Bosch continues to be the leading vendor of MEMS components in a market expected to show 9% compound annual growth rate for the next few years, according to Yole Group.
The market analyst said that the global MEMS market was worth $13.6 billion in 2021 and is expected to reach $14 billion in 2022. The CAGR will be 9 percent over the period 2021 to 2027. At the end this period the annual market is expected to be about $22 billion.
The second and third ranked vendors are Broadcom and Qorvo respectively who continued to benefit from their sales of RF MEMS filters for 5G applications, as did Skyworks much further down the ranking.

Meanwhile STMicroelectronics, Qualcom and TDK – the acquirer of InvenSense a few years ago – grew sales significantly in 2021. This kept them in positions four through six in the ranking.
Yole states that the MEMS market was driven both by increased unit sales and increases in average selling prices. The unit sales were driven by the sensorization of consumer and automotive applications and advances in the medical and industrial end markets.
The consumer market was responsible for about $7.5 billion or 55 percent of the market in 2021. Automotive and Industrial applications were responsible for $2.4 billion and $2.2 billion respectively, with medical and aerospace buying $0.7 billion of MEMS each.
Of the total revenue a relatively small but growing portion was provided by foundry sales. That market moved from $570 million in 2020 to $690 million in 2021, about 5.1 percent of the total.
Production capacity expansion
In line with the general trend in the semiconductor sector MEMS players are investing in production capaciry including the likes of Bosch, SilTerra, Silan Microelectronics, FormFactor. However, the equipment market is saturated leading to high equipment prices and delivery times of more than 15 months, Yole said.
As a result many companies are acquiring production lines from other vendors. Yole identified Silex acquired Elmos’ 200mm wafer line, and Mitsumi acquired Omron’s MEMS business. Bosch announced the construction of a 300mm MEMS line that will open in 2026. This will be a first for production of MEMS on 300mm wafers.
The 2022 and 2023 markets for MEMS are likely to remain strong as some MEMS foundries have production sold out until the end of 2023. ASPs are likely to continue to increase as vendors face margin pressures due to higher operating costs due to the current microeconomic and macroeconomic situation.
This is likely to lead to inventory stockpiling and a downturn in 2023 and thereafter, although the long-term prospect for the MEMS market remains strong.
