Power semiconductor integrated circuit package
First Claim
1. A hermetically sealed semiconductor package comprising:
- at least one integrated circuit with each integrated circuit having first and second opposed faces with the first face having at least one electrode providing at least a first circuit connection to the integrated circuit and with the second face providing a second circuit connection to the integrated circuit;
a thermally conductive base thermally coupled to the second face for conducting heat generated by operation of the at least one integrated circuit;
an insulator electrically isolating the first circuit connection from the second circuit connection;
a side wall extending upward from the base; and
a lid extending from the side wall, the base, sidewall and lid forming a hermetically sealed cavity in which the at least one integrated circuit is disposed and the lid having at least one depression projecting inward below an inner and outer surface of the lid into the cavity, touching and electrically contacting at least one of the circuit connections at a plane below the inner surface of the lid within the cavity.
