MEMSensing launches the world’s smallest commercial 3-axis accelerometer with SMIC

MEMSensing Microsystems Co. and Semiconductor Manufacturing International Corporation jointly announced the launch of the world’s smallest 3-axis accelerometer MSA330, which utilizes SMIC’s CMOS integrated MEMS device fabrication and TSV-based wafer level packaging technologies.

By vertically integrating the 3-axis accelerometer device with CMOS ASIC into a single package of 1.075×1.075×0.60mm3 (LxWxH), MSA330 achieves about 30% shrink in footprint and 70% reduction in the total size compared to the latest commercial products. It is also the thinnest of its kind, only 0.5mm after SMT and 0.6mm in total height including 0.2mm solder balls. MSA330 would be competitive not only in overall fabrication costs through all wafer level fabrication and packaging but also in miniaturization particularly for mobile and wearable applications.

“The success in MSA330 signifies SMIC the major breakthrough achieved in its fabrication of CMOS integrated MEMS devices and TSV-based wafer level packaging technologies, which is expected to enter commercial production within 2015. Such accomplishment would further benefit SMIC in broadening its manufacturing capabilities and foundry services into fabricating MEMS devices and wafer level packaging open to global MEMS customers,” said Dr. Shiuh-Wuu Lee, Executive Vice President of Technology Development of SMIC.

“MEMSensing is SMIC’s 1st domestic MEMS customer, and also one of its earliest customers worldwide which can be dated back to as early as 2009. MSA330 is the world’s 1st MEMS accelerometer enabled by WLCSP (Wafer Level Chip Scale Packaging), which is based on WLP and TSV technology. This approach belongs to the latest generation for MEMS accelerometer fabrication while other competitors are still lagging one step behind. The success for MSA330 product development proves that MEMSensing has now broadened its MEMS sensor product portfolio beyond the existing MEMS microphone and pressure sensors. We plan to allocate more resources to cooperate with SMIC to develop other advanced products and make an effort to further enrich China’s domestic MEMS industry chain,” said Dr. Li Gang, CEO of MEMSensing.
