    摘要: A Schottky barrier diode includes a semiconductor substrate, an ohmic electrode formed on a first region of the semiconductor substrate, and a Schottky metal electrode formed on a second region spaced apart from the first region on the semiconductor substrate. The Schottky electrode includes at least one ohmic portion forming an ohmic contact with the semiconductor substrate, whereby rectifying characteristics of the Schottky barrier diode are improved.

    摘要: A heterostructure insulated-gate field effect transistor comprises a channel layer, barrier layer and a contact layer. The barrier layer is made of a material having an electron affinity smaller than that of the channel layer and equal to that of the contact layer. Due to the single heterostructure, the series resistance between the channel layer and the source (drain) electrode can be decreased without employing complicated selective ion implanting or selective epitaxial growing method.
