Abstract: Embodiments of the present disclosure generally relate to a process chamber for conformal oxidation of high aspect ratio structures. The process chamber includes a liner assembly located in a first side of a chamber body and two pumping ports located in a substrate support portion adjacent a second side of the chamber body opposite the first side. The liner assembly includes a flow divider to direct fluid flow away from a center of a substrate disposed in a processing region of the process chamber. The liner assembly may be fabricated from quartz minimize interaction with process gases, such as radicals. The liner assembly is designed to reduce flow constriction of the radicals, leading to increased radical concentration and flux. The two pumping ports can be individually controlled to tune the flow of the radicals through the processing region of the process chamber.

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.

Abstract: Embodiments described herein generally relate to a processing apparatus having a cover piece that participates in preheating a process gas. In one implementation, the cover piece includes an annulus. The annulus has an inner wall with a first height, an outer wall with a second height, and a top surface.
