MEMS Front-End Manufacturing Trends

Though MEMS standardization will never happen, companies are optimizing their own technology platforms. Such process innovations will drive MEMS equipment and materials to a 7% CAGR over 2012-2018.

Innovative processes are fueling the MEMS equipment & materials market. We forecast that demand for MEMS-related equipment will grow from ~ $378M in 2012 to > $510M by 2018, at a CAGR of 5.2% over the next five years. It’s interesting to note that our MEMS equipment market forecast will follow a cyclical up/downturn similar to what the mainstream IC equipment market underwent. The demand for materials and related MEMS consumables will grow from ~$136M in 2012 to > $248M by 2018 at a CAGR of 10.5% over the next five years.

Today, MEMS fabrication is still very diversified and lacking in standardization; Yole Développement’s rule « one product, one process » still applies. Indeed, MEMS has a different story than IC and doesn’t follow the same roadmap as the semiconductor industry. Thus, it’s still common to see many players with radically different manufacturing approaches for the same MEMS device, sometimes within the same company (i.e. both the CMOS MEMS and hybrid approaches can be used for inertial devices or microphones).
However, as MEMS becomes a commodity product with a quicker time-to-market compared to previous generations, anything that speeds up the commercialization process is welcome. MEMS packaging is evolving in a different direction than front-end processing, and Yole Développement has already identified that packaging standardization will become increasingly critical in order to support the massive volume growth in unit shipments, and decrease overall costs associated with MEMS & sensor content. For example, microphone packaging is very similar between one manufacturer and another. Additionally, this report shows that at the front-end level, companies are developing in-house technological platforms targeted for different MEMS devices.

  7. 7. What is changing in MEMS manufacturing, why …• Today, MEMS fabrication is still very diversified without standarization: – The Yole MEMS rule « one product, one process » still rules• MEMS has a different sory and do not follow a roadmap as the semiconductor industry does. ‒ Indeed, many players have different manufacturing approaches for the same device and even in a same company, processes will be radically different for same MEMS (e.g. CMOS MEMS or hybrid approach for inertial or microphones).• As from development to products, MEMS take typically 20-30 years from research to commercialization, any way to speed up the commercialization process is welcome.• So we see a clear trend for smaller, more cost effective MEMS devices specially for the consumer market where small form factor and low cost are mandatory. – For MEMS Packaging, there is already a trend toward standardization. – And standardization is becoming increasingly critical to support the massive volume grow in unit shipments along with decreasing overall costs associated with MEMS & sensor content, in particular related to their packaging.• But MEMS size reduction cannot last forever  e.g. for inertial, a minimal mass is needed for movement detection. – Today, die size reduction is mostly achieved by packaging innovation (e.g. new gold bonding, TSV interconnect) that adds extra manufacturing cost but reduce the Si size. Overall, the final cost is lower compared to previous generation. – New detection principle are currently developed under the roof of R&D Institutes (M&NEMS concept at Tronics’)  this could be the next step to lower MEMS size at the silicon level. © 2013• 7
  8. 8. What is changing in MEMS manufacturing, why …• After 50 years of development, the MEMS industry keeps innovating in processes.• Standardization is on its way in packaging and, as MEMS competition shifts to the systems level, competition at the process level could be less important.• After years of developments, some process steps found their sweet spots: – TSV technology is step by step diffusing into the MEMS industry. Both IDMs (ST, Bosch) and foundries now master the technology. – Thin films PZT (either CSD or sputtered deposition) is linked to new MEMS devices such as wafer-level auto focus or uncooled IR sensors. – Temporary bonding will be used as thinner wafers will be processed (e.g. oscillators). – Cavity SOI success could depend on the success of NF as an open platform for MEMS manufacturing.• The MEMS equipment & materials market will keep growing: – The equipment market will have a 5.2 % CAGR, growing from $378M in 2012 to $512M in 2018. – The equipment market will have a 10.5 % CAGR, growing from $136M in 2012 to $248M in 2018.• It is unlikely to see standardization happening in the MEMS industry. But the need for more performing, smaller and cost effective devices lead MEMS players to continuously modify & adapt their process. Although no cross standardization like CMOS will happen, in-house technology or product platforms help MEMS players to speed up time-to-market. © 2013• 8

  13. 13. Equipment Market Forecast for MEMS devices• We forecast the demand for equipment used in the MEMS area to grow from ~ $378M in 2012 to > $510M by 2018 at a CAGR of 5.2% over the next 5 years.• It is interesting to see the MEMS market forecast to follow a cycle-like up & downturn similar to what the mainstream IC equipment market undergo.• Reasons behind is because the current MEMS devices market growth is driving a need for new tools investment. But the capacity will exceed the real production need in 2016. After installed base will no longer cope with increased MEMS demand, the need for new equipment will grow again (2018).
