Title:
WIRING BOARD COMPOSITE BODY, SEMICONDUCTOR DEVICE, AND METHOD FOR MANUFACTURING THE WIRING BOARD COMPOSITE BODY AND THE SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/029813
Kind Code:
A1
Abstract:
A wiring board composite body is composed of a supporting substrate, and wiring boards formed on the upper and the lower surfaces of the supporting substrate, respectively. The supporting substrate is composed of a supporting body, and metal bodies arranged on the upper and the lower surfaces of the supporting body, respectively. The wiring board is provided with at least an insulating layer, upper and lower wirings insulated by the insulating layer, and a via for connecting the upper and the lower wirings. The wiring board mounted on the metal body constitutes a wiring board provided with the metal body. Thus, the supporting body for supporting the metal body is effectively used in a process of forming the wiring board on the metal body, and the wiring board composite body, which has less warping and swells in the manufacturing process and in a finished structure and can increase the wiring substrate production quantity, is provided. A semiconductor device and a method for manufacturing such wiring substrate composite body and the semiconductor device are also provided.
