The sensing element consists of a suspended
membrane realized inside a single mono-silicon
substrate. 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 *all compared to the
traditionally built silicon micromachined
membranes. Membrane breakage is prevented by
intrinsic mechanical s*pers.
The IC interface is manufactured using a standard
CMOS process that allows a high level of
integration to design a dedicated circuit which is
