Patent ID: 7396620

Claim:
An exposure method for exposing a pattern on an original form onto an object through a projection optical system, said exposure method comprising the steps of: obtaining, for each piece of information of resist applied to a first object, a correlation among an exposure dose for exposing the first object, a focus state of the first object in the projection optical system, and a pattern shape formed on the first object exposed with the exposure dose and the focus state; acquiring information of resist applied to a second object different from the first object; determining an exposure dose for exposing the second object, and a focus state of the second object in the projection optical system, based on the correlation obtained for the first object by said obtaining step and the information of the resist applied to the second object acquired by said acquiring step; and transferring the pattern formed on the original form onto the second object in accordance with the exposure dose and focus state determined by said determining step.
