WebSep 30, 2024 · The recipes of such photoresists are well optimized for a uniform thickness across the wafer. However, special thick photoresists are used as a sacrificial layer for MEMS devices. These thick photoresists reflow in the vertical position and lead to non-uniform thickness; consequently, the yield is decreased. This paper has optimized a … WebPhotoresist descum is an additional gentle photoresist etching process after photoresist patterning and development.
