Patent ID: 8193100

Claim:
A method of manufacturing a semiconductor device comprising: applying a first resist layer on a substrate including a semiconductor substrate; manufacturing a first exposure mask; disposing the first exposure mask above the substrate in an exposure apparatus; irradiating a charged beam or light onto the first resist layer by way of the first exposure mask in a state that the first exposure mask is chucked by the chuck unit of the exposure apparatus; forming a first resist pattern by developing the first resist layer after the irradiating the charged beam or the light onto the first resist layer; and forming a first pattern by etching the substrate using the first resist pattern as a mask, wherein manufacturing the first exposure mask comprises generating or preparing flatness variation data relating to a mask blanks substrate to be processed into an exposure mask, the flatness variation data being data relating to a change of flatness of the mask blanks substrate caused when the mask blanks substrate is chucked by a chuck unit of the exposure apparatus; generating position correction data of a pattern to be drawn on the mask blanks substrate based on the flatness variation data such that a mask pattern of the first exposure mask comes to a predetermined position in a state that the first exposure mask is chucked by the chuck unit; and drawing a pattern on the mask blanks substrate, wherein drawing the pattern includes drawing the pattern with correcting a drawing position of the pattern and inputting drawing data corresponding to the pattern and the position correction data into a drawing apparatus.
