ABSTRACT:
A method for manufacturing a mold type semiconductor device is provided. The device includes a semiconductor chip having a semiconductor part and a metallic member connecting to the chip via a conductive layer and a connecting member. The method includes: forming the semiconductor part on a semiconductor substrate so that a cell portion is provided; forming the conductive layer on the substrate; forming a first resist layer to cover a part of the conductive layer corresponding to the cell portion; etching the conductive layer with the first resist layer as a mask so that a first conductive layer is provided; removing the first resist layer and forming a second conductive layer to cover a surface and an edge of the first conductive layer. The second conductive layer has a Young's modulus equal to or larger than the semiconductor substrate.
