  • Semiconductor wafer transfer arm
    Patent number: 11551964
    Abstract: A semiconductor wafer transfer arm includes, in one embodiment, a mechanical arm and a contact pad including contact points. The contact points are configured to secure a semiconductor wafer at a non-active area of the semiconductor wafer and offset the contact pad from an active area of the semiconductor wafer by a predetermined distance. The transfer arm prevents foreign material from contacting the wafer and thus reduces instances of die cracking caused by foreign material during a semiconductor wafer transfer process.
    Type: Grant
    Filed: June 29, 2021
    Date of Patent: January 10, 2023
    Assignee: Western Digital Technologies, Inc.
