Patent ID: 8125079

Claim:
A resin molded semiconductor device comprising: a semiconductor packaging substrate having a first area on a front surface of said semiconductor packaging substrate, a second area laterally outside of an outer periphery of the first area on the front surface, and a back surface opposite the front surface, a semiconductor element on the first area on the front surface, an electrode on an outer periphery of the semiconductor element on the first area on the front surface, a first external terminal on the second area on the front surface, a second external terminal on the back surface, a connector electrically connecting the electrode to the semiconductor element, a resin molded portion covering the first area including the semiconductor element and the connector, wherein the resin molded portion has: a top surface substantially parallel to the front surface of the semiconductor packaging substrate, a recessed portion depressed into the top surface of the resin molded portion, and an upwardly projecting portion of the top surface of the resin molded portion, wherein the second area of the front surface, and the back surface, of the semiconductor packaging substrate are not covered by the resin molded portion, and the second area is exposed to air.
