摘要

A charged particle beam photolithography machine includes an electron gun, a deflector, a wafer stage, a standard substrate formed with a chip-shaped first mark group having a plurality of first marks and a chip-shaped second mark group having a plurality of second marks, a correction map having misalignment factors of the first marks based on positions of the second marks, and a deflection control unit for controlling an amount of deflection in the deflector. The charged particle is irradiated on a wafer while the deflection control unit makes reference to the correction map and corrects the amount of deflection as equivalent to the misalignment factors.
