Patent ID: 8867023

Claim:
A method for determining a pattern of an original for use in projecting an image of the pattern of an original on a substrate, the method being executed by a computer, the method comprising: a designing step of designing a layout of a device including macrocells; a setting step of setting an exposure condition; an image calculating step of calculating a dimension of an image to be projected on the substrate, in a case where a pattern of the designed layout is placed on a surface of the original, under the exposure condition set in the setting step; an electrical characteristic calculating step of calculating an electrical characteristic of a pattern to be formed on the substrate in accordance with a result calculated in the image calculating step; a determining step of determining whether the electrical characteristic calculated in the electrical characteristic calculating step satisfies a requirement; and a step of modifying the layout of the device by changing the position of the macrocell while maintaining a shape of a pattern in the macrocells designed in the designing step when the electrical characteristic is determined not to satisfy the requirement in the determining step.
