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:
The disclosure pertains to a capacitively coupled plasma source in which VHF power is applied through an impedance-matching coaxial resonator having a symmetrical power distribution.
Abstract:
A plasma reactor that generates plasma in a workpiece processing chamber by an electron beam, has an electron beam source and segmented suppression electrode with individually biased segments to control electron beam density distribution.
Abstract:
The present invention generally comprises a showerhead insulator for electrically isolating a showerhead assembly from a processing chamber wall, a chamber liner assembly for lining a processing chamber, a lower chamber liner for lining an evacuation area of a processing chamber, and a flow equalizer for ensuring a uniform evacuation of a processing chamber. When processing a substrate within an etching chamber, the showerhead needs to be electrically isolated from ground. A showerhead insulator may insulate the showerhead from ground while also preventing plasma from entering the volume that it occupies. A chamber liner may protect the chamber walls from contamination and reduce chamber cleaning. A flow equalizer will permit processing gases to be evenly pulled into the evacuation channel rather than a disproportionate flow into the evacuation channel. A lower liner can aid in uniformly drawing the vacuum and protecting the chamber walls from contamination.
