WebbThe etch per cycle (EPC) of the ALE process saturated at 0.9 nm/cycle as the gas exposure times increased. With this self-limiting behavior, SiO2 was etched with high selectivity to poly-Si and Si3N4. The dependence of the EPC on the partial pressures of HF and NH3 was found to be in good agreement with the Langmuir adsorption model. Webb15 mars 2024 · Accordingly, the possibility of the ion-driven etching regime is indicated by the decreasing SiC etching rate vs. gas pressure [ 31 ]. Similarly to other materials, the SiC etching process in high-polymerizing fluorocarbons is affected by the deposition of polymer film [ 27, 31 ].
