Abstract
A metal hydride derivative wherein at least one hydrogen atom is replaced by deuterium (.sup.2.sub.1 H) or tritium (.sup.3.sub.1 H) isotope. The metal constituent of such metal hydride may be a Group III, IV or V metal or a transition metal, e.g., antimony, aluminum, gallium, tin, or germanium. The isotopically stabilized metal hydride derivatives of the invention are useful as metal source compositions for chemical vapor deposition, assisted chemical vapor deposition (e.g., laser-assisted chemical vapor deposition, light-assisted chemical vapor deposition, plasma-assisted chemical vapor deposition and ion-assisted chemical vapor deposition), ion implantation, molecular beam epitaxy, and rapid thermal processing.
