Abstract
A semiconductor device having a pellet mounted on a radiating plate thereof is disclosed. The radiating plate is formed in such a shape that a central portion thereof is positioned higher than both end portions thereof. A pellet is mounted on a lower face of the central portion of the radiating plate, and an upper face of the central portion of the radiating plate is exposed to the top of a resin member. Since the upper face of the central portion of the radiating plate which has the pellet mounted on the lower face thereof is exposed from the resin member, heat generated by the pellet can be radiated efficiently.
