  • Patent number: 11107693
    Abstract: A method for removing photoresist, an oxidation layer, or both from a semiconductor substrate is disclosed. The method includes placing a substrate in a processing chamber, the processing chamber separate from a plasma chamber for generating a non-oxidizing plasma to be used in treating the substrate; generating a first non-oxidizing plasma from a first reactant gas and a first carrier gas in the plasma chamber, wherein the first non-oxidizing plasma comprises from about 10% to about 40% of the first reactant gas, wherein the first reactant gas has a flow rate of from about 100 standard cubic centimeters per minute to about 15,000 standard cubic centimeters per minute, and wherein the first carrier gas has a flow rate of from about 500 standard cubic centimeters per minute to about 20,000 standard cubic centimeters per minute; and treating the substrate by exposing the substrate to the first non-oxidizing plasma in the processing chamber.

  • Publication number: 20100065215
    Abstract: A plasma generating apparatus including a plurality of plasma source modules. Each plasma source module includes a ferrite core having high magnetic permeability and a plasma channel through which plasma may pass. The plasma generating apparatus may effectively generate and uniformly distribute large-area and high-density plasma without a dielectric window.

  • Patent number: 6667244
    Abstract: A method for removing organic and inorganic residues or polymers from the surface of semiconductor devices, with a combination of etchant gasses including water vapor generated using a catalytic moisture generator or CMG. The water vapor is generated by introducing O2 and an H2 containing forming gas including hydrogen and at least one dilutant gas into the CMG. The water vapor from the CMG is introduced into a reaction chamber with other etchant gasses to treat the surface of a semiconductor device placed within. The flow rate of water vapor out of the CMG and into the reaction chamber may be controlled by controlling the flow rate of the H2 containing forming gas and the flow rate of the O2 gas into the CMG.
