dry etch selectivity
These requirements are typically contradictory; in conventional parallel-plate plasma reactors such as the reactive ion etchers. (RIE), high etching rate and ... ,The ion beam etching (IBE) is a physical dry etch process. ... The wafer is held perpendicular or tilted into the ion beam, the etch progress is absolute anisotropic. The selectivity is low because there is no differentiation of the individual layers. ,– Typically used at a pressure of 1-2 Torr to give Si etch rates of 1-3 µm/min. – Very high selectivity: virtually no etch rate for Al, SiO. 2. ,. Si. ,By suitably adjusting the constituents and proportions of etchant species, a good etch-rate selectivity to other layers is achieved. Plasma etching of resists, SiO2, Si ... ,Criteria with Dry Etching The anisotropy describes the ratio of etch rates perpendicular and parallel to the substrate surface. The more isotropic the etching process is, the stronger the etching mask is underetched during the etching process. ,•Dry Etch. Three Major Materials to be. Etched: –Silicon. –Dielectric. –Metal.
