Abstract:
A method for forming an oxide layer on an electronic substrate comprising the steps of:loading at least one electronic substrate into an oxidation chamber,providing a moisture generator in fluid communication with said oxidation chamber,heating said moisture generator to a fist temperature sufficient for generating H.sub.2 O from H.sub.2 and O.sub.2,flowing gases of H.sub.2 and O.sub.2 into said moisture generator and generating H.sub.2 O,flowing said H.sub.2 O into the oxidation chamber through a first conduit and forming an oxide layer on said at least one electronic substrate,stopping said flow of gases of hydrogen and oxygen, andcontinuously heating said moisture generator and substantially preventing the condensation of H.sub.2 O on an inner wall of said moisture generator.
