Title:
RESIN SEALED SEMICONDUCTOR DEVICE WHOSE UPPER PORTION IS PROVIDED WITH HEAT DISSIPATING BODY EXPOSED TO EXTERNAL AND METHOD FOR MANUFACTURING SUCH RESIN SEALED SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/080785
Kind Code:
A1
Abstract:
A resin sealed body (4) is provided with a notched section (14) for exposing outside one upper surface electrode (12a) of a semiconductor element (2) and the inner end portion (13) of a lead terminal (3a). A conductive heat dissipating body (5) is provided with a heat dissipating main body (15) arranged on an upper surface (4a) of the resin sealed body (4), and a connecting section (16), which electrically connects the heat dissipating body main body (15), the upper surface electrode (12a) of the semiconductor element (2) and the lead terminal (3a), respectively, through the notched section (14) of the resin sealed body (4). The heat capacity of the heat dissipating body (5) can be changed as needed by changing the shape of the heat dissipating body main body (15). Furthermore, since a current path is formed by connecting the connecting section (16) with the lead terminal (3a), a conventional lead frame can be used as it is, without changing the shape of an external lead (3).
