    摘要: A normally-off transistor includes a first region of III-V semiconductor material, a second region of III-V semiconductor material on the first region, a third region of III-V semiconductor material on the second region and a gate electrode adjacent at least one sidewall of the third region. The first region provides a channel of the transistor. The second region has a band gap greater than the band gap of the first region and causes a 2-D electron gas (2DEG) in the channel. The second region is interposed between the first region and the third region. The third region provides a gate of the transistor and has a thickness sufficient to deplete the 2DEG in the channel so that the transistor has a positive threshold voltage.

    摘要: 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.

    摘要: A semiconductor device includes a semiconductor body including a plurality of compound semiconductor layers and a two-dimensional charge carrier gas channel region formed in one of the compound semiconductor layers. The semiconductor device further includes a contact structure disposed in the semiconductor body. The contact structure includes a metal region and a doped region. The metal region extends into the semiconductor body from a first side of the semiconductor body to at least the compound semiconductor layer which includes the channel region. The doped region is formed in the semiconductor body between the metal region and the channel region so that the channel region is electrically connected to the metal region through the doped region.
