    Abstract: A method and apparatus for calibration non-contact temperature sensors within a process chamber are described herein. The calibration of the non-contact temperature sensors includes the utilization of a band edge detector to determine the band edge absorption wavelength of a substrate. The band edge detector is configured to measure the intensity of a range of wavelengths and determines the actual temperature of a substrate based off the band edge absorption wavelength and the material of the substrate. The calibration method is automated and does not require human intervention or disassembly of a process chamber for each calibration.

    Abstract: Embodiments herein relate to chamber liners with a multi-piece design for use in processing chambers. The multi-piece design can have an inner portion and an outer portion. A portion of the inner surface of the outer portion may be designed to be in contact with the outer surface of the inner portion at a single junction point, creating a thermal barrier between the inner portion and outer portion, thus reducing heat transfer from the inner portion and outer portion. The thermal barrier creates higher temperatures at the chamber liner inner surface and therefore leads to shorter heat up times within the chamber. Additionally, the thermal barrier also creates lower temperatures near the base ring and outer surface of the outer ring, thereby protecting the chamber walls and requiring less thermal regulation/dissipation at the chamber walls.

    Abstract: Methods and apparatus for deposition processes are provided herein. In some embodiments, an apparatus may include a substrate support including a susceptor plate having a pocket disposed in an upper surface of the susceptor plate and having a lip formed in the upper surface and circumscribing the pocket, the lip configured to support a substrate on the lip; and a plurality of vents extending from the pocket to the upper surface of the susceptor plate to exhaust gases trapped between the backside of the substrate and the pocket when a substrate is disposed on the lip. Methods of utilizing the inventive apparatus for depositing a layer on a substrate are also disclosed.

    Abstract: Embodiments described herein generally relate to apparatus for fabricating semiconductor devices. A gas injection apparatus is coupled to a first gas source and a second gas source. Gases from the first gas source and second gas source may remain separated until the gases enter a process volume in a process chamber. A coolant is flowed through a channel in the gas injection apparatus to cool the first gas and the second gas in the gas injection apparatus. The coolant functions to prevent thermal decomposition of the gases by mitigating the influence of thermal radiation from the process chamber. In one embodiment, the channel surrounds a first conduit with the first gas and a second conduit with the second gas.
