Tao2 dry etch
WebThe dry etch rates of the TiO2 films on Al2O3 were approximately double those of Al2O3 in all samples deposited at different temperature ranges. The etch rates tended to decrease slightly with increasing TiO2 deposition temperature. In the case of a 200-nm-thick TiO2 single layer, the etch rates were 1.1–1.2 nm/s, which were higher than those ... WebHome - Department of Chemical Engineering

WebIon Beam Etching. The ion beam etching (IBE) is a physical dry etch process. Thereby argon ions are radiated onto the surface as an ion beam with about 1 to 3 keV. Because of the energy of the ions, they strike out material of the surface. The wafer is held perpendicular or tilted into the ion beam, the etch progress is absolute anisotropic. WebPlates .
