Abstract:
Processes for producing polycrystalline silicon by thermal decomposition of silane are disclosed. The processes generally involve thermal decomposition of silane in a fluidized bed reactor operated at reaction conditions that result in a high rate of productivity relative to conventional production processes.

Abstract:
Processes and systems for purifying silane-containing streams and, in particular, for purifying silane-containing streams that also contain ethylene are disclosed. The processes and systems may be arranged such that one or more ethylene reactors are downstream of light-end distillation operations.
Abstract:
Methods and systems for producing silane that use electrolysis to regenerate reactive components therein are disclosed. The methods and systems may be substantially closed-loop with respect to halogen, an alkali or alkaline earth metal and/or hydrogen.
Abstract:
A liner assembly for a substrate processing system includes a first liner and a second liner. The first liner includes an annular body and an outer peripheral surface including a first fluid guide. The first fluid guide is curved about a circumferential line extending around the first liner. The second liner includes an annular body, an outer rim, an inner rim, a second fluid guide extending between the outer rim and the inner rim, and a plurality of partition walls extending outwardly from the second fluid guide. The second fluid guide is curved about the circumferential line when the first and second liners are positioned within the processing system.
Abstract:
A computing device is configured to execute a first instance of a single-threaded script engine in a first thread associated with a first execution context, wherein the first instance of the single-threaded script engine accesses at least one shared script object through a first reference counted script base value object. The computing device is also configured to concurrently execute a second instance of the single-threaded script engine in a second thread_associated with a second execution context, wherein the second instance of the single-threaded script engine accesses the at least one shared script object through a second reference counted script base value object. The script engine does not switch between the execution contexts.
Abstract:
A system for preventing an unsafe operation of at least one machine communicatively coupled to a computing device. The system includes the computing device which includes a processor coupled to a memory. The memory contains processor-executable instructions that, when executed, cause the computing device to perform the steps of storing, in the memory, a first state of a first machine of the at least one machine, generating a first pending output to be issued to the first machine, determining whether an unsafe condition would result if the first pending output is issued to the first machine in the first state, and issuing the first pending output upon determining that issuing the first pending output would not result in an unsafe condition and blocking the first pending output from being issued upon determining that issuing the first pending output would result in an unsafe condition.
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 dopant funnel for loading dopant pellets into a dispenser tube of a dopant dispenser is disclosed. The dopant funnel has a cup connected through a restrictor to a shaft. The cup holds random oriented dopant pellets. The restrictor meters the amount and orientation of dopant pellets being removed from the cup. The shaft is in alignment with the restrictor for delivering dopant pellets from the cup to the dispenser tube.
Abstract:
A platen for polishing a surface of a wafer has a reaction plate, a polishing plate, and a bladder. The reaction plate has a top and bottom surface, and defines a longitudinal axis. The polishing plate is positioned coaxially with the reaction plate. The polishing plate has a second top surface and a second bottom surface. The second top surface is adjacent to the bottom surface of the reaction plate. The bladder is coaxially located along a radially outer portion of either the top or bottom surface of the reaction plate. The bladder is connected with the polishing plate and able to expand to deform the polishing plate with respect to the bottom surface of the reaction plate.
