Abstract:
Methods and apparatus for processing substrates are provided. In some embodiments, methods of processing substrates includes: (a) providing a process gas comprising a polymer-forming gas and an etching gas between a first electrode and a second electrode within the processing volume, wherein the first electrode is opposite the second electrode; (b) applying a first voltage waveform from a first RF power source to the second electrode to form a plasma from the process gas, wherein the plasma has a first ion energy to deposit a polymer layer directly atop a dielectric layer of the substrate; and (c) adjusting the first voltage waveform to a second voltage waveform to increase an ion energy of the plasma from the first ion energy to a second ion energy, wherein the plasma at the second ion energy ceases to deposit the polymer layer and proceeds to etch the polymer layer and the dielectric layer.

Abstract:
A virtual cathode deposition apparatus utilises virtual plasma cathode for generation of high density electron beam to ablate a solid target. A high voltage electrical pulse ionizes gas to produce a plasma which temporarily appears in front of the target and serves as the virtual plasma cathode at the vicinity of target. This plasma then disappears allowing the ablated target material in a form of a plasma plume to propagate toward the substrate. Several virtual cathodes operating in parallel provide plumes that merge into a uniform plasma which when condensing on a nearby substrate leads to wide area deposition of a uniform thickness thin film.

The present invention fills these needs by providing a distributed multi-zone plasma source. It should be appreciated that the present invention can be implemented in numerous ways, including as a process, an apparatus, a system, computer readable media, or a device. Several inventive embodiments of the present invention are described below. One embodiment provides a processing chamber including multiple plasma sources in a process chamber top. Each one of the plasma sources is a ring plasma source including a primary winding and multiple ferrites. Multiple plasma chamber outlets can couple a plasma chamber of each one of the plasma sources to the process chamber.
Abstract:
A plasma processing system having a plasma processing chamber configured for processing a substrate is provided. The plasma processing system includes at least an upper electrode and a lower electrode for processing the substrate. The substrate is disposed on the lower electrode during plasma processing, where the upper electrode and the substrate forms a first gap. The plasma processing system also includes an upper electrode peripheral extension (UE-PE). The UE-PE is mechanically coupled to a periphery of the upper electrode, where the UE-PE is configured to be non-coplanar with the upper electrode. The plasma processing system further includes a cover ring. The cover ring is configured to concentrically surround the lower electrode, where the UE-PE and the cover ring forms a second gap.
Abstract:
Apparatuses are provided for controlling flow conductance of plasma formed in a plasma processing apparatus that includes an upper electrode opposite a lower electrode to form a gap therebetween. The lower electrode is adapted to support a substrate and coupled to a RF power supply. Process gas injected into the gap is excited into the plasma state during operation. The apparatus includes a ground ring that concentrically surrounds the lower electrode and has a set of slots formed therein, and a mechanism for controlling gas flow through the slots.
