Abstract
A method of forming at low temperatures silicon- and nitrogen-containing ceramic or ceramic-like coatings for the protection of electronic devices. The coatings are produced by the ceramification at temperatures of, or below, 400 degrees Centigrade of preceramic silicon nitrogen-containing polymer coatings deposited from a solvent solution. The coatings are useful for planarizing the surfaces of electronic devices and for passivation.
