  • Patent number: 10665711
    Abstract: A high-electron-mobility transistor (HEMT) includes a substrate layer of silicon, a first contact disposed on a first surface of the substrate layer, and a number of layers disposed on a second surface of the substrate layer opposite the first surface. A second contact and a gate contact are disposed on those layers. A trench containing conducting material extends completely through the layers and into the substrate layer. In an embodiment of the HEMT, the first contact is a drain contact and the second contact is a source contact. In another embodiment of the HEMT, the first contact is a source contact and the second contact is a drain contact.
    Type: Grant

  • Patent number: 7701012
    Abstract: An electrostatic discharge (ESD) protection clamp (61) for I/O terminals (22, 23) of integrated circuits (ICs) (24) comprises an NPN bipolar transistor (25) coupled to an integrated Zener diode (30). Variations in the break-down current-voltage characteristics (311, 312, 313, 314) of multiple prior art ESD clamps (31) in different parts of the same IC chip is avoided by forming the anode (301) of the Zener (30) in the shape of a base-coupled P+ annular ring (75) surrounded by a spaced-apart N+ annular collector ring (70) for the cathode (302) of the Zener (30).
