Patent ID: 8471371

Claim:
A semiconductor composite wiring assembly for electrically connecting electrodes of a semiconductor chip to a wiring board, the semiconductor composite wiring assembly comprising: a wiring assembly; and a lead frame electrically connected to the wiring assembly with the wiring assembly mounted thereon, wherein the wiring assembly includes: an insulating layer; a metal substrate formed on one surface of the insulating layer; and a copper wiring layer formed on the opposite surface of the insulating layer, the copper wiring layer having thereon a chip placement section, the copper wiring layer further having: first terminals each being connected electrically to one of the electrodes of the semiconductor chip; second terminals each connected electrically to the lead frame by a second connecting member; and wiring sections each adapted to connect one of the first terminals and one of the second terminals, wherein the lead frame includes: a die pad for mounting thereon the wiring assembly, the die pad having: a central area in which the semiconductor chip is mounted via the wiring assembly; and a peripheral area connected to and located around the central area with spaces formed therebetween, the spaces serving as spaces into which a resin seal flows; and lead sections located at outer positions with respect to the die pad, wherein the insulating layer, the metal substrate and the copper wiring layer of the wiring assembly are positioned over the central area and the peripheral area so as to cover the central area completely and the peripheral area at least partially beyond the extent of the spaces, and wherein at least the central area and the peripheral area of the die pad are glued to the metal substrate of the wiring assembly by resin paste.
