Abstract:
A pressure sensing device suitable for medical use comprising:a dielectrically isolated sensor chip including a wafer having first and second surfaces, a deflectable diaphragm formed therein and defining an active area of said sensor chip surrounded by an inactive area of said sensor chip, an electronic circuit formed on said first surface in said active area and providing a signal indicative of an amount of deflection of said diaphragm, and a non-conductive coating on at least a portion of said second surface; and, a plastic header including first and second ends, a recess in said first end and a plurality of electrically conductive pins extending from said recess through said header and out said second end, said plastic header comprising a plastic having high dielectric strength, imperviousness to biological fluids and being moldable to a desired shape, the header further including a threaded coupling portion for coupling a port to the header; wherein, said sensor chip is secured within said recess of said plastic header such that said electronic circuit is in electrical contact with at least one of said pins.
