Abstract:
A plotting pattern data production method for producing plotting pattern data used to plot a pattern using an electron beam, comprising the steps of:producing an n-fold design pattern by multiplying a design pattern by n times a minimum design pattern unit length, wherein a minimum plotting length between lines of a plotting grid used in plotting with an electron beam is N times the minimum design pattern unit length, with N being larger than 1 and n being larger than 1 but less than N;obtaining a plotting pattern by converting the n-fold design pattern such that profiles of the n-fold design pattern coincide with lines of the plotting grid adjacent to the profiles of the n-fold design pattern; andsetting a first predetermined dose amount for each portion of the plotting pattern that includes any profile of the n-fold design pattern in accordance with a ratio in area of the n-fold design pattern which occupies the plotting pattern and setting a second predetermined dose amount for each portion of the plotting pattern that does not include any profile of the n-fold design pattern.
