Transparent substrate coated with at least one thin layer based on silico nitride or oxynitride and method of obtaining same

摘要

A transparent glass substrate (1) is coated with a silicon nitride-based or oxynitride-based thin film (2) which contains 30-60 (preferably 40-50) at.% Si, 10-56 (preferably 20-56) at.% N, 1-40 (preferably 5-30) at.% O and 1-40 (preferably 5-30) at.% C. Also claimed is a process for depositing the above thin film (2) by CVD from a silicon precursor (preferably a silane and/or silazane) and a nitrogen precursor, the nitrogen precursor being in the form of an amine, preferably a 1-6C alkyl prim., sec. or tert. amine, especially ethylamine, methylamine, dimethylamine, butylamine or propylamine.
