Patent ID: 7910460

Claim:
A metallic electrode forming method for a semiconductor device comprising: forming a bed electrode on a principal surface of a semiconductor substrate, wherein the bed electrode is electrically connected to a semiconductor element; forming a protective film on the bed electrode, and forming an opening in the protective film so that the bed electrode is exposed from the opening; forming a metallic film on the protective film to cover the protective film and the opening of the protective film; mounting the semiconductor substrate with the metallic film on an adsorption stage, and measuring a surface shape of at least a part of the metallic film by a surface shape measuring means, wherein the adsorption stage adsorbs and fixes the semiconductor substrate on the stage, and wherein the part of the metallic film is disposed on the protective film; deforming the semiconductor substrate based on a surface shape data of the part of the metallic film by using a deforming means capable of displacing the semiconductor substrate so that a difference between the principal surface of the semiconductor substrate and a cutting surface is within a predetermined range, and wherein the deforming means is disposed on a stage side; measuring a surface shape of the principal surface of the semiconductor substrate, and determining whether a difference between the cutting surface and the principal surface of the semiconductor substrate is within a predetermined range; and cutting the semiconductor substrate with the metallic film along with the cutting surface so that the metallic film is patterned to be a metallic electrode when the difference between the cutting surface and the principal surface of the semiconductor substrate is within the predetermined range.
