Title: Multiple layer thin film solar cells with buried contacts.
Inventor: WENHAM STUART ROSS
IPC: H01L31/06
Filed: 1995-03-31
Abstract: A multilayer solar cell structure includes a stack of alternating p-type and n-type semiconductor layers (10, 11, 12, 13, 14) arranged to form a plurality of rectifying photovoltaic junctions (15, 16, 17, 18). Low-cost cells are manufactured from low-quality material which is optimized by employing very high doping levels in thin layers. Typically, the doping levels are greater than 1017 atoms/cm3, and the thickness of the layers is related to carrier diffusion length in thickness. Contact is made to underlying layers by way of a buried contact structure comprising grooves extending down through all of the active layers, the walls of each groove being doped (33, 34) with n- or p-type impurities depending upon the layers to which the respective contact is to be connected and the grooves being filled or partly filled with metal contact material (31, 32).

Title: Method and apparatus for assembling custom glass assemblies.
Inventor: RUECKHEIM ERIC W
IPC: E06B3/677
Filed: 1995-06-02
Abstract: The present invention provides a method and apparatus for assembling a small number of custom sealed double glazing units in which spacers can have different widths and panes of different assemblies can be differently sized. In accordance with one method of the invention, a spacer (31) having sealant (34) on opposing surfaces thereof is adhered to a first glass pane (21) and a resilient member (40) is positioned alongside a portion of the spacer. A seond glass pane (26) is positioned over the spacer so that it is partially adhered to the spacer to define an interpane space (36) around which the spacer is adhered, but with the resilient member preventing contact with the whole of the spacer, so maintaining a gap between a portion of the spacer and the second glass pane. The resulting assembly is moved into a gas exchange chamber (60), and air is removed from the chamber and accordingly also the interpane space. A gas having a coefficient of thermal conductivity lower than that of air is introduced into the chamber and accordingly also the interpane space, and the glass panes are pressed together while in the gas exchange chamber to compress the resilient member and adhere the second glass pane to all of the spacer to seal the interpane space.

Title: Process for depositing a layer of material on a substrate and a plating system.
Inventor: SIMPSON CINDY REIDSEMA
IPC: C25D17/00
Filed: 1998-04-28
Abstract: An electroplating system (30) and process makes electrical current density across a semiconductor device substrate (20) surface more uniform during plating to allow for a more uniform or tailored deposition of a conductive material. The electrical current density modifiers (364 and (37) reduce the electrical current density near the edge substrate (20). By reducing the current density near the edge of the substrate (20) the plating becomes more uniform or can be tailored so that slightly more material is plated near the center of the substrate (20). The system can also be modified so that the material that electrical current density modifier portions (364) on structures (36) can be removed without having to disassemble any portion of the head (35) or otherwise remove the structures (36) from the system. This in-situ cleaning reduces the amount of equipment downtime, increases equipment lifetime, and reduces particle counts.
