Patent ID: 8237258

Claim:
A semiconductor module, comprising: a semiconductor device comprising: a semiconductor substrate; a device electrode formed on said semiconductor substrate, the device electrode having a first surface facing the semiconductor substrate and a second surface opposite to the first surface; and a protective layer, having an opening, covering said semiconductor substrate and allowing the device electrode to protrude from said protective layer through the opening; and a device mounting board comprising: an insulating resin layer provided on the protective layer, the insulating resin layer having a first surface facing the protective layer and a second surface opposite to the first surface; a wiring layer provided on the second surface of said insulating resin layer; and a bump electrode extending from said wiring layer and being provided in the insulating resin layer, wherein the device electrode is substantially symmetrical in a cross-sectional view in relation to a center axis of the opening in the protective layer, a portion of the device electrode which protrudes from the protective layer is provided in the insulating resin layer, and the bump electrode and the device electrode are electrically connected to each other in the insulating resin layer.
