WebThe College of Engineering at the University of Utah WebA three step Deep Reactive Ion Etch (DRIE) process is developed to etch trenches of 10µm wide to a depth of 130 µm into silicon with an etch rate of 2 :5µmmin1. The aim of this process is to obtain sidewalls with an angle close to 90° . The process allows the etching of multiple trenches with high aspect ratios that are closely placed together.
