ABSTRACT:
A package is formed of a plurality of laminated insulation plates respectively having windows formed in the central portions thereof. Metallized patterns are formed on the surface of at least one of the insulation plates. The semiconductor chip is received in a space defined by the windows of the insulation plates. The semiconductor chip and the metallized patterns are electrically connected to each other via bonding wires. Bumps are arranged as external terminals of the semiconductor chip in a grid form on the surface of one of the insulation plates which lies on the rear surface side of the package. The bumps are electrically connected to the metallized patterns via through holes formed in the insulation plates.
