ABSTRACT:
A pad electrode is formed on a main surface of a semiconductor chip. A passivation film, which covers a surface portion of the pad electrode, is formed on the main surface of the semiconductor chip. An internal connection conductor is formed on a surface portion of the pad electrode. The semiconductor chip is covered with a molding resin which exposes only a top surface of the internal connection conductor. An external connection conductor is formed on a top surface of the internal connection conductor. The external connection conductor has a substantially flat top surface. Thereby, a plastic molded semiconductor package can be easily mounted on a printed board, and can have improved reliability after being joined on the printed board.
