Abstract:
A plasma reactor has an electron beam source as a plasma source and a rotation motor coupled to rotate the workpiece support about a rotation axis that is transverse to an emission path of said electron beam source.
Abstract:
A plasma reactor has an overhead multiple coil antennas including a parallel spiral coil antenna and symmetric and radial RF feeds and cylindrical RF shielding around the symmetric and radial RF feeds. The radial RF feeds are symmetrically fed to the plasma source.
Abstract:
Embodiments of the invention include an apparatus, system, and method for cooling a pedestal for supporting a workpiece during plasma processing. An embodiment of a pedestal includes: a base over which the workpiece is to be disposed, a plurality of nozzles to supply a fluid from a supply plenum to impinge on a surface of the base, and a plurality of return conduits to return the supplied fluid to a return plenum. The fluid to be supplied by the plurality of nozzles can be projected as one or more jets submerged in surrounding fluid or as a spray that emerges from a surrounding fluid within a volume between the plurality of nozzles and the base to impinge on the surface of the base.
Abstract:
Plural sensors on an interior surface of a reactor chamber are linked by respective RF communication channels to a hub inside the reactor chamber, which in turn is linked to a process controller outside of the chamber.
Abstract:
A plasma reactor has an overhead multiple coil inductive plasma source with symmetric RF feeds and symmetrical RF shielding around the symmetric RF feeds.
Abstract:
A plasma reactor includes a window assembly, inner, middle and outer coil antennas adjacent the window assembly, inner, middle and outer current distributors respectively coupled to the inner, middle and outer coil antennas, a ceiling plate overlying the window assembly, first, second and third RF power terminals, and first, second and third axial RF power feeds connected between respective ones of the first, second and third RF power terminals and respective ones of the inner, middle and outer current distributors. The third axial RF power feed includes an outer RF power distribution cylinder surrounding the first and second RF axial power feeds. Plural spaced-apart reactance elements are electrically connected to the outer RF power distribution cylinder.
Abstract:
A plasma reactor has an overhead inductively coupled plasma source with two coil antennas and symmetric and radial RF feeds and cylindrical RF shielding around the symmetric and radial RF feeds. The radial RF feeds are symmetrically fed to the plasma source.
Abstract:
A plasma reactor enclosure has a metallic portion and a dielectric portion of plural dielectric windows supported on the metallic portion, each of the dielectric windows extending around an axis of symmetry. Plural concentric coil antennas are disposed on an external side of the enclosure, respective ones of the coil antennas facing respective ones of the dielectric windows.
Abstract:
A plasma reactor has an overhead multiple coil inductive plasma source with symmetric RF feeds and a symmetrical chamber exhaust with plural struts through the exhaust region providing access to a confined workpiece support. A grid may be included for masking spatial effects of the struts from the processing region.
Abstract:
Methods and apparatus for regulating the temperature of a component in a plasma-enhanced process chamber are provided herein. In some embodiments, an apparatus for processing a substrate includes a process chamber and an RF source to provide RF energy to form a plasma in the process chamber. A component is disposed in the process chamber so as to be heated by the plasma when formed. A heater is configured to heat the component and a heat exchanger is configured to remove heat from the component. A chiller is coupled to the heat exchanger via a first flow conduit having an on/off flow control valve disposed therein and a bypass loop to bypass the flow control valve, wherein the bypass loop has a flow ratio valve disposed therein.
