Patent ID: 7728438

Claim:
A semiconductor device, comprising: a semiconductor element; a first conductive electrode, wherein the first conductive electrode is electrically connected to a circuit on a front surface of the semiconductor element; a penetrating region extending from the front surface to a back surface of the semiconductor element in a manner substantially perpendicular to the front and back surfaces of the semiconductor element, wherein the penetrating region is over the first conductive electrode; a second conductive electrode inside the penetrating region and electrically connected to the first conductive electrode; a transparent cover on the front surface of the semiconductor element, wherein a side surface of the transparent cover and a side surface of the semiconductor element are on the same plane; and a sealing resin, wherein the resin covers and is in direct contact with the side surface of the semiconductor element and the side surface of the transparent cover and a thickness of the sealing resin in direct contact with the side surface of the semiconductor element is greater than a thickness of the sealing resin in direct contact with the side surface of the transparent cover.
