  • Publication number: 20220415676
    Abstract: Embodiments of gas distribution modules for use with rapid thermal processing (RTP) systems and methods of use thereof are provided herein. In some embodiments, a gas distribution module for use with a RTP chamber includes: a first carrier gas line and a first liquid line fluidly coupled to a mixer, the mixer having one or more control valves configured to mix a carrier gas from the first carrier gas line and a liquid from the first liquid line in a desired ratio to form a first mixture; a vaporizer coupled to the mixer and configured to receive the first mixture in a hollow internal volume, the vaporizer having a heater configured to vaporize the first mixture; and a first gas delivery line disposed between the vaporizer and the RTP chamber to deliver the vaporized first mixture to the RTP chamber.

  • Publication number: 20210249284
    Abstract: A substrate support pedestal connectable to a shaft includes a thermally conductive body, a first fluid channel disposed within an outer zone of the thermally conductive body, and a second fluid channel disposed within an inner zone of the thermally conductive body. The first fluid channel and the second fluid channel are not in fluid communication with each other and are thermally isolated from each other by a thermal barrier within the substrate support channel.

  • Patent number: 10458861
    Abstract: Embodiments disclosed herein relate to a thermal processing chamber having a substrate monitoring system. In one embodiment, a temperature monitoring system is disclosed herein. The temperature monitoring system includes a housing and a window defining an interior volume. The temperature monitoring system further includes two or more light sources, a camera, and a polarizer. The two or more light sources are disposed in the interior volume, beneath the window. A first light source of the two or more light sources has a first wavelength. A second light source of the two or more light sources has a second wavelength. A camera is disposed opposite the two or more light sources. The camera to captures a plurality of frames of two or more light beams received from the two or more light sources. The polarizer disposed in an optical path of the two or more light beams.
