Photolithography mask printing

WebOct 15, 2008 · Wafer-plane inspection (WPI) technology meets the needs of advanced-mask manufacturers to identify lithographically significant defects while ignoring other, lithographically unimportant defects.1,2 WPI detects defects based on a model of how mask features would actually print on the photoresist. The ability to ignore non-printing defects … WebOptical lithography (also known as photolithography) is a technique based on transferring a pattern from a mask to a surface using a radiation source, such as visible UV light or X-rays. For this process, a photosensitive material is exposed through a photomask and the exposed areas suffer a change on its chemical properties.
