| 20090010626 | PROCESSING MULTILAYER SEMICONDUCTORS WITH MULTIPLE HEAT SOURCES - A method of adjusting the heat transfer properties within a processing chamber is presented. Chamber properties may be determined and adjusted by adjusting the thermal mass of an edge ring disposed in the processing chamber. | 01-08-2009 |
| 20100173495 | SUBSTRATE PROCESSING APPARATUS USING A BATCH PROCESSING CHAMBER - Aspects of the invention include a method and apparatus for processing a substrate using a multi-chamber processing system (e.g., a cluster tool) adapted to process substrates in one or more batch and/or single substrate processing chambers to increase the system throughput. In one embodiment, a system is configured to perform a substrate processing sequence that contains batch processing chambers only, or batch and single substrate processing chambers, to optimize throughput and minimize processing defects due to exposure to a contaminating environment. In one embodiment, a batch processing chamber is used to increase the system throughput by performing a process recipe step that is disproportionately long compared to other process recipe steps in the substrate processing sequence that are performed on the cluster tool. In another embodiment, two or more batch chambers are used to process multiple substrates using one or more of the disproportionately long processing steps in a processing sequence. Aspects of the invention also include an apparatus and method for delivering a precursor to a processing chamber so that a repeatable ALD or CVD deposition process can be performed. | 07-08-2010 |
| 20110056546 | THIN ABSORBER LAYER OF A PHOTOVOLTAIC DEVICE - Methods and apparatus are provided for converting electromagnetic radiation, such as solar energy, into electric energy with increased efficiency when compared to conventional solar cells. In one embodiment of a photovoltaic (PV) device, the PV device generally includes an n-doped layer and a p | 03-10-2011 |
| 20110073152 | MIXED WIRING SCHEMES FOR SHADING ROBUSTNESS - A method and apparatus for electrical interconnections utilized in devices adapted to capture solar energy, such as solar cells, solar panels and/or solar arrays is described. In one embodiment, a solar panel is described. The solar panel includes a first plurality of solar devices positioned in a center of the solar panel in electrical communication with a first circuit, and a second plurality of solar devices surrounding the first plurality of solar devices, the second plurality of solar devices in electrical communication with a second circuit, the second circuit being different than the first circuit. | 03-31-2011 |

| 20080288545 | Method and System for Forming a Keyword Database for Referencing Physical Locations - An improved method and system for specifying physical locations when using applications run on navigation systems or other computer platforms that provide navigation- or map-related functions. When requesting a navigation- or map-related function from such an application, a user specifies a physical location using a keyword instead of specifying the physical location conventionally, such as by street address. A keyword database relates keywords to physical locations. The application uses the keyword database, or a copy thereof, to find data indicating the physical location associated with the keyword specified by the user. Preferably, physical locations are defined in the keyword database in terms of data in a corresponding geographic database. The application then performs the requested navigation- or map-related function using the data indicating the physical location associated with the keyword. The keyword database is built using input from users. An on-line system is provided that users can access to associate keywords with physical locations. A user accessing the on-line system is presented with a map from which a physical location can be selected. A keyword, which may be selected by the user, is associated with the selected physical location. The keyword is stored in the keyword database along with data indicating the associated physical location. | 11-20-2008 |

| 20100042557 | TECHNIQUES FOR LOCATING AND OPERATING GASIFICATION PLANT HAVING PREDOMINATELY SCRAP TIRE RUBBER AS FEEDSTOCK - A parcel of land on which to site the plant is identified. The parcel of land is located such that about 3,500,000 to about 7,500,000 scrap tires per year are available for substantially regular and substantially continuous delivery to the plant, at a tipping fee of at least about $40.00 per ton. The plant is located on the parcel of land. One or more of synthesis gas, electricity, and steam produced by the plant are sold. | 02-18-2010 |

| 20110301342 | APPARATUS AND PROCESS FOR PURIFICATION OF PROTEINS - The invention is directed to an apparatus and method for purifying a protein. The apparatus involves the use of a capture chromatography resin, a depth filter arranged after the capture chromatography resin, and a mixed-mode chromatography resin arranged after the depth filter. The method involves providing a sample containing the protein, processing the sample through a capture chromatography resin, a depth filter, and a mixed-mode chromatography resin. A membrane adsorber or monolith may be substituted for the mixed-mode chromatography column. | 12-08-2011 |

| 20100319769 | PROCESSES FOR FABRICATING ALL-BACK-CONTACT HETEROJUNCTION PHOTOVOLTAIC CELLS - Processes for fabricating back contacts for photovoltaic cell devices are disclosed. The processes involve depositing a passivation layer on the back surface of a wafer, depositing an emitter layer on the passivation layer, depositing a metal layer on the emitter layer, laser firing selected areas of the metal layer to form base contacts, laser cutting the metal layer to create at least one isolation region between emitter contacts and base contacts, and applying a stream of reactive gas to form a second passivation layer in the isolation region. The process may further involve inkjetting a resist on the passivation layer in a pattern corresponding to a boundary between the one or more emitter contacts and the one or more base contacts, and laser cutting the metal layer over the resist to create the isolation region. | 12-23-2010 |
