Abstract

PURPOSE:To obtain a semiconductor device of high heat dissipating property where a semiconductor chip larger than a conventional one in power consumption can be mounted by a method wherein a heat dissipating board provided with a protrusion is mounted in a recess which exposes the side of an island opposed to its side that is correspondent to a region where a semiconductor chip is mounted. CONSTITUTION:In a semiconductor device, a semiconductor chip 4 is fixed to one side of an island 3 and connected to leads 2 through bonding wires 5, and the part of a lead frame inside the lead 2 is sealed up with resin. At this point, a resin sealing process is carried out using a molding die which is so constituted as to enable the side of the island 3 of the lead frame opposed its side where the semiconductor chip 4 is mounted to be exposed. Thereafter, a heat dissipating board 7 is mounted on the exposed side of the island 3 of the lead frame. Therefore, as a semiconductor device of this design is high in heat dissipating properties, a semiconductor chip of high power consumption can be mounted on the device concerned.
