    Abstract: According to one embodiment, a fine processing method includes determining a resist amount required for each first region of a pattern formation surface and a total amount of resist. The method include dividing the total amount of resist by a volume of one resist drop to determine the resist drops total number. The method include determining a provisional position for the resist drop of the total number. The method include assigning the each first region to nearest one resist drop, and partitioning again the pattern formation surface into second regions assigned to the each resist drop. The method include determining a divided value by dividing the volume of the one resist drop by the required total amount of resist determined. The method include finalizing a final position of the each resist drop, if a distribution of the divided value in the pattern formation surface falls within a target range.

  • Publication number: 20100304280
    Abstract: A method of manufacturing a semiconductor device using a template on which a pattern is formed beforehand is disclosed. An error between a position of the pattern formed on the template and a reference position where the pattern is to be formed is obtained. An outer shape of the template is processed in accordance with the obtained error. The error of the template is corrected by distorting the template through application of pressure to a side face of the template whose outer shape is processed. The pattern is transferred onto a transfer layer formed on a semiconductor substrate by using the template in which the error is corrected.
