Abstract:
Provided are apparatuses and methods for super resolution imaging photolithography. An exemplary apparatus may include an illumination light generation device configured to generate illumination light for imaging a pattern included in a mask through the mask. The illumination light may include a high-frequency spatial spectrum such that a high-frequency evanescent wave component of spatial spectrum information for the light is converted to a low-frequency evanescent wave component after being transmitted through the mask pattern. For example, the illumination light generation device may be configured to form the illumination in accordance with a high numerical aperture (NA) illumination mode and/or a surface plasmon (SP) wave illumination mode.
