Manufacturing method for exposure mask, generating method for mask substrate information, mask substrate, exposure mask, manufacturing method for semiconductor device and server

1. A method of manufacturing a semiconductor device, comprising:

chucking an exposure mask having a pattern, which is manufactured by an exposure mask manufacturing method, on a mask stage of an exposure apparatus;

illuminating the pattern of the exposure mask by a lighting optical system, and focusing the pattern to make an image of the pattern on a substrate by a projecting optical system; and

patterning the substrate based on the image made on the substrate to form a corresponding pattern to form a semiconductor device,

wherein the exposure mask manufacturing method comprises:

acquiring first information showing a surface shape of a surface of each of a plurality of mask substrates, and second information showing flatness of the surface of each of mask substrates after the mask substrate is chucked on a mask stage of an exposure apparatus obtained by simulation on the basis of flatness of the surface of each of the mask substrates measured by a flatness measuring apparatus and a structure of a mask chuck of the exposure apparatus;

forming a correspondence relation of each of the mask substrates, the first information, and the second information;

selecting one second information showing a desired flatness among the second information of the correspondence relations, and preparing a further mask substrate having the same surface shape as the surface shape shown by the first information which is in the correspondence relation including the selected second information; and

forming a desired pattern on said further mask substrate.
