Chinese-owned Silex Microsystems remained the top MEMS foundry in 2021, followed by Teledyne MEMS and TSMC ranked second and third, according to Yole Group.

Foundry revenues were grew 21 percent in 2021 to reach US$690 million. This is 5.1 percent of the MEMS market which Yole puts at US$13.6 billion in 2021 but it is growing faster (see Bosch leads vendor ranking in strong MEMS market).

X-Fab and Sony are ranked fourth and fifth but notably Bosch, STMicroelectronics and UMC are tiny players in this market with annual sales at between $10 million and $20 million each. This probably reflects the strong demand in the market for their direct sales of MEMS leaving little idle capacity.

Vanguard International Semiconductor Corp. (Hsinchu, Taiwan), which acquired the MEMS foundry business of Globalfoundries in 2019 is prominently ranked alongside Philips Engineering Solutions.

Some 98 percent of the shares of Silex Microsystems AB were acquired by GAE Ltd., a Hong Kong based investment holding company in 2015 (see China buys Swedish MEMS foundry, builds fab). GAE in turn became a subsidiary of Navtech Inc. which has changed its name to Sai Microelectronics Inc. and is now listed on the Shenzhen stock exchange.
