PURPOSE: To obtain a resin-sealed semiconductor device which prevents an island and a suspender for a TAB tape from moving. CONSTITUTION: An IC chip 5 is placed on an island 2, the IC chip 5 and LF leads 1 are connected by TAB leads 4 which are supported by a suspender 3, and the whole assembly is sealed with a sealing resin 7. At this time a distance HM from the surface of the island up to the rear surface 'of the suspender, a distance HU from the surface of the suspender up to the surface of a resin package and a distance HL from the rear surface of the island up to the rear surface of the resin package are made nearly equal. That is to say, HM≈HU≈HL. Consequently, since the circulation route of an injection resin has an equal resistance, the resin flows equally, so that the suspender or the like does not move. |
