Abstract

Semiconductor devices are encapsulated in a thermosetting resin filled with aluminum nitride particles. The aluminum nitride particles have an outer layer of Al--O--N, into which is incorporated amorphous Si--O, which renders them hydrolytically stable. The aluminum nitride particles impart very high thermal conductivity to the cured resin. In addition, the cured resin has a CTE similar to that of the encapsulated semiconductor device, and has excellent dielectric properties.
