    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.

    摘要: A method of forming a photomask using a calibration pattern that may exactly transfer a desired pattern to a substrate. The method includes providing one-dimensional calibration design patterns each having first design measures and providing two-dimensional calibration design patterns each having second design measures; obtaining one-dimensional calibration measured patterns using the one-dimensional calibration design patterns and obtaining two-dimensional calibration measured patterns using the two-dimensional calibration design patterns; obtaining first measured measures of the one-dimensional calibration measured patterns and obtaining second measured measures of the two-dimensional calibration measured patterns; establishing a correlation between the first measured measures and the second measured measures; and converting a main measured measure of a main pattern into a corresponding one of the first measured measures using the correlation.

    摘要: A method of forming a rim type of photomask prevents a chrome pattern formed in the 0°-phase shift region of the mask substrate from being irregular and hence, ensures that the border of the 0°-phase shift region has a uniform width. First, a light blocking layer is formed on a quartz substrate. A select portion of the light blocking layer is etched to form a patterned light blocking layer, and the underlying quartz substrate is etched to a predetermined depth to form a 180°-phase shift region. Then, a fluid material layer is formed on the quartz substrate without an electron beam lithography process. The fluid material layer covers a central portion of the patterned light blocking layer and leaves an outer peripheral portion of the patterned light blocking layer exposed. Subsequently, the patterned light blocking layer is etched using the fluid material layer as a mask to form a light blocking pattern and to expose the substrate along a border adjacent the 180°-phase shift region. Finally, the fluid material layer is removed.
