  • Patent number: 9728630
    Abstract: A high-electron-mobility field effect transistor is formed with a buffer region having a stepped lateral profile, the stepped lateral profile having first, second and third cross-sections of the buffer region, the first cross-section being thicker than the third cross-section and including a buried field plate, the second cross-section interposed between the first and third cross-sections and forming oblique angles with the first and third cross-sections. A barrier region is formed along the stepped lateral profile. The barrier region is separated from the buried field plate by a portion of the buffer region. The buffer region is formed from a first semiconductor material and the barrier region is formed from a second semiconductor material. The first and second semiconductor materials have different band-gaps such that an electrically conductive channel of a two-dimensional charge carrier gas arises at an interface between the buffer and barrier regions.

  • Publication number: 20170200817
    Abstract: A method includes providing a heterostructure body with a buffer region, and a barrier region disposed on the buffer region, and forming a gate structure for controlling the channel on the heterostructure body, the gate structure having a doped semiconductor region disposed on the heterostructure body, an interlayer disposed on the doped semiconductor region, and a gate electrode disposed on the interlayer. Forming the gate structure includes controlling a doping concentration of the doped semiconductor region such that a portion of the channel adjacent the gate structure is non-conductive at zero gate bias, and controlling electrical and geometrical characteristics of the interlayer based upon a relationship between the electrical and geometrical characteristics of the interlayer and corresponding effects on a static threshold voltage and a dynamic threshold voltage shift of the semiconductor device.
