Embodiments of the disclosure relate to faceplates for a processing chamber. In one example, a faceplate includes a body having a plurality of apertures formed therethrough. A heating element is disposed within the body, and the heating element circumscribes the plurality of apertures. A support ring is disposed the body. The support ring circumscribes the heating element. The support ring includes a main body and a cantilever extending radially inward from the main body. The cantilever contacts the body of the faceplate.

Provided is a SiC chemical vapor deposition apparatus including: a furnace body inside of which a growth space is formed; and a placement table which is positioned in the growth space and has a placement surface on which a SiC wafer is placed, in which the furnace body comprises a first hole which is positioned on an upper portion which faces the placement surface and through which a raw material gas is introduced into the growth space, a second hole which is positioned on a side wall of the furnace body and through which a purge gas flows into the growth space, a third hole which is positioned on the side wall of the furnace body at a lower position than the second hole and discharges the gases in the growth space, and a protrusion which is protrudes towards the growth space from a lower end of the second hole to adjust a flow of the raw material gas.

Embodiments described herein generally relate to a processing system and a method of delivering a reactant gas. The processing system includes a substrate support system, an injection cone, and an intake. The injection cone includes a linear rudder. The linear rudder is disposed such that the flow of reactant gas through the injection cone results in film growth on a specific portion of a substrate. The method includes flowing the gas through the injection cone and delivering the gas onto the substrate below. The localization of the reactant gas, allows for film growth on a specific portion of the substrate.
