High thermal resistance bonding material and semiconductor structures using same

摘要

A high thermal resistance bonding material for semiconductor chips includes a binder such as epoxy or polyimide and high thermal resistance material dispersed therein such as glass micropheres, glass beads, ceramic microspheres and ceramic beads. The particles of high thermal resistance material are sieved to obtain particles of generally uniform size. In plastic-encapsulated semiconductor chips, each chip is enveloped by the bonding material.
