Ribe reactive ion beam etch
WebbSecond, the thick SMA films are wet etched by hydrofluoric acid (HF) and nitric acid (HNO 3) solution, while thin films are dry-etched by reactive ion beam etching (RIBE). Third, the Si device layer is structured by reactive ion etching (RIE) using the cryo process. WebbThis paper reports the reactive ion beam etching (RIBE) of PZT with smooth surface, nearly vertical profile angle, no redeposition on the sidewall and high selectivity to Pt electrode and photoresist mask.
