  • Patent number: 4745445
    Abstract: A high frequency, e.g. millimeter wave, semiconductor diode structure includes a buried layer of n.sup.+ -type material and a surface layer of lightly doped n-type material on which a Schottky barrier contact is disposed. The n.sup.+ -type layer provides a low series resistance thus permitting high frequency operation. The structure is compatible with MESFET processing techniques and may thus be incorporated in an integrated circuit.
