发明名称 Pattern forming method
摘要 To achieve down-sizing and improvements of throughputs, light exposure and charge beam exposure are sometimes used together. In case of performing exposure of a desired pattern in a plurality of stages, a positional displacement of each of exposure patterns in the stages leads to a decrease in exposure accuracy. According to the present invention, in case of forming a fine pattern by exposure after exposure of a rough pattern, the exposure position of the rough pattern is adjusted, based on a latent image of the rough pattern which has been subjected to exposure. As a result, a positional displacement between rough and fine patterns is reduced so that a desired pattern can be formed with high accuracy.
