  • Patent number: 11152313
    Abstract: The independent claims of this patent signify a concise description of embodiments. Roughly described, a physically unclonable function (PUF) device includes a crystalline substrate and a stack of crystalline layers on top. The stack is grown epitaxially such that lattice mismatch causes threading dislocations from the substrate to the top surface of the stack. Diodes are formed on the top surface by forming anode material on the top surface of the stack, thereby forming a diode junction with a cathode region below. A diode which includes a threading dislocation has a higher leakage current than one that does not. Circuitry connected to the diodes interrogates the array and outputs binary values indicating, for each of the diodes, whether the diode includes a threading dislocation. Such binary values can be used as the PUF of the chip. This Abstract is not intended to limit the scope of the claims.

  • Patent number: 10777638
    Abstract: Roughly described, an integrated circuit device includes a semiconductor having an overall length. In successively adjacent longitudinal sequence, the semiconductor includes first, second and third lengths all having a same first conductivity type. One end of the longitudinal sequence (the end adjacent to the first length) can be referred to a source end of the sequence, and the other end (adjacent to the third length) can be referred to as a drain end. Overlying the second length is a first gate conductor, which defines a first body region. Overlying a cascode portion of the third length is a second gate conductor, which defines a second body region. The second gate conductor preferably is longitudinally continuous with the first gate conductor, but if not, then the two are connected together by other conductors. The first body region is recessed relative to the first and third lengths of the semiconductor.
