. Its first product was a silicon sensor for very low-pressure usage. Elmos Semiconductor acquired SMI in March 2001 from OSI Systems. SMI began production on higher performance, system level sensors and microstructures, wireless, RF and bus addressable microstructures. In August 2002, SMI acquired the IC Sensors' wafer fabrication operations and wafer R&D group and relocated to

. The following year, Silicon Microstructures undertook a significant and complete wafer fabrication upgrade to expand the facility for full 6" wafer handling. This facility processed primarily 6 inch wafers and has advanced technical capabilities including deep reactive ion etching ( DRIE) and plasma enhanced fusion bonding. In 2019, Elmos announced the sale of Silicon Microstructures to
