Abstract: Surface metallization technology for ceramic substrates is disclosed herein. It makes use of a known phenomenon that many metal—metal oxide alloys in liquid state readily wet an oxide ceramic surface and strongly bond to it upon solidification. To achieve high adhesion strength of a metallization to ceramic, a discrete metallization layer consisting of metal droplets bonded to ceramic surface using metal—metal oxide bonding process is produced first. Next, a continuous metal layer is deposited on top of the discrete layer and bonded to it using a sintering process. As a result a strongly adhering, glass-free metallization layer directly bonded to ceramic surface is produced. In particular, the process can be successfully used to metalize aluminum nitride ceramic with high thermal and electrical conductivity copper metal.

Abstract: An apparatus and method for manufacturing thin-film CdS/CdTe photovoltaic modules in a vacuum environment. The apparatus deposits CdS and CdTe layers onto a substrate using heated pocket deposition, a form of physical vapor deposition (PVD) in which a material thermally sublimes from a thermal sublimation source block and is deposited onto a substrate. The thermal sublimation source block includes a pocket having a lower surface into which an array of holes is formed to house plugs of deposition material. Upon heating, deposition material sublimes from a surface of each plug of deposition material, and the surface of each plug regresses into its corresponding hole while maintaining a constant surface area. The sublimation surface area of deposition material across the pocket remains substantially constant during an extended deposition process, and the deposition material is substantially free of undesired thermal radiation from the substrate.

Abstract: Direct resistive heating is used to grow nanotubes out of carbon and other materials. A growth-initiated array of nanotubes is provided using a CVD or ion implantation process. These processes use indirect heating to heat the catalysts to initiate growth.

A material source supplies the heated catalysts with carbon or another material to continue growth of the array of nanotubes. Once direct heating has commenced, the source of indirect heating can be removed or at least reduced. Because direct resistive heating is more efficient than indirect heating the total power consumption is reduced significantly.

The treatment process is useful for improving the mechanical, catalytic, chemical, or biological activity of the surfaces so treated.
