Publication number: 20140048108Abstract: A method and system for cleaning a surface of a substrate after an etching operation includes determining a plurality of process parameters associated with the surface of the substrate. The process parameters define characteristics related to the surface of the substrate such as characteristics of the substrate surface to be cleaned, contaminants to be removed, features formed on the substrate and chemicals used in the fabrication operations. A plurality of application chemistries are identified based on the process parameters. The plurality of application chemistries includes a first application chemistry as an emulsion having a first immiscible liquid combined with a second immiscible liquid and solid particles distributed within the first immiscible liquid.Type: ApplicationFiled: March 13, 2008Publication date: February 20, 2014Applicant: LAM RESEARCH CORPORATIONInventors: Seokmin Yun, Ji Zhu, John M. deLarios, Mark Wilcoxson

Patent number: 8652268Abstract: A method for treating substrates with treating liquids, using a treating tank for storing the treating liquids, a holding mechanism for holding the substrates in a treating position inside the treating tank, first and second treating liquid supply devices, a temperature control device, and a control device. A first treating liquid is supplied into the treating tank, then a second treating liquid of lower surface tension and higher boiling point than the first treating liquid is supplied, and placed in a temperature range above the boiling point of the first treating liquid and below the boiling point of the second treating liquid. Then the second treating liquid supply device may be controlled to replace the first treating liquid with the second treating liquid, while controlling the temperature control device to maintain the second treating liquid in the same temperature range.Type: GrantFiled: January 28, 2011Date of Patent: February 18, 2014Assignee: Dainippon Screen Mfg. Co., Ltd.Inventor: Toyohide Hayashi

Patent number: 8652266Abstract: A system and method for removing polymer residue from around a metal gate structure formed on a surface of a substrate during a post-etch cleaning operation includes determining a plurality of process parameters associated with the metal gate structure and the polymer residue to be removed. A plurality of fabrication layers define the metal gate structure and the process parameters define characteristics of the fabrication layers and the polymer residue. A first cleaning chemistry and second cleaning chemistry are identified and a plurality of application parameters associated with the first and second cleaning chemistries are defined based on the process parameters. The first and second application chemistries are applied sequentially in a controlled manner using the application parameters to substantial remove the polymer residue while preserving the structural integrity of the gate structure.Type: GrantFiled: September 17, 2008Date of Patent: February 18, 2014Assignee: Lam Research CorporationInventors: Katrina Mikhaylichenko, Yizhak Sabba, Dragan Podlesnik

Patent number: 8652267Abstract: There is disclosed a coated-type silicon-containing film stripping process for stripping off to remove a coated-type silicon-containing film obtained by coating a silicon-containing film composition used in a lithography on a substrate, comprising, at least: a first step of treating the silicon-containing film with an acidic stripping solution containing sulphate ion and/or fluoride ion; and a second step of treating the silicon-containing film with an alkaline stripping solution containing a nitrogen compound. There can be provided a process for allowing a silicon-containing film, which has not been conventionally removed unless dry stripping is adopted, to be removed by a stripping process based on a stripping solution (wet stripping).Type: GrantFiled: November 9, 2009Date of Patent: February 18, 2014Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Tsutomu Ogihara, Takafumi Ueda, Toshiharu Yano, Shozo Shirai
