ABSTRACT:
There is disclosed a TAB style BGA type semiconductor device. This semiconductor device comprises a semiconductor chip on which an integrated circuit is formed, and a polyimide tape which has a conductive pattern and which is allowed to adhere to the semiconductor chip. The conductive pattern includes a bonding portion connected to the pad of the semiconductor chip, a pad portion connected to the outside electrode, and an electrically floating island-like portion in addition to a wiring portion for connecting the bonding portion and the pad portion.
