Abstract:
Reactor systems having an external pressure balancer device to counter-balance the hydrostatic end force of one or more system chambers are disclosed.
Abstract:
A system for degassing granular polysilicon includes a baking container having an interior space for containing granular polysilicon. The system also includes a heat source for heating the granular polysilicon within the interior space of the baking container. The system further includes a drive mechanism operatively connected to the baking container for mechanically agitating the granular polysilicon within the interior space during heating.
Abstract:
A method of retrofitting an existing wire saw that includes loose abrasive to a replacement including a fixed abrasive wire includes removing an existing wire spool traverser, installing a replacement new wire spool traverser (330) including two guide rollers (340) connected to at least one load cell that measures strain on the two guide rollers (340) caused by a wire (310) passing between the two guide rollers (340), and installing a wire positioning system (342) configured to position the wire away from a shoulder of at least one existing directional pulley (220) of the existing wire saw.
Abstract:
A solar module system includes a frame, a microinverter, and an adapter assembly for connecting the microinverter to the frame. The frame includes a body, a mounting flange extending from a bottom of the body at an edge, and a cable management flange extending from an interior surface of the body. The cable management flange and the mounting flange define a cable cavity therebetween for retaining at least one cable. The adapter assembly includes an adapter including a microinverter attachment projection coupled to the microinverter, a frame attachment extension, and a side wall extending therebetween.
Abstract:
Production of silicon ingots in a crystal puller that involve reduction of the erosion rate at the crucible contact point are disclosed. The method comprises introducing a dopant selected from the group consisting of indium, gallium, thallium, arsenic, antimony into the silicon melt to alter the oxygen evaporation profile of the melt; and withdrawing a silicon ingot from the doped melt, the atmosphere being at a pressure of at least about 5 kPa while withdrawing the silicon ingot.
Abstract:
Clamping assemblies for sealing an annular chamber and reaction chamber of a reactor system are disclosed. The clamping assemblies may include actuators that are symmetrically arranged in two or more independently controllable groups of actuators.
Abstract:
Methods for separating halosilanes that involve use of a distillation column having a partition that divides the column into portions for producing three product fractions are disclosed. Methods and systems for producing silane by disproportionation of halosilanes that use such columns and methods for producing polycrystalline silicon are also disclosed.
Abstract:
Apparatus and processes for preparing heterostructures with reduced strain are disclosed. The heterostructures may include a semiconductor structure that conforms to a surface layer having a different crystal lattice constant than the structure to form a relatively low-defect heterostructure.
Abstract:
A gas decomposition reactor for the decomposition of a gas into a mixture of solid and gaseous by-products is disclosed. The gas decomposition reactor includes a reactor vessel, a Raman spectrometer, and a processor. The reactor vessel has an inlet for receiving inlet gas and an exhaust outlet for releasing exhaust gas. The Raman spectrometer is connected with the exhaust outlet for determining a chemical conversion within the reactor chamber and generating a corresponding signal. The processor is connected with the Raman spectrometer to receive the signal from the Raman spectrometer. The processor is capable of comparing the signal with a set of values and calculating differences between the signal and the set of values. The processor is connected with the inlet to regulate a flow of the inlet gas.
