SUBSTRATE PROCESSING TOOL SHOWERHEAD
First Claim
1. A substrate processing tool comprising:
- a housing defining a processing chamber;
a substrate support coupled to the housing and configured to support a substrate within the processing chamber; and
a showerhead coupled to the housing and positioned within the processing chamber above the substrate support, the showerhead comprising a dielectric material and having a first surface with a plurality of fluid outlets thereon, a second surface with a plurality of fluid ports thereon, a first passageway extending through the showerhead and in fluid communication with one or more of the plurality of fluid outlets and a first of the fluid ports, and a second passageway extending within the showerhead and in fluid communication with a second and a third of the plurality of fluid ports.

Abstract
Embodiments provided herein describe substrate processing tools and showerheads. A substrate processing tool includes a housing defining a processing chamber. A substrate support is coupled to the housing and configured to support a substrate within the processing chamber. A showerhead is coupled to the housing and positioned within the processing chamber above the substrate support. The showerhead includes a dielectric material and has a first surface with a plurality of fluid outlets, a second surface with a plurality of fluid ports, and first and second passageways extending therethrough. The first passageway is in fluid communication with the plurality of fluid outlets and a first of the plurality of fluid ports. The second passageway is in fluid communication with a second and a third of the fluid ports.

11. A showerhead for a substrate processing tool comprising:
-
a body having an upper surface and a lower surface and comprising a dielectric material, the body further comprising a first passageway extending through the body and operable to deliver a first processing fluid and in fluid communication with at least one fluid outlet on the lower surface of the body, and in fluid communication with a first of a plurality of fluid ports on the upper surface of the body, and a second passageway extending within the body and operable to deliver coolant fluid and in fluid communication with a second and a third of the plurality of fluid ports on the upper surface of the body, wherein the first passageway is not in fluid communication with the second passageway. - View Dependent Claims (12, 13, 14, 15)
