Patent ID: 8399295

Claim:
A method for manufacturing a semiconductor device comprising: mounting chips over a first surface of a support substrate, each of the chips including pads and a first insulating film covering the pads, the support substrate having a second surface that is located on a same side of the first surface and above a level of the first surface, a first height from the first surface to the second surface being higher than second heights from the first surface to bottom surfaces of the first insulating films and being lower than third heights from the first surface to upper surfaces of the first insulating films in a state that the chips are fixed to the first surface of the support substrate; filling a filler material in a space between the chips and covering the chips and the second surface with the filler material; grinding the filler material and the first insulating films to a point at which (a) the second surface is exposed, (b) ground surfaces of the first insulating films are, after grinding, located between the bottom surfaces of the first insulating films and the upper surfaces of the first insulating films before grinding, and (c) the ground surfaces of the first insulating films are, after grinding, located at a same level as an upper surface of the filler material after grinding and the second surface of the support substrate; and after the filler material and the first insulating films are ground, forming wirings over the filler material and the first insulating film, the wirings connecting a pad of one of the chips to a pad of another chip.
