Abstract:
1. A semiconductor wafer comprising: a substrate on which an element forming region and a scribe line region formed around the element forming region are provided; an accessory pattern having a TEG pad formed on the scribe line region; a protective film for covering the element forming region of the substrate; and supporting films, located in an opening formed in the scribe line region, for covering a portion of the accessory pattern locally, wherein the supporting films support edges of the TEG pad while avoiding a portion of a scribe line region along which the accessory pattern is diced with a dicing blade; and a portion of a surface of the TEG pad not covered by the supporting films is directly exposed in the opening, wherein the supporting films are formed only on a part where the accessory pattern is formed, and a width of an opening of an area where the supporting film is not formed in the scribe line region is increased by protruding amounts of the supporting films in the opening.
