Abstract:
Embodiments of showerheads having a detachable gas distribution plate are provided herein. In some embodiments, a showerhead for use in a semiconductor processing chamber may include a body having a first side and a second side opposing the first side; a gas distribution plate disposed proximate the second side of the body, wherein the gas distribution plate is formed from a material having an electrical resistivity between about 60 ohm-cm to 90 ohm-cm; a clamp disposed about a peripheral edge of the gas distribution plate to removably couple the gas distribution plate to the body; and a thermal gasket disposed in a gap between the body and gas distribution plate.

Claim (Index 11):
A process chamber, comprising:\n a chamber body having a substrate support disposed within an inner volume of the chamber body; and a showerhead disposed within the inner volume of the chamber body opposite the substrate support, the showerhead comprising:\n a body having a first side and a second side opposing the first side, wherein the first side of the body is coupled to a component of the process chamber; \n a gas distribution plate disposed proximate the second side of the body, wherein the gas distribution plate is formed from a material having an electrical resistivity between about 60 ohm-cm to 90 ohm-cm; \n a clamp disposed about a peripheral edge of the gas distribution plate to removably couple the gas distribution plate to the body; and \n a thermal gasket disposed in a gap between the body and gas distribution plate.
