Abstract
In a semiconductor device, a first semiconductor chip is stacked on a wiring substrate and has first electrode pads disposed at predetermined positions on an upper surface thereof. A second semiconductor chip is stacked on the first semiconductor chip through an insulating member in an offset manner so that the first electrode pads are exposed. Support members support a back surface of a protruding portion of the second semiconductor chip through the insulating member.
