Patent number: 10008435Abstract: A semiconductor device including a semiconductor chip and a heat dissipation unit (heat sink) is configured as follows. The heat dissipation unit (heat sink) includes a resin tape, and a fin constituted of a graphite sheet and protruding from the resin tape. The fin, including graphene, is disposed on the semiconductor chip such that the graphene is disposed in a direction crossing a surface of the semiconductor chip. The heat dissipation unit is a rolled body in which the graphite sheet and the resin tape are layered and rolled. Thus, by use of the graphene as a constituent material of the fin, thermal conductivity is improved, whereby a heat dissipation characteristic is improved. Furthermore, since the fin is protruded from the resin tape, an exposed area of the fin is increased, and accordingly, the heat dissipation characteristic can be improved.Type: GrantFiled: April 6, 2017Date of Patent: June 26, 2018Assignee: RENESAS ELECTRONICS CORPORATIONInventor: Yoshihisa Matsubara
