  • III-V semiconductor devices with buried contacts
    Patent number: 8569799
    Abstract: A semiconductor device such as a diode or transistor includes a semiconductor substrate, a first region of III-V semiconductor material on the semiconductor substrate and a second region of III-V semiconductor material on the first region. The second region is spaced apart from the semiconductor substrate by the first region. The second region is of a different composition than the first region. The semiconductor device further includes a buried contact extending from the semiconductor substrate to the second region through the first region. The buried contact electrically connects the second region to the semiconductor substrate.
