Described herein are precursors and methods for forming silicon-containing films. In one aspect, the precursor comprises a compound represented by one of following Formulae A through E below:
In one particular embodiment, the organoaminosilane precursors are effective for a low temperature (e.g., 350° C. or less), atomic layer deposition (ALD) or plasma enhanced atomic layer deposition (PEALD) of a silicon-containing film. In addition, described herein is a composition comprising an organoaminosilane described herein wherein the organoaminosilane is substantially free of at least one selected from the amines, halides (e.g., Cl, F, I, Br), higher molecular weight species, and trace metals.
本文描述了用于形成含硅薄膜的前体和方法。在一个方面,前驱体包括由下式 A 至 E 之一代表的化合物:
在一个特定的实施方案中,有机氨基硅烷前体对含硅薄膜的低温(如 350° C 或更低)、原子层沉积(ALD)或等离子体增强原子层沉积(PEALD)有效。此外,本文还描述了一种包含本文所述有机氨基硅烷的组合物,其中有机氨基硅烷基本上不含至少一种选自胺、卤化物(如Cl、F、I、Br)、高分子量物种和痕量金属的物质。
