Webthe formation of the trench hole, and L BG is determined during the formation of the actual gate electrode. Supporting Information 2: Optimization of the one-route all-dry etching process (ORADEP) As described in the main body of the paper, one cycle of the one-route all-dry etching process (ORADEP) consists of two steps: (1) a C 4 F 8 WebBut as the HF is depleted (used up) from the solution the etch rate would change. Thus, a Buffering solution is added that controls the HF concentration as: NH 4 F NH 3 HF The HF concentration remains “saturated”. As HF is consumed etching SiO 2, the above reaction replaces the HF, keeping the etch rate constant. Wet Chemical Etching: seta grip flooring installation instructions
