WebNov 2, 2024 · Combined with the fact that the wafer itself is slightly elliptical in shape, this presents challenges for the bevel etch process. Historically, manufacturers have used a dry bevel etch process to address edge film and contamination removal. However, this technique can create arcing and risks damage to the silicon. WebTitanium Due to the very low vapour pressures of titanium chloride (TiCl 3) and titanium ﬂ uoride (TiF 3), pure plasma processes with accordingly halogenated process gases are not suitable for the dry etching of titanium which is why argon is usually added to increase the erosion with sputter etching.
