  • Testkey design pattern for gate oxide
    Patent number: 8084769
    Abstract: A testkey design pattern includes a least one conductive contact, at least one conductive line of a first width vertically and electrically connected to the conductive contact, and at least one pair of source and drain respectively directly connected to each side of the conductive line. The pair of source and drain and part of the conductive line of a first length directly connected to the source and drain form an electronic device. The testkey design patterns are advantageous in measuring capacitance with less error and for better gate oxide thickness extraction.
    Type: Grant
    Filed: February 16, 2007
    Date of Patent: December 27, 2011
    Assignee: United Microelectronics Corp.

  • Police-emergency system with wireless communication
    Patent number: 6954629
    Abstract: A police-emergency system of wireless communication which is to generate a signal by a control circuit of the magnetic card and transmits the signal onto the host server through the wireless communication module of said magnetic card, after the host server receives the signal coming from the magnetic card, it judges if the signal is in conformity with the data in the database by the microprocessor such that the signal will be transmitted onto the police-emergency system of police-citizen connection to notice the policemen arrive on the scene where crime happened.
