A method and apparatus for processing a substrate are provided. The apparatus includes a pedestal and rotation member, both of which are moveably disposed within a processing chamber. The rotation member is adapted to rotate a substrate disposed in the chamber. The substrate may be supported by an edge ring during processing. The edge ring may selectively engage either the pedestal or the rotation member. In one embodiment, the edge ring engages the pedestal during a deposition process and the edge ring engages the rotation member during rotation of the substrate. The rotation of the substrate during processing may be discrete or continuous.

A method and apparatus for cleaning a process chamber are provided. In one embodiment, a process chamber is provided that includes a remote plasma source and a process chamber having at least two processing regions. Each processing region includes a substrate support assembly disposed in the processing region, a gas distribution system configured to provide gas into the processing region above the substrate support assembly, and a gas passage configured to provide gas into the processing region below the substrate support assembly. A first gas conduit is configured to flow a cleaning agent from the remote plasma source through the gas distribution assembly in each processing region while a second gas conduit is configured to divert a portion of the cleaning agent from the first gas conduit to the gas passage of each processing region.
Abstract:
A method of processing a substrate according to a PECVD process is described. Temperature profile of the substrate is adjusted to change deposition rate profile across the substrate. Plasma density profile is adjusted to change deposition rate profile across the substrate. Chamber surfaces exposed to the plasma are heated to improve plasma density uniformity and reduce formation of low quality deposits on chamber surfaces. In situ metrology may be used to monitor progress of a deposition process and trigger control actions involving substrate temperature profile, plasma density profile, pressure, temperature, and flow of reactants.

An apparatus for plasma processing a substrate is provided. The apparatus comprises a processing chamber, a substrate support disposed in the processing chamber, and a lid assembly coupled to the processing chamber. The lid assembly comprises a conductive gas distributor such as a face plate coupled to a power source, and a heater coupled to the conductive gas distributor. A zoned blocker plate is coupled to the conductive gas distributor and a cooled gas cap is coupled to the zoned blocker plate. A tuning electrode may be disposed between the conductive gas distributor and the chamber body for adjusting a ground pathway of the plasma. A second tuning electrode may be coupled to the substrate support, and a bias electrode may also be coupled to the substrate support.

Embodiments disclosed herein relate to a processing chamber having a lens disposed therein. In one embodiment, the processing chamber includes a chamber body, a substrate support assembly, a light source, and a lens. The chamber body defines an interior volume of the processing chamber. The interior volume has a first area and a second area. The substrate support assembly is disposed in the second area. The substrate support assembly is configured to support a substrate. The light source is disposed above the substrate support assembly in the first area. The lens is disposed between the light source and the substrate support assembly. The lens includes a plurality of features formed therein. The plurality of features is configured to preferentially direct light from the light source to an area of interest on the substrate when disposed on the substrate support assembly.
Abstract:
Magnetron configurations that provide more efficient and/or more uniform cooling characteristics and methods for forming the magnetrons are provided. The magnetron includes one or more flow directing structures disposed between parallel cooling fins. The flow directing structures direct air flow across various surfaces of the cooling fins that otherwise would be obstructed by magnetron components, reducing the incidence and/or magnitude of hot spots on the cooling fins and/or on other magnetron components. The flow directing structures also adjust flow rates to improve cooling efficiency.
Abstract:
Embodiments described herein generally relate to apparatus and methods for thermally treating chamber components for use in ultraviolet semiconductor processing chambers. Thermal treatment of chamber components comprising unitary ceramic or glass articles may reduce the probability of particle generation when the chamber components are exposed to corrosive environments, such as exposure to ultraviolet light and ozone/oxygen radicals. A method of thermally treating chamber components includes heating the unitary article at an acceptable ramp rate to a desired temperature for a desired time period and subsequently cooling the unitary article at the ramping rate.
Abstract:
A method and apparatus for a pedestal is provided. In one embodiment, the pedestal includes a body comprising a ceramic material having a flange, one or more heating elements embedded in the body, a first shaft coupled to the flange, and a second shaft coupled to the first shaft; wherein the second shaft includes a plurality of fluid channels formed therein that terminate in the second shaft.
