Lithography pupil
WebAs the critical dimension of integrated circuits is continuously shrunk, thick mask induced aberration (TMIA) cannot be ignored in the lithography image process. Recently, a set of pupil wavefront optimization (PWO) approaches has been proposed to compensate for TMIA, based on a wavefront manipulator in modern scanners. However, these prior … Web1. A lithography pupil shaping optical system is composed of illumination mode generation unit (1), rotatable wave plate (2), polarization beam splitter unit (3), ring I generation unit (4) and ring II generation unit (5).Said illumination mode generation unit (1) is composed of diffractive optical element (101) and zoom collimating lens group (102).
