Abstract

PURPOSE:To exactly shield a semiconductor pellet from external moisture and prevent the pellet from deteriorating its electric characteristics by forming projections on the inside surfaces of a resin case therefor. CONSTITUTION:Projections 8a-8d flared at the ends are respectively formed on the inside surfaces of an external case 8. The projections 8a-8d are implanted into filled resin therein when the case 8 is expanded to prevent the formation of a gap between resins of two types. Accordingly, since no gap is formed between the case 8 and the filled resin even when a semiconductor device using the case 8 is used for a long time, the moisture-proofness of the semiconductor device can be improved.
