Granted: 1997-04-18
Abstract: A method for fabricating a phase shifting mask is described that can protect diffuse reflection and thereby improve the correctness degree of the pattern formed on a wafer. Grooves 57 are formed upon a transparant substrate 31 in order to reverse the phase of light, and  cromium pattern 33 is made thereupon. The goooves 57 are formed to have the depth of 3400 angstrom to 4000 angstrom. An oxide layer 39 isformed over the transparant substrate 31, grooves 57 and cromium pattern 33. Thereafter, annealing is performed so that the oxide layer 39 on the cromium pattern 33 becomes cromium oxide layer 41, and that on the transparant substrate 31 and grooves 57 are planerized.  Thereby, it is possible to prevent the light from scattering and increase the strength of the light as well as reduce light interference at the edge of the cromium pattern 33. As a result, the correctness degree thereof can be improved.
