Abstract:
A production method of a semiconductor device which allows a semiconductor chip piece bonded with adhesive to be efficiently obtained and allows a semiconductor chip and a wiring board to be excellently connected together. The production method comprises the step of preparing a laminate (60) in which a dicing tape (9), an adhesive layer (3) and semiconductor wafer (6) are laminated in this sequence so that the circuit surface (6a) of the semiconductor wafer (6) faces the dicing tape (9) side, the step of recognizing a cut position by recognizing the circuit pattern (P) of the circuit surface (6a) from the rear surface (6b) of the semiconductor wafer (6), and the step of cutting at least the semiconductor wafer (6) and the adhesive layer (3) in the thickness direction of the laminate (60) to thereby obtain a semiconductor chip piece connected with the wiring board, whereby it is possible to prevent the semiconductor chip from contaminating and from being lost due to scattering or flowing out.
