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 12):
The method of manufacturing a semiconductor device according to  claim 11 , further comprising repeating a plurality of times:\n removing, after the patterning the second gate electrode film, a gate insulating film that is previously formed; forming a new gate insulating film on the semiconductor substrate of the wafer; forming a new gate electrode film on the entire surface of the semiconductor substrate of the wafer which includes the new gate insulating film; screening, after the forming a new gate electrode film, the new gate insulating film by generating a potential difference between the new gate electrode film which is formed on the entire surface of the semiconductor substrate of the wafer, and the back surface of the semiconductor substrate of the wafer to apply an electric field to the new gate insulating film; determining the semiconductor substrate of the wafer which has been subjected to the screening; and patterning the new gate electrode film after the determining the semiconductor substrate.
