  • Patent number: 11041253
    Abstract: A system for depositing thin single crystal silicon wafers by epitaxial deposition in a silicon precursor depletion mode with cross-flow deposition may include: a substrate carrier with low total heat capacity, high emissivity and small volume; a lamp module with rapid heat-up, efficient heat production, and spatial control over heating; and a manifold designed for cross-flow processing. Furthermore, the substrate carrier may include heat reflectors to control heat loss from the edges of the carrier and/or heat chokes to thermally isolate the carrier from the manifolds, allowing independent temperature control of the manifolds. The carrier and substrates may be configured for deposition on both sides of the substrates—the substrates having release layers on both sides and the carriers being configured to have equal process gas flow over both surfaces of the substrate. High volume may be addressed by a deposition system comprising multiple mini-batch reactors.

  • Patent number: 9920451
    Abstract: An epitaxial reactor enabling simultaneous deposition of thin films on a multiplicity of wafers is disclosed. During deposition, a number of wafers are contained within a wafer sleeve comprising a number of wafer carrier plates spaced closely apart to minimize the process volume. Process gases flow preferentially into the interior volume of the wafer sleeve, which is heated by one or more lamp modules. Purge gases flow outside the wafer sleeve within a reactor chamber to minimize deposition on the chamber walls. Sequencing of the illumination of the individual lamps in the lamp module may further improve the linearity of variation in deposition rates within the wafer sleeve. To improve uniformity, the direction of process gas flow may be varied in a cross-flow configuration. Combining lamp sequencing with cross-flow processing in a multiple reactor system enables high throughput deposition with good film uniformities and efficient use of process gases.

  • Publication number: 20150361555
    Abstract: A CVD reactor for depositing material on substrates may comprise: a vacuum chamber; at least two substrate carriers arranged in parallel in a row within the vacuum chamber, each of the at least two substrate carriers comprising mounting positions for a plurality of substrates, the mounting positions being on the walls of channels configured for flowing process gases, the channels being in parallel planes within all of the at least two substrate carriers; a planar electrically resistive heater between every two adjacent substrate carriers in the row; and planar heaters at both ends of the row. Furthermore, CVD reactor chambers with three channel substrate carriers and/or gas preheat structure are described herein.
