Langmuir modeling of ion assisted si etching
WebbPhysical Etching • Ion etching is much more directional ( field across plasma sheath) and S c ≈ 1, i.e. ions don't bounce around (or if they do, they lose their energy.) • Etching species are ions like CF 3 + or Ar+ which remove material by sputtering. • Not very selective since all materials sputter at about the same rate.

Webb30 aug. 2024 · Model-based analysis of the InP etching kinetics revealed that 1) the InP etching process is mainly provided by the chemical etching pathway; 2) the non-monotonic change in the InP etching rate cannot be explained by the chemical effects of Br and Cl atoms; and 3) the HCl molecules may have sufficiently contributed to the … Webb15 nov. 2002 · 11. 15:34. The name RIE can be slightly misleading. The proper name of this type of etching process should be an ion-assisted etching, since the ions in this etch process are not necessarily reactive. For example, in many cases argon ions are used to increase ion bombardment. As an inert atom, argon is not chemically reactive …
