摘要:
Adjusting a curvature of a substrate includes forming at least one deformed portion in a predetermined region of a substrate, wherein the substrate includes a curved region before forming the at least one deformed portion, and forming the at least one deformed portion includes irradiating the substrate in the predetermined region so as to fixedly displace substrate material in the predetermined region.
摘要:
A method of manufacturing an extreme ultra-violet lithography (EUVL) alternating phase-shift mask comprises preparing a substrate having a reflective layer, forming a light-shielding layer pattern on the reflective layer to cover part of the reflective layer while leaving a reflective region of the reflective layer exposed, forming a trench in a phase-shift region of the reflective layer by etching the reflective layer, and changing the physical structure of a non phase-shift region of the reflective region to lower its reflectivity with respect to extreme ultra-violet (EUV) light.

A polarization measuring device includes a diffraction grating and a detector. The diffraction grating is configured to diffract incident light to observe the polarization state of the light. The detector is configured to receive the light diffracted by the diffraction grating and display the polarization state of the light.
