Patent number: 6721289Abstract: A radio frequency identification device comprises an integrated circuit including a receiver, a transmitter, and a microprocessor. The receiver and transmitter together define an active transponder. The integrated circuit is preferably a monolithic single die integrated circuit including the receiver, the transmitter, and the microprocessor. Because the device includes an active transponder, instead of a transponder which relies on magnetic coupling for power, the device has a much greater range.Type: GrantFiled: February 11, 2000Date of Patent: April 13, 2004Assignee: Micron Technology, Inc.Inventors: James E. O'Toole, John R. Tuttle, Mark E. Tuttle, Tyler Lowrey, Kevin M. Devereaux, George E. Pax, Brian P. Higgins, David K. Ovard, Shu-Sun Yu, Robert R. Rotzoll

Publication number: 20030042600Abstract: The present invention provides a method and apparatus which facilitates wafer level burn-in testing of semiconductor dies. Sacrificial busses on the wafer supply voltage to respective on die Vcc and Vss sacrificial voltage pads during burn-in testing. The Vcc sacrificial pad on each die is connected to a secondary Vcc pad through an on-die sacrificial metal bus. An on-die fuse is interposed between the secondary Vcc pad and a normal Vcc die bonding pad. The fuse will blow when a die draws excessive current isolating a defective die from other dies on the wafer which are connected to the sacrificial busses. The Vss sacrificial pad is connected to a normal Vss die bonding pad through a sacrificial metal bus. After burn-in testing, the structures are removed. During this removal, the on-die sacrificial metal busses protect the secondary Vcc pad and Vss bonding pad. The secondary Vcc pad, Vcc bonding pad and Vss bonding pad can then be exposed for additional die testing.Type: ApplicationFiled: June 21, 2002Publication date: March 6, 2003Inventor: Kevin M.
