Patent ID: 6969623

Claim:
A method for manufacturing the semiconductor device, comprising: a first step of forming a plurality of identical semiconductor chips on a semiconductor wafer; a second step of carrying out a quality test for each of a plurality of said semiconductor chips formed on said semiconductor wafer; and a third step of dividing one of a plurality of pieces of said semiconductor chips on the basis of a result of said quality test, wherein said plurality of semiconductor chips are divided into first groups made of four pieces if four pieces are determined to be possible to form a group as a result of said step of carrying out a quality test, but wherein said chips are divided into second groups made of two pieces if four pieces are determined to be not possible to form a group as a result of said step of carrying out a quality test but if two pieces are determined to be possible, and wherein said chips are divided into third groups made of one piece if neither four pieces nor two pieces are determined to be possible to form a group as a result of said step of carrying out a quality test but if one piece is determined to be possible as a result of said quality test.
