It is capable to detecting pressure and is manufactured using a dedicated process developed by ST, called VENSENS. The VENSENS process allows to build a mono- silicon membrane above an air cavity with controlled gap and defined pressure. The membrane is very small compared to the traditionally built silicon micromachined membranes. Membrane breakage is prevented by intrinsic mechanical stoppers. The IC interface is manufactured using a standard CMOS process that allows a high level of integration to design a dedicated circuit which is HCLGA-16 3x3x1 mm HCLGA-16 3x3x1 mm
