WebMar 5, 2024 · The XeF 2 etch process is a purely chemical one and usually results in a rough etched surface. The tool is operated in a pulsed mode in which the etch chamber is repeatedly filled with XeF 2 gas and, then, pumped out (to 0.3 Torr). You can also add N 2 gas, together with XeF 2 gas, into the etch chamber for some applications.
