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 1):
A method of manufacturing a semiconductor device, the semiconductor device having a gate insulating film and a gate electrode film on a semiconductor substrate of a wafer, the method comprising:\n forming the gate insulating film on the semiconductor substrate of the wafer; forming the gate electrode film on an entire surface of the semiconductor substrate of the wafer, the semiconductor substrate of the wafer including the gate insulating film; screening, after the forming the gate electrode film, the gate insulating film by generating a potential difference between the gate electrode film which is formed on the entire surface of the semiconductor substrate of the wafer, and a back surface of the semiconductor substrate of the wafer to apply an electric field to the gate insulating film; determining the semiconductor substrate of the wafer which has been subjected to the screening; and patterning the gate electrode film after the determining the semiconductor substrate of the wafer.
