Title:
METHOD OF QUANTITATIVELY CHARACTERIZING ADULTERANTS OF SILANES AND COATED SUSCEPTOR
Document Type and Number:
WIPO Patent Application WO/2013/138016
Kind Code:
A3
Abstract:
Described herein is a method of indirectly quantitatively characterizing at least one adulterant of a silane. The method comprises etching a substrate in situ to give a very clean substrate surface, epitaxy of silicon formed from the silane on the surface, and a sensitive analysis of the resulting silicon film. Also described is a coated susceptor.
