WebNov 26, 2014 · Silicon dioxide thin film deposition on silicon using tetraethylorthosilicate (TEOS) was described for the first time in. 1 It was shown that TEOS is able to decompose in argon and hydrogen ambient at temperatures above 500°C producing SiO 2 films with acceptable deposition rate (DR). WebDec 21, 2024 · In this paper, the mechanism for PE TEOS oxide pitting is studied and two workable solutions to adopt PE TEOS as PMD oxide in 3D NAND are proposed. The first is to substitute part of PE TEOS with HDP oxide. The second is to apply plasma dry etching instead of wet etching after the subsequent CMP.

WebJun 1, 1989 · Because of our experiences, a two-step sol-gel process [34-38] was employed with tetraethoxysi- lane (TEOS) as the alkoxysilane. We already found that with this method the separate steps of hydrol- ysis and dimerization, followed by prolonged hy- drolysis and polycondensation, can be resolved qualitatively [39]. WebThe reactivity of tetraethoxysilane (TEOS) used in many sol-gel syntheses can be increased by prehydrolysis. In contrast to one-step prehydrolysis acidic two-step prehydrolysis causes an increase of the reactivity of the low molecular species provided the total water/TEOS ratios are the same in both cases.
