Highly selective … Web8 apr. 2024 · Here the mechanism is similar to that of C4F8/SF6. However, in this case, low-temperature help with the formation of the sidewall passivation with a SiOF species serves to limit lateral etching. The SiOF at the bottom of the feature is again removed by the ions normal to the surface. Once the wafer returns to room temperature the SiOF desorbs. metea court apartments buchanan mi
