WebReactive Ion Etching (RIE) Reactive Ion Etching (or RIE) is a simple operation and an economical solution for general plasma etching. A single RF plasma source determines both ion density and energy. Our RIE modules deliver anisotropic dry etching for. an extensive range of processes. WebSmooth anisotropic dry etching of ZnS, ZnSe, CdS, and CdTe in electron cyclotron resonance CH4/H2/Ar discharges at low pressure (1–25 mTorr) and low direct‐current (dc) bias (−100 to −250 V dc) is reported. The presence of CH4 at low flow rates is necessary to obtain the best morphologies and to retain the stoichiometry of the surfaces, although H2/Ar …
