WebJul 14, 2024 · Subsequently, area selective ALD of Pt was obtained at the unaffected sidewalls of the trench. Figure 3 Slide from Stacey Bent on topographically-selective ALD. 2. Rong Chen from Huazhong University of Science and Technology introduced a new concept that she referred to as facet-selective ALD. WebShort-chain aminosilanes, namely, bis(N,N-dimethylamino)dimethylsilane (DMADMS) and (N,N-dimethylamino)trimethylsilane (DMATMS), have been used as Si precursors for atomic layer deposition (ALD) of SiO 2.In this work, the DMADMS and DMATMS Si precursors are utilized as inhibitors for area-selective ALD (AS-ALD).

WebJan 8, 2024 · Bottom-up nanofabrication by area-selective atomic layer deposition (ALD) is currently gaining momentum in semiconductor processing, because of the increasing need for eliminating the edge placement errors of top-down processing. Moreover, area-selective ALD offers new opportunities in many other areas such as the synthesis of catalysts with ... WebIn a sense area-selective ALD utilizes effects that historically have annoyed ALD users, namely that due to the chemical nature of ALD, nucleation can depend on the initial surface. WebSelective adsorption of α,β-unsaturated aldehydes (α,β-UALs) is a prerequisite for the hydrogenation of α,β-UALs to high-value unsaturated alcohols, but a quantitative description of the interactions between the C═C/C═O bond of α,β-UALs and the catalysts is still lacking. Herein, based on comprehensive density functional theory calculations, we developed a … profinet to profibus
