Title: Resin-sealed semiconductor device
Inventor: KAGOSHIMA YOSHINORI
IPC: H01L23/28
Filed: 1991-07-24
Abstract: PURPOSE:To obtain a small-sized thin type resin-sealed semiconductor device excellent in heat dissipation which can prevent generation of package damage due to heating when the package is mounted on a printed board. CONSTITUTION:The whole outer periphery of an island 10 of a lead frame is turned into a sidewall part 11 surrounding a semiconductor chip 12 by drawing work, and the rear of the island is exposed to the lower surface of a package. Water content evaporated and expanded by heating is released from the interface between the sidewall part 11 and a mold resin part 15 to the outside, so that the package is not damaged. Since a resin layer is not present on the rear face of the island 10, excellent heat dissipation is realized and the package can be thin.
