Patent ID: 7510910

Claim:
A production method of a semiconductor device, including the steps of: forming integrated electronic circuits corresponding to a plurality of semiconductor chips on a semiconductor wafer, and forming electrodes on a surface of the semiconductor wafer by taking them out from the electronic circuits; forming a pattern of a first resin layer on the surface of the semiconductor wafer except for a scribe line that is to be a dicing region; forming on the first resin layer a pattern of a first wiring layer electrically connected to the electrodes; forming a pattern of a second resin layer to cover the first resin layer and the first wiring layer except for the scribe line; and dicing the semiconductor wafer on the scribe line; wherein in the step of forming the second resin layer, the second resin layer is formed on a smaller area than that of the first resin layer, so that a side surface and an upper surface of each of the first resin layer and the second resin layer form a stepwise shape.
