Tin forms nonvolatile compounds with fluorine at the process temperatures enabling tin to function as an etch mask. We investigate atomic layer deposition
WebDec 16, 2024 · Area-selective atomic layer deposition (ALD) of dielectrics on chemically similar growth and nongrowth surfaces is very challenging. In this study, we use aminosilane inhibitors to achieve selective blocking of ALD of Al 2 O 3 on plasma-deposited SiO 2 versus plasma-deposited SiN x . WebSelective atomic layer deposition (ALD) is a critical component of advanced manufacturing and offers an alternative to lithographic procedures. Traditional precursors such as AlCl 3 or AlCl 2 CH 3 are used for Al 2 O 3, but these precursors show poor are selectivity with increased deposition cycles. These smaller precursors more easily ...
WebJun 10, 2013 · 2.1. Area-Selective ALD on SAM . Patterned SAMs are commonly used as growth-preventing masks for selective-area ALD. Selective-area ALD is the growth of thin films on the substrate surface on designated sites only. Selective-area ALD requires that the chosen regions of the surface are inert to ALD precursors.
