Dry Etch and DRIE

By Rogue Valley Microdevices

Our plasma dry etch and deep reactive ion etch (DRIE) processes produce trenches, cavities, through-wafer vias, and high-aspect-ratio silicon structures. - Standard DRIE Capability: Aspect ratios up to 15:1 - Etch Geometry: Etch depths from 5µm to through-wafer with sidewall profiles of 90 ±1 degrees
