1. A method for manufacturing a mold type semiconductor device including a semiconductor chip having a semiconductor part and a metallic member, the metallic member connecting to the semiconductor chip through a conductive layer and a connecting member, the conductive layer and the connecting member being sandwiched between the metallic member and the semiconductor chip, the method comprising the steps of:
forming the semiconductor part on a principal plane of a semiconductor substrate so that a cell portion is provided;
forming the conductive layer on the principal plane of the semiconductor substrate;
forming a first resist layer to cover a part of the conductive layer, the part 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,
wherein the second conductive layer has a Young's modulus, which is equal to or larger than that of the semiconductor substrate.
