Abstract:
1. A method of pattern layout of a photomask for pattern transfer, used in a manufacturing process for a semiconductor device for transferring an image to a photosensitive film, the method comprising: positioning patterns having belt shapes in a photomask layout for transferring an image to a photosensitive film; temporarily positioning auxiliary patterns that do not substantially transfer an image to the photosensitive film in the photomask layout according to rules based on layout of the patterns having belt shapes; selecting from the auxiliary patterns an auxiliary pattern having an end partially overlapping an end of one of the patterns having belt shapes and making contact with the pattern having the belt shape; and adjusting the position of the auxiliary pattern selected so that the end of the auxiliary pattern selected completely overlaps the end of the pattern having a belt shape and making the contact.
