Transducer for use in harsh environments

A pressure sensor for use in a harsh environment comprising:

• a substrate;
• a sensor die directly coupled to said substrate by a bond frame positioned between said substrate and said sensor die, said sensor die including a generally flexible diaphragm configured to flex when exposed to a sufficient differential pressure thereacross;
• a piezoelectric or piezoresistive sensing element at least partially located on said diaphragm such that said sensing element provides an electrical signal upon flexure of said diaphragm;
• and
• a connecting component electrically coupled to said sensing element, wherein said bond frame is made of an alloy material and said connecting component is electrically coupled to said sensing element by the same material of said bond frame.

• a sensor die directly coupled to said substrate by a bond frame positioned between said substrate and said sensor die, said sensor die including a generally flexible diaphragm configured to flex when exposed to a sufficient differential pressure thereacross, wherein said bond frame generally extends around said diaphragm;
• and
• a piezoelectric or piezoresistive sensing element at least partially located on said diaphragm such that said sensing element provides an electrical signal upon flexure of said diaphragm;
• and
• a connecting component electrically coupled to said sensing element at a connection location, wherein said bond frame is made of a hypoeutectic alloy and said connecting component is electrically coupled to said sensing element by the same hypoeutectic of said bond frame.
