Abstract: The construction of a film on a wafer, which is placed in a processing chamber, may be carried out through the following steps. A layer (film) of tantalum nitride material is deposited on the wafer. Next, the layer of tantalum nitride material is annealed. The deposition and annealing may both be accomplished in the same chamber, without need for removing the wafer from the chamber until both steps are completed.

Abstract: Processing of hydroxylapatite sol-gel films on titanium alloy bone prostheses. A method utilizing non-line-of-sight ion beam implantation and/or rapid thermal processing to provide improved bonding of layers of hydroxylapatite to titanium alloy substrates while encouraging bone ingrowth into the hydroxylapatite layers located away from the substrate, is described for the fabrication of prostheses. The first layer of hydroxylapatite is mixed into the substrate by the ions or rapidly thermally annealed, while subsequent layers are heat treated or densified using ion implantation to form layers of decreasing density and larger crystallization, with the outermost layers being suitable for bone ingrowth.
