Pradeep R. Yelehanka 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).

  • Thyristor-based SRAM
    Patent number: 7285804
    Abstract: An integrated circuit structure includes a semiconductor substrate and a horizontal semiconductor fin on top of the semiconductor substrate. An access transistor gate and a thyristor gate are on top of the semiconductor substrate and in contact with the horizontal semiconductor fin. An access transistor is at least a portion of the horizontal semiconductor fin and the access transistor gate. A thyristor is at least a portion of the horizontal semiconductor fin and the thyristor gate, the access transistor is in contact with the thyristor.
    Type: Grant
    Filed: March 10, 2005
    Date of Patent: October 23, 2007
    Assignee: Chartered Semiconductor Manufacturing Ltd.
    Inventors: Elgin Quek, Jia Zhen Zheng, Pradeep R. Yelehanka, Weining Li
  • Method using quasi-planar double gated fin field effect transistor process for the fabrication of a thyristor-based static read/write random-access memory
    Patent number: 6897111
    Abstract: A method for manufacturing an integrated circuit structure includes providing a semiconductor substrate and forming a horizontal semiconductor fin on top of the semiconductor substrate. An access transistor gate and a thyristor gate are then formed on top of the semiconductor substrate and in contact with the horizontal semiconductor fin. An access transistor is formed from at least a portion of the horizontal semiconductor fin and the access transistor gate. A thyristor is formed from at least a portion of the horizontal semiconductor fin and the thyristor gate, the access transistor being in contact with the thyristor.
