  • Fabricating sub-lithographic contacts
    Patent number: 8067260
    Abstract: A small critical dimension element, such as a heater for an ovonic unified memory, may be formed within a pore by using successive sidewall spacers. The use of at least two successive spacers enables the limitations imposed by lithography and the limitations imposed by bread loafing be overcome to provide reduced critical dimension elements.
    Type: Grant
    Filed: June 3, 2010
    Date of Patent: November 29, 2011
    Assignee: Micron Technology, Inc.

  • Bond pad redistribution layer for thru semiconductor vias and probe touchdown
    Publication number: 20060060845
    Abstract: A semiconductor device having a conductive layer above a dielectric layer and a top metal layer. The conductive layer is patterned to form an alternate probe area to test the functionality of active circuitry within the semiconductor device and patterned to electrically route a thru semiconductor via within the semiconductor device to an alternate junction point.
