Abstract

Method for depositing a layer containing Al; N, and Si on a substrate which comprises providing a substrate to be coated, a carrier gas, and a gaseous mixture of nitrogen source compounds, aluminum source compounds and silicon source material and heating the substrate to a temperature in the range of about 500.degree. to about 1,300.degree. C to thereby cause formation on the substrate of a layer containing Al, N, and Si; and products obtained by the method.
