Psibar® CVD Type
Chemical Vapor Deposition manufacturing methods bond a polysilicon layer
to a stainless steel diaphragm at the molecular level to produce a sensor with
superior long term drift performance. Common batch processing semiconductor
manufacturing methods are used to create a polysilicon strain guage bridge with Capacitance Types
terrific performance at a very reasonable price. CVD construct
