WebAug 18, 2024 · Etching rates of different cuts of LN using the CHF 3 /Ar plasma. In Figure 5, we present the results using the described etching process for (a) the Ti/Al mask and (b) the Ti/Al/Cr mask. The presence of Al exposure to the plasma results in re-deposition of Al by-products, which are visible in Figure 5 a as “pyramids” or “cones”. WebAn inductively coupled plasma reactive ion etching process was developed for transferring patterns from a thin intermediate mask consisting of Ni or SiNx into GaAs. Smoothed out etch floors and sidewalls can be achieved under an approximately 200V bias by switching between an anisotropic etch phase and a deposition phase by gas chopping. The ... WebSep 1, 2005 · The LiNbO3waveguide etched at a bias power of 300 W for 40 min showed an etching depth of 4.7 μm and an etching angle of 72°, while an etching depth of 4.7 μm and an etching angle of 72° were obtained when the waveguide was etched at a bias power of 400 W for 30 min. hilda knoff crochet address
