High pressure oxidation of metal films

Last updated:

Abstract:

Methods of processing thin film by oxidation at high pressure are described. The methods are generally performed at pressures greater than 2 bar. The methods can be performed at lower temperatures and have shorter exposure times than similar methods performed at lower pressures. Some methods relate to oxidizing tungsten films to form self-aligned pillars.
