WebMar 6, 1998 · 4. Summary. Etching of Si and SiO 2 in an RFI high density plasma etcher was studied using the response surface method and quantitative models were established. In SF 6 /CHF 3 /O 2 mixtures, Si etch rate always increased with the SF 6 /CHF 3 ratio since SF 6 provided more active F-containing species. WebInteraction of single γ-Al2O3 and γ-Ga2O3, and mixed γ-Al2O3/γ-Ga2O3 xerogels with CHF3 at intermediate temperatures results in partial fluorination. Fluorinated oxides remain amorphous and retain a considerable part of the initial surface area; for the fluorinated Al-based materials surface areas in all cases exceed 100 m2 g-1.

WebRF power range was from 130W to 170W. Selectivity was affected by how to fast remove Al2O3 by BCl3. The etch profile is varied from isotropic to anisotropic by adjusting plasma conditions. Therefore, the profile is strongly related with two parameters such as BCl3 and Cl2, an increase of the its affect on anisotropic sidewall characteristics. Con-
