Abstract
A semiconductor chip module uses a silicone adhesive between the semiconductor chip and a cap, said adhesive having sufficient bond strength to secure said cap to said chip without additional mechanical constraint while providing a direct thermally conductive path and permitting sufficient heat flow from said chip to said cap to maintain steady state operation of said semiconductor chip. The preferred silicone adhesive comprises a primerless, two-part polysiloxane-based adhesive made by reacting polydimethyl siloxane, an organosilicon compound, a polysiloxane, and a silane, in the presence of a catalyst.
