
