Abstract: PROBLEM TO BE SOLVED: To provide a photomask capable of suppressing blurring of an image projected on work with respect to a gray mask having a transmissivity modulating layer. SOLUTION: In a step 31, a function of blurring due to a photomask and an exposure optical system is obtained, and in a step 32, an original pattern is subjected to reverse convolution with the function of blurring to obtain a mask pattern. Since this mask pattern includes a phase component in addition to an amplitude component, in steps 33 and 34, the objective photomask having a phase shifting layer disposed on a transmissivity modulating layer is produced. A fine structure can be precisely transferred to a resist layer on work by using the photomask, therefore a fine structure can be more precisely produced. COPYRIGHT: (C)2004,JPO
