Abstract
The Quartz etch improvement program is established to technically understand and ascertain the limits, hardware implications and process conditions associated with the etching of Quartz Photomasks. This study explores several process parameters as well as salient hardware changes and ultimately analyzes results by etching test Photomasks as well as a test structure closely emulating a Levenson-style Phase Shift Photomask.
