Patent ID: 8492763

Claim:
A semiconductor device, comprising: a semiconductor substrate including a chip area formed at an inward side of the semiconductor substrate when viewed in a direction perpendicular to a surface of the semiconductor substrate; an edge seal disposed around the chip area on the surface to protect the chip area; a plurality of pad pieces disposed on an edge region on the surface; and an insulating film pattern covering edge portions of the plurality of pad pieces at a side of the edge seal, at least at one side of the chip area on the surface in a first direction and at least at one side of the chip area on the surface in a second direction, wherein each of the semiconductor substrate and the chip area has a rectangular shape, the edge seal includes a first portion extending along a first side of the chip area, and a second portion extending along a second side adjacent to the first side of the chip area the plurality of pad pieces include a plurality of first pad pieces disposed parallel to the first side on the edge region, and a plurality of second pad pieces disposed parallel to the second side on the edge region; and the insulating film pattern includes a plurality of first patterns, each covering the edge portion of the first pad piece at a side of the first portion, and a plurality of second patterns, each covering the edge portion of the second pad piece at a side of the second portion; wherein the plurality of first patterns cover the edge portions of the plurality of first pad pieces at a side of the first portion without covering an edge portion of the first portion at a side of the plurality of first pad pieces, and the plurality of second patterns cover the edge portions of the plurality of second pad pieces at a side of the second portion without covering an edge portion of the second portion at a side of the plurality of second pad pieces.
