  • Patent number: 11810766
    Abstract: Embodiments of the present disclosure are directed towards a protective multilayer coating for process chamber components exposed to temperatures from about 20° C. to about 300° C. during use of the process chamber. The protective multilayer coating comprises a bond layer and a top layer, the bond layer is formed on a chamber component to reduce the stress between the top layer and the chamber component. The reduced stress decreases or prevents particle shedding from the top layer of the multilayer coating during and after use of the process chamber. The bond layer comprises titanium, titanium nitride, aluminum, or combinations thereof, and the top layer comprises tungsten nitride.

  • Patent number: 11807931
    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.

  • Publication number: 20230282454
    Abstract: Processing chambers, substrate supports and thermal shields are described. A thermal shield comprises a disc-shaped body having a thickness, an outer diameter with a first edge and a second edge at opposite ends of a diameter of the disc-shaped body, a front surface and a back surface defining the thickness. The front surface has a first longitudinal region comprising the first edge and a second longitudinal region comprising the second edge. Coating one or more of the first longitudinal region or the second longitudinal region with an emissivity material (i.e., emissivity) reduces side to side temperature variation. In some embodiments, processing chambers having the thermal shield described herein consume less power than comparative processing chambers that do not include a thermal shield.
