Patents by Inventor John Lee Klocke

John Lee Klocke has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10354875
    Abstract: A method may include forming a sacrificial mask on a device structure, the sacrificial mask comprising a carbon-based material. The method may further include etching memory structures in exposed regions of the sacrificial mask, implanting an etch-enhancing species into the sacrificial mask, and performing a wet etch to selectively remove the sacrificial mask at etch temperature, less than 350° C.
    Type: Grant
    Filed: April 6, 2018
    Date of Patent: July 16, 2019
    Assignee: Varian Semiconductor Equipment Associates, Inc.
    Inventors: Rajesh Prasad, Ning Zhan, Tzu-Yu Liu, James Cournoyer, Kyu-Ha Shim, Kwangduk Lee, John Lee Klocke, Eric J. Bergman, Terrance Lee, Harry S. Whitesell

  • Patent number: 9234293
    Abstract: Processes and systems for electrolytically processing a microfeature workpiece with a first processing fluid and a counter electrode are described. Microfeature workpieces are electrolytically processed using a first processing fluid, a counter electrode, a second processing fluid, and an anion permeable barrier layer. The anion permeable barrier layer separates the first processing fluid from the second processing fluid while allowing certain anionic species to transfer between the two fluids.

  • Patent number: 8852417
    Abstract: Processes and systems for electrolytically processing a microfeature workpiece with a first processing fluid and a counter electrode are described. Microfeature workpieces are electrolytically processed using a first processing fluid, a counter electrode, a second processing fluid, and an anion permeable barrier layer. The anion permeable barrier layer separates the first processing fluid from the second processing fluid while allowing certain anionic species to transfer between the two fluids. Some of the described processes produce deposits over repeated plating cycles that exhibit resistivity values within desired ranges.
