Abstract:
1. A method for manufacturing a semiconductor module, the method comprising: a first process of preparing a semiconductor substrate in which a circuit element and an electrode electrically connected to the circuit element are provided on a surface thereof; a second process of forming a metal sheet having a bump on a main surface and a first groove provided on the main surface, the bump being integrated with the main surface and the first groove being depressed with respect to the main surface, wherein the bump is contiguously and seamlessly integrated with the main surface; and a third process of press-bonding the metal sheet and the semiconductor substrate by way of an insulating layer and electrically connecting the bump with the electrode in a manner such that the bump penetrates the insulating layer wherein, in the third process, the insulating layer, which is pushed out by the bump as the bump penetrates the insulating layer, flows into the first groove.
