Patent ID: 8217509

Claim:
A semiconductor device comprising: a semiconductor chip; a support board which supports said semiconductor chip; a plurality of terminal electrodes provided on said semiconductor chip; a plurality of external terminal electrodes which connect said terminal electrodes to the outside; a fan out section which electrically connects said terminal electrodes and said external terminal electrodes, said fan out section including an insulating layer which covers said terminal electrodes; through electrodes which connect to said terminal electrodes and pierce the insulating layer; and metal wirings which connect to the through electrodes and are formed on the insulating layer, a first metal film provided on said support board; and a second metal film provided on said support board through the first metal film, said the second metal film having a fit hole to fit said semiconductor chip, wherein said semiconductor chip is fitted into the fit hole so that the side of the semiconductor chip on which said terminal electrodes are provided is exposed, and is adhered to the fit hole with an adhesive, and wherein spacing between said adjacent external terminal electrodes is larger than spacing between said adjacent terminal electrodes.
