Paper Abstract

The photomask industry is constantly reaching towards next-generation technology that can advance today's semi-conductor applications. One of the most successful and widely used techniques for advancing the current lithography capability and meeting many of the next-generation requirements is through the use of phase-shifting photomasks (PSM). Resolution enhancements techniques implemented through the use of PSMs can be a powerful tool in meeting both today's and tomorrow's demanding lithographic requirements. For this work, effects of changing etch process parameters on the quartz dry-etching process performance is investigated. Considerations are given to phase depth uniformity, sidewall profile and reactive ion etch lag in the analysis of the quartz etch performance.
