摘要:
A plasma reactor embodying the invention includes a wafer support and a chamber enclosure member having an interior surface generally facing the wafer support. At least one miniature gas distribution plate for introducing a process gas into the reactor is supported on the chamber enclosure member and has an outlet surface which is a fraction of the area of the interior surface of said wafer support. A coolant system maintains the chamber enclosure member at a low temperature, and the miniature gas distribution plate is at least partially thermally insulated from the chamber enclosure member so that it is maintained at a higher temperature by plasma heating.

A thermally controlled chamber liner comprising a passage having an inlet and outlet adapted to flow a fluid through the one or more fluid passages formed at least partially therein. The chamber liner may comprise a first liner, a second liner or both a first liner and a second liner. The thermally controlled chamber liner maintains a predetermined temperature by running fluid from a temperature controlled, fluid source through the fluid passages. By maintaining a predetermined temperature, deposition of films on the chamber liner is discouraged and particulate generation due to stress cracking of deposited films is minimized.

A substrate support assembly 30 comprises a substrate support 38 and a collar 130 which may comprise at least one slit 150. The slit allows for thermal expansion compensation in the support assembly 30. The collar 130 may, for example, protect the dielectric 45 from erosion in a process chamber 25. In one version, the collar 130 comprises a clamping ring 200 on the dielectric 45.

摘要:
In one aspect, a fuel cell assembly comprises a plurality of fuel cells. Each of the fuel cells includes an anode layer, a cathode layer and an electrolyte interposed therebetween. The fuel cell further comprises a conducting layer in intimate contact with at least one of the cathode layer and the anode layer. The conducting layer is configured to facilitate transport of electrons from the anode layer and the cathode layer.
摘要:
The present invention provides a temperature controlled energy transparent window or electrode used to advantage in a substrate processing system. The invention also provides methods associated with controlling lid temperature during processing and for controlling etching processes. In a preferred embodiment the invention provides a fluid supply system for the lid which allows the fluid to flow through a feedthrough and into and out of a channel formed in the window or electrode. The fluid supply system may also mount the window or electrode to a retaining ring which secures the window or electrode to the chamber. In another aspect the invention provides a bonded window or electrode having a first and second plate having a channel formed in the plates so that when the plates are bonded together they form a channel therein through which a temperature controlling fluid can be flowed. An external control system preferably regulates the temperature of the fluid.
