  • Single semiconductor wafer transfer method and manufacturing system
    Patent number: 5976199
    Abstract: A manufacturing system for individually processing semiconductor wafers through a plurality of processing stations. The system has a plurality of processing stations, a multilevel track system that interfaces with the processing stations, and guided transport vehicles that operate on the track system to move individual wafers in wafer carriers between the stations. The carriers have a storage memory that contains the required process sequence and the capability to remember the completed process steps.
    Type: Grant
    Filed: February 14, 1997
    Date of Patent: November 2, 1999
    Assignee: United Microelectronics Corp.
    Inventors: Hong-Jen Wu, Taylor Chen, Jack Lai, I. I. Chen
