ABSTRACT:
A method is described which forms amorphous phosphorus-nitrogen-oxygen material having excellent thermal stability and low reactivity to a wide variety of chemicals. The material is manufactured using a chemical vapor deposition process. The reaction chamber is maintained at a temperature between about 400.degree.-900.degree. C. with a suitable substrate placed therein. Reaction gases containing phosphorus-nitrogen-bearing compounds and a source of oxygen are passed through the chamber to deposit the phosphorus-nitrogen-oxygen film onto the substrate.
