  • Method of patterning a metal layer
    Patent number: 6165911
    Abstract: A metal layer is patterned by compression moulding using a stamp to create a thickness contrast pattern, followed by etching to transfer the thickness contrast pattern into the entire thickness of the metal layer. The stamp is typically patterned using a technique such as electron beam lithography, and the etchant typically etches through the entire metal layer. The method is used to produce structures such as microelectronic circuits.
