Apparatuses and methods for changing an intensity distribution of light within an illumination field without distorting the telecentricity of the light
摘要:
An apparatus for changing an aggregate intensity of a light within an illumination field of a photolithography system having a blade structure and a first actuator. The blade structure is configured to be positioned along an optical path of the photolithography system between an illumination system and a reticle stage so that, when the illumination system provides the light having the illumination field, the blade structure is substantially at a center of the illumination field and a first portion of the light within the illumination field impinges upon the blade structure. The first actuator is coupled between a first portion of the blade structure and a frame of the photolithography system and is configured to move at least the first portion of the blade structure in a first direction so that a second portion of the light within the illumination field impinges upon the blade structure.
