Abstract:
A system, method, and apparatus for processing substrates. A plasma processing system includes a processing chamber having a chamber body having walls with a first material enclosing an interior volume. The plasma processing system further includes a plasma source designed to expose a substrate disposed within the processing chamber to plasma related fluxes. The first material has a first set of recombination coefficients associated with the plasma related fluxes. The plasma processing system further includes a second material disposed along a first region of the chamber body, the first material having a second set of plasma recombination coefficients associated with the plasma related fluxes. The second set of plasma recombination coefficients is different that the first set of plasma recombination coefficients.
Abstract:
Semiconductor devices and methods of forming semiconductor devices are described. A method of forming metal silicon nitride films is disclosed. Some embodiments of the disclosure provide a process using ammonia plasma for treating a metal silicide or metal film to form a metal silicon nitride film. The ammonia plasma treatment generates NH* radicals that diffuse through the metal silicide to form a metal silicon nitride film that is substantially free of silicon nitride (SiN). The metal silicon nitride films have improved resistance relative to films deposited by thermal processes or plasma processes with a nitrogen plasma exposure.

Semiconductor devices suitable for narrow pitch applications and methods of fabrication thereof are described herein. In some embodiments, a semiconductor device may include a floating gate having a first width proximate a base of the floating gate that is greater than a second width proximate a top of the floating gate. In some embodiments, a method of shaping a material layer may include (a) oxidizing a surface of a material layer to form an oxide layer at an initial rate; (b) terminating formation of the oxide layer when the oxidation rate is about 90% or below of the initial rate; (c) removing at least some of the oxide layer by an etching process; and (d) repeating (a) through (c) until the material layer is formed to a desired shape. In some embodiments, the material layer may be a floating gate of a semiconductor device.

A method of selectively and conformally doping semiconductor materials is disclosed. Some embodiments utilize a conformal dopant film deposited selectively on semiconductor materials by thermal decomposition. Some embodiments relate to doping non-line of sight surfaces. Some embodiments relate to methods for forming a highly doped crystalline semiconductor layer.

Methods for filling a substrate feature with a seamless gap fill are described. Methods comprise forming a metal film a substrate surface, the sidewalls and the bottom surface of a feature, the metal film having a void located within the width of the feature; treating the metal film with a plasma; and annealing the metal film to remove the void.
Abstract:
Embodiments of the present disclosure generally relate to inductively coupled plasma sources, plasma processing apparatus, and independent temperature control of plasma processing. In at least one embodiment, a method includes introducing a process gas into a gas injection channel and generating an inductively coupled plasma within the gas injection channel. The plasma includes at least one radical species selected from oxygen, nitrogen, hydrogen, NH and helium. The method includes delivering the plasma from the plasma source to a process chamber coupled therewith by flowing the plasma through a separation grid between the plasma source and a substrate. The method includes processing the substrate. Processing the substrate includes contacting the plasma including the at least one radical species with a first side of the substrate facing the separation grid and heating the substrate using a plurality of lamps located on a second side of the substrate opposite the separation grid.
Abstract:
The present disclosure provides methods for treating film layers in a substrate including positioning the substrate in a processing volume of a processing chamber. The substrate can have high aspect ratio features extending a depth from a substrate surface to a bottom surface. The feature can have a width defined by a first sidewall and a second sidewall. A film with a composition that includes metal is formed on the substrate surface and the first sidewall, the second sidewall, and the bottom surface of each feature. The film in the feature can have a seam extending substantially parallel to the first and second sidewalls. The film is annealed and exposed to an oxygen radical while converting the metal of the film to a metal oxide. The metal oxide is exposed to a hydrogen radical while converting the metal oxide to a metal fill layer.
