Sofics hebistor clamps
Latch-up Immune on-chip ESD protection for High Voltage processes and applications
While high voltage interfaces are broadly used in many IC applications like motor control, power management and conversion, LCD panel drivers and automotive systems, many IC designers still lack a low leakage, costeffective and latch-up immune ESD protection clamp that can be applied across various applications.
The behavior of many of the traditional on-chip ESD clamps is tied to the process conditions, which limits the possibilities to adapt to changing specifications. Moreover, severe reliability requirements that were long requested only for industrial and automotive applications are now being transferred to consumer electronics too.
This white paper introduces a new family of ESD/EOS/IEC protection devices, called hebistor clamps that provide competitive advantage through improved yield, reduced silicon footprint and low leakage operation. The hebistor devices are developed to protect a broad set of high voltage interfaces in BCD and high voltage CMOS and are branded under the Sofics PowerQubic portfolio. Based on measurements on TSMC 0.35um 15V and TSMC 0.25um BCD 12V, 24V, 40V and 60V technology the flexibility of the novel device is demonstrated.

2010 Taiwan ESD and reliability conference
High voltage interfaces are broadly used in many IC applications like motor control, power management and conversion, LCD panel drivers and automotive systems. Because the high voltage IC's are typically used in severe applications IC designers need to protect their circuits to a steady growing list of requirements. In this paper we present an overview of the ESD, EOS and latch‐up requirements and compare the performance of different on‐chip ESD protection approaches. The paper introduces a newly developed protection device with a high holding voltage for absolute latch‐up immunity.

For the design of on‐chip ESD clamps against system level ESD stress three main challenges exist: reach a high failure current, ensure latch‐up immunity and limit transient overshoots. Bearing these in mind, high system level ESD requirements should be within reach. A novel improved high holding current SCR is introduced fulfilling all three requirements within drastically reduced silicon area.

2011 TSMC open innovation Platform
Applications like motor control, power management and conversion, LCD panel drivers and automotive systems require IC interfaces that can tolerate and drive high voltages (10V to 100V). Moreover, in most of these applications the ICs are operated in harsh environments (high temperature, high current/voltage transient disturbance), close to the boundaries of the IC technology. Further, to reduce the Bill of Materials (BOM) system makers are constantly shifting requirements that were once a system/PCB issue to the IC makers. IC makers designing high voltage applications need robust and reliable technology that can meet a growing set of requirements.
Based on TSMC’s comprehensive BCD technology platform in 0.25um and 0.18um, Sofics has developed novel EOS/ESD protection devices that can solve those needs.
This paper first presents an overview of the EOS, ESD, latch-up and other requirements that IC makers face today. Secondly the TSMC BCD technology that was used as the verification platform is touched upon. Finally analysis results and on-going product implementations are shown on 0.25um BCD and 0.18um BCD technology. The unique BCD ESD solutions are available for TSMC foundry customers at a fraction of the development cost.

Behavioral studies of surge protection componentsjournalBEEI
In our daily life, almost all the items we used, being a computer, television, lift or vehicle we drive consist of some kind of electrical or electronics component inside. The operation of these devices could be severely affected by lightning activity or electrical switching events, as there are more than 2000 thunderstorms in progress at any time resulting in 100 lightning flashes to ground per second. In practice, any device using electricity will subject to surge damages induced from the lightning or switching of heavy load. Surge protection device (SPD) is added at the power distribution panel and critical process loop to prevent damage subsequently cause plant shutdown. There are many questions raised on the SPD.

