20120196397Methods of Building Crystalline Silicon Solar Cells For Use In Combinatorial Screening - Embodiments of the current invention describe methods of forming different types of crystalline silicon based solar cells that can be combinatorially varied and evaluated. Examples of these different types of solar cells include front and back contact silicon based solar cells, all-back contact solar cells and selective emitter solar cells. These methodologies all incorporate the formation of site-isolated regions using a combinatorial processing tool and the use of these site-isolated regions to form the solar cell area. Therefore, multiple solar cells may be rapidly formed on a single crystalline silicon substrate for use in combinatorial methodologies. Any of the individual processes of the methods described may be varied combinatorially to test varied process conditions or materials.08-02-2012

20090232966Stamp Usage To Enhance Surface Layer Functionalization And Selectivity - This disclosure provides methods, devices and systems for using a stamp to enhance selectivity between surface layers of a substrate, and to facilitate functionalizing selected layers. An array of flat stamps may be used to concurrently stamp multiple regions of a substrate to transfer one or more substances to the topmost layer or layers of the substrate. If desired, the affected regions of the substrate may be isolated from each other through the use of a reactor plate that, when clamped to the substrate's surface, forms reaction wells in the area of stamping. The stamp area can, if desired, be configured for stamping the substrate after the reactor plate has been fitted, with the individual stamps sized and arranged in a manner that permits stamping within each reaction well. If applied in a combinatorial process, a robotic process may be used to transfer multiple combinations of contact substances and processing chemicals to each reaction well to perform many concurrent processes upon a single substrate (e.g., a single coupon). The methods, devices and systems provided facilitate semiconductor design, optimization and qualification, and may be adapted to production manufacturing.09-17-2009
