Patent ID: 6875672

Claim:
A method for manufacturing a semiconductor device, said method comprising: a recess forming step of forming recesses in a substrate proper that has semiconductor circuits and electrodes formed on one surface thereof; an embedded electrode forming step of filling a conductive material into said recesses to form embedded electrodes that constitute penetration electrodes; a connection step of electrically connecting said electrodes on said substrate proper and said embedded electrodes with one another; an organic film forming step of forming an organic film on the one surface of said substrate proper; an adhesion step of adhering a support member, which supplements the mechanical rigidity of said substrate proper, to said organic film; a semiconductor substrate forming step of removing a rear side of said substrate proper opposite to said one surface thereof until a bottom of each said embedded electrodes is exposed and protruded, thereby to form said penetration electrodes and a thinned semiconductor substrate; a film forming step of forming plating films on surfaces of the protruded portions of said embedded electrodes; and a removal step of removing said support member and said organic film from said semiconductor substrate; wherein said organic film has an adhesive property and chemical resistance to chemical substances used in respective process steps after said adhesion step, said organic film being at least dissolved in or peeled off from said semiconductor substrate by a chemical substance used in said removal step.
