Abstract
A semiconductor device which remains highly reliable and is easy to mount even when a bonding pad pitch is reduced. The semiconductor device is featured in that a thermally conductive support substrate in which a semiconductor chip is fixed to a recessed portion is mounted on the reverse side of an insulating tape, that is, a TAB substrate having a conductor pattern on the surface; and solder balls are placed on the front side of the insulating tape to ensure connection to the conductor pattern on the front side through holes.
