This book was released on 1988 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: High purity, crystalline AlN and SiC thin films have been prepared by the chemical vapor deposition of (CH3)2AlN2)3 and (CH3)HSiCH2)3, respectively, at temperatures under 800 C. The use of these 'designed precursors' results in film stoichiometries of nearly one-to-one and the evolution of non-corrosive reaction by-products. In addition, no carrier gas is required. Preliminary studies of the interaction of the (CH3)HSiCH2)3 system with a clean Si(100) surface indicate interesting precursor adsorption and decomposition behavior with epitaxial growth of SiC on Si(100) at or below 700 C. It is anticipated that information from these studies will be used to improve the deposition processes and aid in the design of new precursors.
