20130154075 | SEMICONDUCTOR DEVICE - In a QFP with a chip-stacked structure in which a lower surface of a die pad is exposed from a lower surface of a sealing member, a semiconductor chip having a BCB film, which is made of a polymeric material containing at least benzocyclobutene in its backbone as an organic monomer and formed on its surface, is mounted at a position (second stage) that is away from the die pad. As a result, even when moisture invades through the interface between the die pad and the sealing member, it is possible to prolong the time required for the moisture to reach the semiconductor chip, and subsequently to make moisture absorption defect less likely to occur. | 06-20-2013 |
