Abstract
A semiconductor device, that is approximately identical in package size to a semiconductor chip, such as a W-CSP, is devised to secure a wider area for sealing such as laser marking. A semiconductor substrate has a plurality of via electrodes extending from the bottom of the semiconductor substrate to top electrodes, a bottom wire net formed at the bottom of the semiconductor substrate such that the bottom wire net is connected to the via electrodes, and an insulative film covering the bottom wire net. A sealing area having a sealing mark is disposed at the bottom of the semiconductor substrate. The sealing area is located such that the outer circumference of the sealing area is spaced apart from the bottom wire net in a direction parallel to a sealing mark forming surface, and the outer circumference of the sealing area is disposed at the edge of the semiconductor substrate.
