  • Method for improving semiconductor surfaces
    Patent number: 7776624
    Abstract: A semiconductor fabrication method. The method includes providing a semiconductor substrate, wherein the semiconductor substrate includes a semiconductor material. Next, a top portion of the semiconductor substrate is removed. Next, a first semiconductor layer is epitaxially grown on the semiconductor substrate, wherein a first atomic percent of a first semiconductor material in the first semiconductor layer is equal to a substrate atomic percent of the substrate semiconductor material in the semiconductor substrate.
    Type: Grant
    Filed: July 8, 2008
    Date of Patent: August 17, 2010
    Assignee: International Business Machines Corporation
    Inventors: Ashima B. Chakravarti, Judson Robert Holt, Jeremy John Kempisty, Suk Hoon Ku, Woo-Hyeong Lee, Amlan Majumdar, Ryan Matthew Mitchell, Renee Tong Mo, Zhibin Ren, Dinkar Singh
