Abstract:
1. A method for manufacturing a semiconductor device, comprising: forming a first resist post on a connection pad of a semiconductor chip; forming a second resist post on a support member; mounting the semiconductor chip on the support member apart from the second resist post; forming an insulating layer that covers the semiconductor chip, the first resist post, and the second resist post; removing the insulating layer to expose a surface of the first resist post and a surface of the second resist post; removing the first resist post and the second resist post to form a first through hole and a second through hole in the insulating layer, the first through hole thereby exposing the connection pad, and the second through hole thereby exposing the support member; forming a wiring layer that is in electrical contact with the connection pad via the first through hole and is in contact with the support member via the second through hole and is elongated over the insulating layer; and removing at least a part of the support member to expose the wiring layer as a rear pad in a surface of the insulating layer opposite to a surface in which the first through hole is formed.
