EL SEGUNDO, USA & BANGALORE, INDIA: In a recent report, iSuppli predicted that driven by new demand from consumer electronics (CE) and wireless applications, the global market for microelectromechanical systems (MEMS) will expand to $8.8 billion in 2012, up from $6.1 billion in 2006.

I caught up with Jérémie Bouchaud, Director and Principal Analyst, MEMS, iSuppli Corp., to find out more about the dip in the fortunes of the mainstay products and the latest trends in the MEMS market, especially, the significance of consumer electronics applications such as motion sensors for gaming, laptops and DSCs, and mobile handsets. Excerpts from an interview:

CIOL: Are you indicating that the mainstay products for MEMS actuators, inkjet heads and DLP chips, will lose market share? Or, is it a slight dip?

Jérémie Bouchaud: MEMS actuators, include inkjet and DLP, and also RF MEMS switches. While selling prices stay constant, MEMS inkjet heads are losing shipments at a rate of 6 percent per year over the forecast period, so the market grows only slightly at 0.4 percent CAGR from 2006-2012.

DLP shipments continue to grow, but price erosion is running at 10 percent CAGR, which means that the market is shrinking at close to 5 percent per year to 2012. RF MEMS switches are the one bright spot that helps the market for this type of MEMS device to recover slightly in 2012. RF MEMS switches will grow at 100 percent CAGR over this time to top $260 million in 2012.

CIOL: The new wave is partly founded in the rapid rise of consumer electronics applications such as motion sensors for gaming, laptops and DSCs, and mobile handsets. How much share are these segments likely to garner?

JB: All types of sensors in wireless communications and consumer electronics (inertial, pressure, microphones, filters, oscillators etc) exceed $1,5 billion: or 17 percent of the total MEMS market. Specifically, the motion sensing opportunity, including accelerometers and gyroscopes, for consumer applications like MEMS accelerometers for mobile phones (e.g., image rotation such as in iPhone and Nokia phones), gaming (Nintendo Wii, Playstation 3), etc., and gyros (mostly digital still cameras and camcorders, gaming like Playstation 3) will grow at over 20 percent CAGR from 2006 to 2012 to exceed $680 million, about 8 percent of the total market.

CIOL: You also mentioned automotive as a key area for MEMS. What kind of growth do you see for automotive?

JB: Automotive grows at 8 percent CAGR to reach $2.1 billion in 2012, up from 1,3 billion in 2006. The market is largely driven by mandates for tire pressure monitoring, electronic stability control systems and reduced emissions, accelerating growth for pressure and inertial sensors.

CIOL: When you say that "new players have a chance to address a relatively open market", what would those markets be?

JB: The consumer electronics market is more open than the automotive sector, which features established, long-term supply arrangements, and production cycles lasting five or more years.

CE applications are characterized by fast time-to-market and short product lifetimes. For example, mobile phones that change yearly or even more frequently, and supply agreements satisfied by fast manufacturing ramp-up and ability to meet seasonal demand spikes, and often several suppliers in the same product, (e.g. ST and ADI in Wii). As sensor specifications are more relaxed than automotive, price and footprint are most decisive.

CIOL: Will there be a growth in dedicated mass production facilities then?

JB: Several large MEMS players, e.g., STMicroelectronics, Freescale and Bosch Sensortec, have or are now invested in upgrading to 8" production facilities to meet the higher demand from the consumer sector. By 2011, at least 12 companies will operate at this larger wafer size.

Some companies like Analog Devices are at the limit of their current capacity, due to its strong automotive sensor offering, and has recently decided to work with non-MEMS CMOS foundries like TSMC, a first in the industry. UMC will also join the MEMS community, partnering with Asian Pacific Microsystems.

CIOL: How do you see entrants investing in R&D?

JB: R&D rates run high in automotive (12-15 percent of MEMS revenues) and even higher in consumer (can be 15-20 percent). The high R&D rate is needed to sustain leading edge products in fast moving markets. Deep R&D pockets are needed, a luxury that is not available to all.

CIOL: Can you elaborate a bit on the market consolidation?

JB: Today, the share of the MEM revenues in the hands of the top 30 MEMS companies grew at about the same rate as the market. The markets that drive growth in MEMS are consumer electronics and automotive sensors.

The sensors will be increasingly commoditized due to extreme price pressure in both sectors, and iSuppli expects the production of MEMS devices for these two markets to be concentrated among fewer companies in the future. One facet is manufacturers attempting economies of scale by combining sales in automotive and consumer areas, e.g. at Bosch, and in future with Freescale and ST.

Other companies are pioneers and hold a strong market position for a relatively long time. Examples are TI with DLP chips and Knowles with MEMS microphones. We also expect more M&As in the near future to exacerbate the consolidation.
