20130020669 | METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE, RESIN SEALING APPARATUS, AND SEMICONDUCTOR DEVICE - When a resin sealed package is molded with use of a release film for the purpose of preventing generation of a flash on a surface of a seal glass, the seal glass may be broken by being compressed and bent by the release film at a portion of the seal glass below which there is a cavity. The present invention prevents this breakage of the seal glass. More specifically, the present invention prevents breakage of the seal glass by forming a recess corresponding to a compression allowance of the release film at a mold die above the portion of the seal glass below which there is the cavity, or at the seal glass itself, and thereby releasing a pressure from the release film. | 01-24-2013 |
