    摘要: The invention provides a plotting pattern data production method suitable for use for production of a mask for exposure or a semiconductor integrated circuit wherein a minimum plotting grid of a magnitude used in an existing apparatus can be used and a semiconductor integrated circuit pattern having a desired size can be formed accurately. The method comprises the steps of: (A) producing an n-fold design pattern by multiplying a design pattern to n times a minimum design pattern unit length (where n>1) and then converting the n-fold design pattern so that profiles thereof may come on those minimum plotting grids adjacent the profiles thereby to obtain a plotting pattern, and (B) (a) setting, for each portion of the plotting pattern which includes any of the profiles of the n-fold design pattern, a dose amount in accordance with a ratio in area of the n-fold design pattern which occupies the minimum plotting grid, but (b) setting a predetermined dose amount for each portion of the plotting pattern which does not include any profile of the n-fold design pattern.
