Abstract:
1. A semiconductor device comprising: a semiconductor element that has a first surface on which an external connection terminal is formed and a second surface opposite the first surface, and a thickness of 10 μm or more and 150 μm or less; a plate that faces the second surface; and a resin binder that adheres the second surface and the plate, wherein the plate has a rigidity higher than that of the semiconductor element; wherein the second surface of the semiconductor element comprises a surface-finished surface such that the second surface of the semiconductor element is free from having a damaged layer thereon; wherein an outer shape of the plate is larger than that of the semiconductor element; and wherein the resin binder covers a peripheral side face of the semiconductor element, and furthermore at a portion that is interposed between the second surface and the plate the resin binder allows the semiconductor element to deform in a thickness direction thereof.
