Patent ID: 7635077

Claim:
A method of attaching a sensing die to a substrate comprising: forming substrate circuitry on said substrate, said substrate circuitry including at least one electrical contact; forming a sensing element on said sensing die for sensing a physical property of a media applied to said sensing element, and sensing die circuitry including at least one electrical contact for electrically connecting said sensing die circuitry to said substrate circuitry; defining at least one bonding area on the surface of said sensing die; defining at least one corresponding bonding area on the surface of said substrate; providing an ASIC on or in said sensing die or said substrate, said ASIC being programmable to calibrate an output of said sensing element to compensate for temperature effects of said sensing element; bonding substantially simultaneously, with conductive bonding material, said sensing die electrical contact(s) and said sensing die bonding area(s) to said corresponding substrate electrical contact(s) and said substrate bonding area(s), respectively, to thereby form a sensor; and arranging said sensing die bonding area(s), whereby, bonding said sensing die bonding area(s) to said substrate bonding area(s) forms a pressure seal for isolating said electrical contacts and said ASIC from said media applied to said sensing die.
