  • Influence of elastic strains on the mask ratio in glassy polymer nanoimprint 

    CROSS, GRAHAM; O'CONNELL, BARRY SEAMUS; PETHICA, JOHN BERNARD (American Institute of Physics, 2005)
    During glassy polymer nanoimprint, a supported film is extruded from protruding spunchd to recessed scavityd regions of a patterned stamp. The completeness of this extrusion determines the mask ratio for lithographic ...

  • Mechanical aspects of nanoimprint patterning 

    CROSS, GRAHAM; O'CONNELL, BARRY SEAMUS; PETHICA, JOHN BERNARD (IEEE, 2003)
    Nanoimprinting is a high resolution, parallel nanopatterning technique where, typically, a rigid stamp is brought into contact with a thin polymer film and pattern transfer achieved by the application of force and heat. ...

  • Nanorheology of squeezed polymer films 

    CROSS, GRAHAM; O'CONNELL, BARRY SEAMUS; PETHICA, JOHN BERNARD (IEEE, 2003)
    We present investigations of submicrometer quasi-two dimensional flow mechanics of squeezed thin polymer films in the context of nanoimprint lithography. The polymer films were indented by patterned spherical indenters ...
