Silicon-processing technology

Photovoltaic cells are currently manufactured using silicon processing technologies, and novel approaches are in development using polymers and nanostructures. By achieving cost reductions, photovoltaics are expected to take an important role in macro power generation. They can also be used as micro power sources, as long as the power and size meet the needs of the application.

CVD processing can be used to provide selective deposition on certain areas of a surface. Selective tungsten CVD is used to fill vias or holes selectively through silicon oxide layers in silicon-device technology. In this case, the silicon from the substrate catalyzes the reduction of tungsten hexafluoride, whereas the silicon oxide does not. Selective CVD deposition can also be accomplished using lasers or focused electron beams for local heating.