Nowadays, mobile consumer electronics devices integrate various wireless interfaces like WIFI, Bluetooth, GPRS and GPS. Various approaches exist to protect the wireless interfaces against ESD stress. In recent years, researchers have focused on so‐called 'co‐design' techniques to solve both functional and protection constraints together which requires both RF and ESD design skills. However many IC designers still prefer to work with 'plug‐n‐play' protection concepts where the ESD clamps exhibit low parasitic capacitance, low series resistance and low leakage. This paper presents measurement results of 3 different SCR based protection approaches that exhibit high Q‐factor and low and stable parasitic capacitance over a broad voltage and frequency range. The clamps are used for protection of LNA circuits in 90nm and 40nm Low Power (LP) CMOS technologies.
On chip esd protection for Internet of ThingsSofics
Many of the applications in Internet of Things require non-standard on-chip ESD protection clamps. We identified 5 reasons.
- Non-standard signal voltages
- Low leakage requirement
- Sub-systems are powered down
- Wireless interfaces
- System level protection, on the chip
Clearly, IC designers need to think about the ESD protection strategy for their IoT system. It is wise to rely on silicon proven concepts to speed up market introduction.

On-chip ESD protection clamps for advanced 40nm and 28nm CMOS technology
Despite the rising cost for IC development, EDA tools and mask sets semiconductor design companies continue to use the most advanced CMOS technology for high performance applications because benefits like lower power dissipation, increased gate density, higher speed and lower manufacturing cost per die more than compensate the higher cost.
This return on investment however only pays off for ultra high volume applications. Due to the use of sensitive elements (such as ultra thin-oxide transistors, ultra-shallow junctions, narrow and thin metal layers), increased complexity through multiple voltage domains and the use of IP blocks from various vendors, a comprehensive ESD protection strategy becomes more important.
This white paper presents on-chip ESD protection clamps and approaches for 40/28nm CMOS that provide competitive advantage by improved yield, reduced silicon footprint and enable advanced multimedia and wireless interfaces like HDMI, USB 3.0, SATA, WiFi, GPS and Bluetooth. The solutions are validated in tens of products running in foundry and proprietary fabrication plants.
Feeder protection applications can be handled by various Sepam relays including the S20, S24, S40, S44, S50, S54, S60 and S80 models. These relays provide short-circuit and overload protection for feeders in impedance earthed or solidly earthed neutral systems, with options for voltage and frequency monitoring on some models. Relays like the S41, S43, S51, and S53 can provide more specific protection for high-capacitance feeders in systems with impedance earthed, compensated, or isolated neutrals.
Designing Reliable Medical Devices by Solving Common Interconnect Challenges ...NICOMATIC
What are the most common interconnect challenges that medical device manufacturers come across during the design process, including:
Connectivity: Medical devices that are not designed to securely connect to hospital networks, the Internet of Things (IoT), or mobile patient monitoring equipment now have limited product lifecycles, as they are quickly being replaced by smarter, more connected technologies.
Flexibility: As devices become smaller and more portable, flexible component designs are critical to this achievement.
Environmental Resistance: Portable medical devices are exploding in popularity, however they are far more susceptible to mechanical damage from ingress, shock, and vibration than stationary equipment.

Latch-up Immune on-chip ESD protection for
High Voltage processes and applications
While high voltage interfaces are broadly used in many IC applications like
motor control, power management and conversion, LCD panel drivers and
automotive systems, many IC designers still lack a low leakage, cost-
effective and latch-up immune ESD protection clamp that can be applied
across various applications.
The behavior of many of the traditional on-chip ESD clamps is tied to the
process conditions, which limits the possibilities to adapt to changing
specifications. Moreover, severe reliability requirements that were long
requested only for industrial and automotive applications are now being
transferred to consumer electronics too.
This white paper introduces a new family of ESD/EOS/IEC protection
devices, called hebistor clamps that provide competitive advantage
through improved yield, reduced silicon footprint and low leakage
operation. The hebistor devices are developed to protect a broad set of
high voltage interfaces in BCD and high voltage CMOS and are branded
under the Sofics PowerQubic portfolio. Based on measurements on TSMC
0.35um 15V and TSMC 0.25um BCD 12V, 24V, 40V and 60V technology the
flexibility of the novel device is demonstrated.
