20170287791 · 2017-10-05 ·

Described herein are architectures, platforms and methods for acquiring optical emission spectra from an optical emission spectroscopy system by flowing a dry cleaning gas into a plasma processing chamber of the plasma processing system and igniting a plasma in the plasma processing chamber to initiate the waferless dry cleaning process.

Controlling dry etch process characteristics using waferless dry clean optical emission spectroscopy

Described herein are architectures, platforms and methods for acquiring optical emission spectra from an optical emission spectroscopy system by flowing a dry cleaning gas into a plasma processing chamber of the plasma processing system and igniting a plasma in the plasma processing chamber to initiate the waferless dry cleaning process.

Decoking process

In chemical processes for cracking hydrocarbons, reactors are subject to coking. This results in carburization of the metal substrate for the reactor leading to a reduced reactor life. If the reactor is subject to a decoke process, followed by a steam scour and nitriding there is a reduced tendency to carburization of the metal substrate improving the reactor life.

Aluminum fluoride mitigation by plasma treatment

Implementations described herein generally relate to methods and apparatus for in-situ removal of unwanted deposition buildup from one or more interior surfaces of a semiconductor substrate-processing chamber. In one implementation, the method comprises forming a reactive fluorine species from a fluorine-containing cleaning gas mixture. The method further comprises delivering the reactive fluorine species into a processing volume of a substrate-processing chamber. The processing volume includes one or more aluminum-containing interior surfaces having unwanted deposits formed thereon. The method further comprises permitting the reactive fluorine species to react with the unwanted deposits and aluminum-containing interior surfaces of the substrate-processing chamber to form aluminum fluoride. The method further comprises exposing nitrogen-containing cleaning gas mixture to in-situ plasma to form reactive nitrogen species in the processing volume. The method further comprises permitting the reactive nitrogen species to react with the ammonium fluoride to convert the aluminum fluoride to aluminum nitride.
