Patent ID: 7811857

Claim:
A method of manufacturing a semiconductor device, comprising the steps of: a first step of forming an insulating film on a first surface on a front side of a semiconductor wafer, the front side of which a plurality of devices formed thereon, the insulating film having an opening portion from which an electrode pad of each device is exposed; next, a second step of forming a conductor layer on the insulating film, the conductor layer being patterned in a required shape to cover the opening portion from which the electrode pad is exposed; next, a third step of forming a resist layer on the conductor layer, so as to have an opening portion from which a terminal formation portion of the conductor layer is exposed; next, a fourth step of forming a metal post on the terminal formation portion of the conductor layer with the resist layer being used as a mask, wherein the metal post is at a same height from the first surface as the resist layer, wherein an almost planarized surface is formed above the front side; next, a fifth step of performing thinning of the semiconductor wafer to a predetermined thickness by grinding a back surface on a back side thereof which is reverse to the front side having the metal post formed thereon; next, a sixth step of sealing a front-side wafer surface with sealing resin, with a top portion of the metal post being exposed, after removing the resist layer; next, a seventh step of bonding a metal bump to the top portion of the metal post; and next, an eighth step of dividing the semiconductor wafer having the metal bump bonded thereto to separate said device from other of the plurality of devices.
