Abstract:
1. A semiconductor device comprising: a semiconductor element mounted on a substrate by being joined to the substrate by an under-fill material; at least one electronic part arranged around the semiconductor element; and a heat radiation member bonded to a backside of said semiconductor element by a bonding material, wherein the heat radiation member has an isolation part extending between an outer circumference of said semiconductor element and said electronic part, wherein said isolation part is a member different from said heat radiation member and attached to said heat radiation member, and is formed in a frame shape so as to surround an entire circumference of said semiconductor element, an extreme end of said isolation part extending to a position adjacent to said substrate, wherein said bonding material covers side surfaces of said semiconductor element and reaches and contacts with said under-fill material, wherein said isolation part surrounds and contacts with said bonding material covering the side surfaces of said semiconductor element.
