Silicon Microstructures acquisition and sale to TE Connectivity
Silicon Microstructures, Inc.(SMI) was founded in 1991 as a commercial source of high-performance silicon pressure sensors, including Microelectromechanical systems sensors, and accelerometers. Its first product was a silicon sensor for very low-pressure usage.
Elmos Semiconductor acquired SMI in March 2001 from OSI Systems.[4] 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 Milpitas, California. 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.[clarification needed]
In 2019, Elmos announced the sale of Silicon Microstructures to TE Connectivity, and the subsequent closure of Elmos Group’s micromechanics division.[5]
