20100159132 | Linear Deposition Source - A deposition source includes a plurality of crucibles that each contains a deposition material. A heat shield provides at least partial thermal isolation for at least one of the plurality of crucibles. A body is included with a plurality of conductance channels. An input of each of the plurality of conductance channels is coupled to an output of a respective one of the plurality of crucibles. A heater increases a temperature of the plurality of crucibles so that each crucible evaporates the deposition material into the plurality of conductance channels. An input of each of a plurality of nozzles is coupled to an output of one of the plurality of conductance channels. Evaporated deposition materials are transported from the crucibles through the conductance channels to the nozzles where the evaporated deposition material is ejected from the plurality of nozzles to form a deposition flux. | 06-24-2010 |
20100282167 | Linear Deposition Source - A deposition source includes a crucible for containing deposition material and a body comprising a conductance channel. An input of the conductance channel is coupled to an output of the crucible. A heater heats the crucible so that the crucible evaporates the deposition material into the conductance channel. A heat shield comprising a plurality of heat resistant material layers is positioned around at least one of the heater and the body. A plurality of nozzles is coupled to an output of the conductance channel so that evaporated deposition material is transported from the crucible through the conductance channel to the plurality of nozzles where the evaporated deposition material is ejected from the plurality of nozzles to form a deposition flux. | 11-11-2010 |
20100285218 | Linear Deposition Source - A deposition source includes at least one crucible for containing deposition material. A body includes a conductance channel with an input coupled to an output of the crucible. A heater increases a temperature of the crucible so that the crucible evaporates the deposition material into the conductance channel. A plurality of nozzles is coupled to an output of the conductance channel so that evaporated deposition material is transported from the crucible through the conductance channel to the plurality of nozzles where the evaporated deposition material is ejected from the plurality of nozzles to form a deposition flux. At least one of the plurality of nozzles includes a tube that is positioned proximate to the conductance channel so that the tube restricts an amount of deposition material supplied to the nozzle including the tube. | 11-11-2010 |

20080225926 | IN SITU OPTICAL SURFACE TEMPERATURE MEASURING TECHNIQUES AND DEVICES - A vacuum processing chamber for measuring the temperature of a surface of an object comprising a cap is provided. The cap has a non-deformable end wall of thermally conducting material and a side wall connected thereto. An outside surface of the end wall is shaped to conform to a shape of the object surface to be measured. A surface on an inside of the end wall of the cap emits electromagnetic radiation having a detectable optical characteristic that is proportional to the temperature of the cap end wall. The vacuum processing chamber further comprises a light wave guide having one end held within the cap a distance from the radiation emitting element and in optical communication therewith. | 09-18-2008 |
20080283110 | LARGE SCALE ARRAY OF THERMOELECTRIC DEVICES FOR GENERATION OF ELECTRIC POWER - A thermoelectric power generating device is assembled from multiple thermoelectric elements disposed in a chip structure, the chip structure forming a power generating core. Multiple cores are stacked within a thermal container such that thermal energy provided at a first end of the thermal container is delivered in a serial manner to the stacked cores. The thermal container includes heat absorbers, heat reflectors and heat transmission barriers so that minimal thermal energy is lost through the walls of the container and maximum thermal energy flows from the heat source through and past the cores to an ambient temperature end of the container so as to create a controlled temperature differential from the hot end to the cooler end of the container as well as across each core stacked therein. The temperature differential across each core results in the generation of electrical energy, such electrical energy being collected by standard power utilization techniques. | 11-20-2008 |
