Abstract:
A high temperature transducer structure, comprising:an insulator planar member having disposed on a top surface a plurality of depressions for accommodating contact areas, each depression having an associated metalized channel directed from said depression to a contact end of said planar member, a silicon sensor member having a deflectable diaphragm area associated with piezoresistive sensors, said active area surrounded by a non-active area, said non-active area having a plurality of contacts coupled to said piezoresistive sensors and directed through contact apertures to a contact surface of said silicon member, said plurality of contacts arranged in congruency with said plurality of depressions so that each contact of said sensor member is positioned in an associated depression when said sensor member is positioned on said planar member, means for securing said sensor member to said planar member to form a composite member, a metallic flat housing having external leads at a terminating end, said housing when accommodating said composite member having an associated external lead corresponding with an associated metalized channel for connecting said lead to said channel when said composite member is located in said housing.
