Abstract:
In a manufacturing step in which a structure of target of screening is formed on a semiconductor substrate in the middle of manufacturing process before a semiconductor device is finished, screening of potential defects of a gate insulating film is performed for each wafer at one time so that the semiconductor device is caused to appear as an initial defective product when the finished semiconductor device is subjected to an electrical characteristic test. Provided are a semiconductor device, and a method of manufacturing a semiconductor device which enables reliable screening of potential defects in a short period of time.

Claim (Index 2):
The method of manufacturing a semiconductor device according to  claim 1 , further comprising, between the forming the gate electrode film and the screening the gate insulating film, removing the gate electrode film and the gate insulating film that are formed on the back surface of the semiconductor substrate of the wafer and a peripheral portion of a front surface of the semiconductor substrate of the wafer, and\n wherein the removing the gate electrode film and the gate insulating film comprises setting a gate insulating film removal width from an end surface of the semiconductor substrate of the wafer to an end surface of the gate insulating film to be smaller than a gate electrode film removal width from the end surface of the semiconductor substrate of the wafer to an end surface of the gate electrode film.
