Abstract:
1. A method of chemical vapor deposition of a material comprising Ge and Sb comprising: positioning a substrate having an exposed surface in a chemical vapor deposition reactor chamber; evacuating said reactor chamber including said substrate to a base pressure of less than 1E-3 torr; heating the substrate to a temperature that is less than 400° C.; providing an antimony-containing precursor and a germanium-containing precursor to said reactor chamber; and depositing a material comprising germanium (Ge) and antimony (Sb) on said exposed surface of said substrate from said precursors wherein said substrate is an interconnect structure having at least one opening therein that has an aspect ratio of greater than 10:1 and said material comprising Ge and Sb is deposited conformally within said at least one opening.
