At least a groove for separating a semiconductor substrate into a first region of a relatively large area and a second region of a relatively small area is formed. An insulating film is formed on the surface of the semiconductor substrate including the interior of the groove. The insulating film is etched using an etching mask having a lattice window pattern in such a manner that openings corresponding to the lattice window pattern are formed in the first region. As an alternative, openings corresponding to a single opening pattern are formed in the first region using an etching mask having the single opening pattern and the lattice window pattern, and the insulating film is etched in such a manner that openings corresponding to the lattice window pattern are formed in the second region. In both cases, the remaining insulating film is polished off.

摘要:
In the verification method of the present invention, a defect that is to cause a problem in fabrication is extracted from a mask pattern. The mask pattern is one obtained by deforming a mask pattern of a photomask used in a photolithography process so as to provide a transferred image close to a desired design pattern. The verification method includes the steps of: determining the exposure dose in the photolithography process; simulating the photolithography process on a computer based on the determined exposure dose; checking whether or not the desired design pattern has been obtained; and locating a fault point and outputting the result.
