摘要:
An apparatus to isolate a rotating frame in a processing chamber, comprising: a support cylinder rotatably extending from the rotating frame; and a co-rotating edge ring extension extending from the support cylinder to at least one of substantially thermally, optically and mechanically isolate the region above the co-rotating edge ring extension from the region below the co-rotating edge ring extension.
摘要:
A method for controlling the temperature of a substrate in a processing chamber. The processing chamber employs a heating control over at least two heating zones. Each heating zone is independently controllable according to a measured signal corresponding to the substrate temperature and a user-definable offset.

In one embodiment, the invention is directed to an apparatus for preventing depositions from occurring on a reflector in a processing chamber, comprising: a cover disposed adjacent to the reflector, the cover optically transparent over a range of wavelengths in which the reflector is reflective; and at least one cover support for maintaining the position of the cover relative to the reflector.
摘要:
An apparatus for purging the backside of a substrate in a process chamber includes a purge gas injector. The injector includes a substantially annular-shaped opening providing a slit that is structured and arranged to direct a flow of purge gas about radially outward therefrom in a direction approximately parallel to a plane defined by the substrate, wherein the substrate is supported in the process chamber above the purge gas injector. When the substrate is rotated at a sufficient speed, the purge gas flowing from the injector is impelled to flow spirally outward along the backside of the substrate.

A substrate support, for example an edge ring, includes an upper ledge for supporting a first substrate, such as a semiconductor wafer, during a first process, and a lower ledge contiguous with the upper ledge for supporting a second substrate during a second process for cleaning the substrate support. A method of processing substrates supported by the edge ring in a thermal process chamber is also disclosed.
摘要:
Methods for forming photoresists sensitive to radiation on a substrate are provided. Described are chemical vapor deposition methods of forming films (e.g., silicon-containing films) as photoresists using a plasma which may be exposed to radiation to form a pattern. The deposition methods utilize precursors with cross-linkable moieties that will cross-link upon exposure to radiation. Radiation may be carried out in the with or without the presence of oxygen. Exposed or unexposed areas may then be developed in an aqueous base developer.
摘要:
A method and apparatus for providing a precursor to a process chamber is described. The apparatus comprises an ampoule capable of receiving either a liquid precursor source material or a solid precursor source material. The ampoule is capable of delivering either a liquid precursor material to a vaporizer coupled to the process chamber, or a vaporized or gaseous precursor material to the process chamber. The ampoule also includes a continuous level sensor to accurately monitor the level of precursor source material within the ampoule.
摘要:
Methods for forming photoresists sensitive to radiation on substrate are provided. Atomic layer deposition methods of forming films (e.g., silicon-containing films) photoresists are described. The process can be repeated multiple times to deposit a plurality of silicon photoresist layers. Process of depositing photoresist and forming patterns in photoresist are also disclosed which utilize carbon containing underlayers such as amorphous carbon layers.
摘要:
Provided are methods of depositing hafnium or zirconium containing metal alloy films. Certain methods comprise sequentially exposing a substrate surface to alternating flows of an organometallic precursor and a reductant comprising M(BH4)4 to produce a metal alloy film on the substrate surface, wherein M is selected from hafnium and zirconium, and the organometallic precursor contains a metal N. Gate stacks are described comprising a copper barrier layer comprising boron, a first metal M selected from Hf and Zr, and a second metal N selected from tantalum, tungsten, copper, ruthenium, rhodium, cobalt and nickel; and a copper layer overlying the copper barrier seed layer.
摘要:
Provided are low temperature methods of depositing hafnium or zirconium containing films using a Hf(BH4)4 precursor, or Zr(BH4)4 precursor, respectively, as well as a co-reactant. The co-reactant can be selected to obtain certain film compositions. Co-reactants comprising an oxidant can be used to deposit oxygen into the film. Accordingly, also provided are films comprising a metal, boron and oxygen, wherein the metal comprises hafnium where a Hf(BH4)4 precursor is used, or zirconium, where a Zr(BH4)4 precursor is used.
