Abstract:
An evaluation method according to an embodiment is to evaluate a precision of an aperture formed with multiple openings, and includes steps of forming a first evaluation pattern based on evaluation data using multiple electron beams generated by electron beam that has passed through the aperture, dividing the aperture into multiple regions, each of the regions including the multiple openings and defining the multiple divided regions, forming a second evaluation pattern based on evaluation data using the electron beam that has passed through a first divided region among the multiple divided regions, comparing the first evaluation pattern with the second evaluation pattern, and evaluating the precision of the aperture based on the comparison result between the first evaluation pattern and the second evaluation pattern.

Claim (Index 9):
A correction method to correct a dose amount of each of multiple electron beams that pass through an aperture formed with multiple openings, the method comprising:\n executing the evaluation method according to  claim 3 ; obtaining a first correction value based on a difference in size of respective markings in the second evaluation pattern relative to a marking in a preset reference pattern; obtaining a second correction value based on a difference in size between the marking in the second evaluation pattern and the marking in the first evaluation pattern using an evaluation result through the evaluation method; and correcting the dose amount of the electron beam that has passed through the first divided region based on the first correction value, and correcting the dose amount of the electron beam that has passed through the divided region other than the first divided region based on a sum of the first correction value and the second correction value.
