  • Double layer patterning and technique for milling patterns for a servo recording head
    Patent number: 7386934
    Abstract: Double photolithography is used to produce an under-layer of protective and filtering photoresist over a substrate that will have channels milled with a FIB. Secondary layers are applied with precision on top of the first layer in order to define the precise patterns to be milled and to provide targeting and alignment fiducials.
    Type: Grant
    Filed: January 26, 2006
    Date of Patent: June 17, 2008
    Assignee: Advanced Research Corporation
