Frequently Asked Questions
What is the MEMS market outlook in China?
China MEMS market is projected to reach RMB 250B by 2028 growing 15%+ annually. Automotive MEMS (IMU, pressure, gas sensors for ADAS and EVs) is the fastest-growing segment at 30%+ CAGR. Consumer MEMS (microphones, fingerprint, IMU for smartphones and wearables) remains the largest segment at 50%+ share. Industrial MEMS (flow, pressure, vibration sensors) is growing steadily for smart manufacturing applications.
Can China MEMS compete with STMicroelectronics and Bosch?
Chinese MEMS companies match or exceed global leaders in specific segments: Goertek MEMS microphones are comparable to Knowles and InvenSense; AAC MEMS speakers lead in acoustic performance. However, in high-performance IMUs (accelerometer+gyroscope) for automotive and industrial, STMicroelectronics and Bosch maintain significant technology leads in noise performance, temperature stability and reliability. China automotive MEMS qualification (AEC-Q100) remains a key gap being addressed.
What is MEMS foundry situation in China?
China has several MEMS foundries including Silex Microsystems (acquired by Navitar), MEMSensing (Shanghai), and ROFS (Xi'an). However, most Chinese MEMS companies use TSMC and GlobalFoundries for volume production. China domestic MEMS foundry capacity is expanding but process maturity lags TSMC by 2-3 generations. The government is investing in MEMS-specific foundry capacity to reduce dependence on TSMC for MEMS production.
Which MEMS sensors does China produce domestically?
China manufactures MEMS accelerometers (Goertek, AAC), gyroscopes (Senodia, Infineon China), pressure sensors (Nova Sensors (Shanghai)), and environmental sensors (Bosch (China), Sensirion partnership). Goertek is the world's largest MEMS microphone supplier, producing over 1 billion units annually.
What is China's MEMS foundry capability?
China has multiple MEMS dedicated foundries including MEMSIC (Hangzhou), Silterra (Xiamen), and advanced MEMS lines at SMIC and HLMC. These foundries offer surface and bulk micromachining processes with feature sizes down to 0.18 microns, supporting both automotive and consumer MEMS production volumes.
