Application of a 2-D anisotropic etching simulator on perforated etching of quartz wafer

DOI

Description

This paper describes features of a new anisotropic etching simulator and its applications on predicting perforated etching shape of quartz wafer. Specialized flow chart and relative process was designed to deal with etching after perforation. We present here two examples of its application on Z-plate and one example on AT-plate quartz crystal to show its good performance.
