ABSTRACT:
A wiring pattern having a plurality of leads is formed on the under surface of an insulating film. The inner lead portion of each of the leads is bonded to a corresponding one of bump electrodes formed on pads of a semiconductor chip and the outer lead portion thereof is connected to a corresponding lead wire formed on a printed circuit board. The outer lead portion of one of the leads which acts as a ground line is connected to a grounded lead wire which is formed on the printed circuit board. A shield plate is bonded to the under surface of the leads via insulating adhesive agent. The shield plate is electrically connected to the grounded lead wire. The semiconductor chip and the inner lead portions are hermetically sealed by use of potting resin.
