Elmos supplies automotive application-specific integrated circuits (ASICs).

Silicon Microstructures, Inc.(SMI) was founded in 1991 as a commercial source of high-performance silicon pressure sensors, including Microelectromechanical systems sensors, and accelerometers.

Elmos Semiconductor acquired SMI in March 2001 from OSI Systems.

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.
