Patent ID: 7484556

Claim:
A heat dissipating member which is disposed between a heat generating electronic component which when operated generates heat and reaches a temperature higher than room temperature and a heat dissipating component, wherein the heat dissipating member is solid in a room temperature state prior to operation of the electronic component and melts under heat generation during operation of the electronic component to fluidize at least a surface thereof so as to fill between the electronic component and the heat dissipating component without leaving any substantial voids, and the heat dissipating member is formed of a composition consisting of a silicone resin and a heat conductive filler, and wherein said silicone resin consists of RSiO 3/2 units (T units) and R 2 SiO 2/2 units (D units) or RSiO 3/2 units, R 2 SiO 2/2 units and R 3 SiO 1/2 units (M units) for end-capping wherein R is a substituted or unsubstituted monovalent hydrocarbon radical having 1 to 10 carbon atoms.
