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.

Chamber injector

Disclosed are embodiments for an engineered feature formed as a part of or on a chamber component. In one embodiment, a chamber component for a processing chamber includes a component part body having unitary monolithic construction. The component part body has an outer surface. An engineered complex surface is formed on the outer surface. The engineered complex surface has a first lattice framework formed from a plurality of first interconnected laths and a plurality of first openings are bounded by three or more laths of the plurality of laths.

Lattice coat surface enhancement for chamber components

Processing chamber components and methods of manufacture of same are provided herein. In some embodiments, a component part body includes a component part body having a base plane and at least one textured surface region, wherein the at least one textured surface region comprises a plurality of independent surface features having a first side having at least a 45 degree angle with respect to the base plane. In at least some embodiments, the textured surface includes a plurality of independent surface features which are pore free.
