    • A combined bipolar-field effect transistor RESURF device includes a lightly-doped epitaxial buried layer of a first conductivity type located between a semiconductor substrate of the first conductivity type and an epitaxial surface layer of a second conductivity type opposite to that of the first. The doping concentration and thickness of the epitaxial surface layer are selected in accordance with the Reduced Surface Field (RESURF) technique. A highly-doped buried region of the second conductivity type is located beneath the base region of the device and is sandwiched between the epitaxial buried layer and the epitaxial surface layer. The advantages of such a device include a substantially reduced "on" resistance, a more compact and flexible configuration, improved switching characteristics, reduced base device current requirements, and improved isolation. The device may be further enhanced by providing a buried annular region of the first conductivity type around and in contact with the buried region, and a surface-adjoining annular region of the first conductivity may be provided adjacent the base region.
    • 组合双极场效应晶体管RESURF器件包括位于第一导电类型的半导体衬底与第一导电类型的第二导电类型的外延表面层与第一导电类型相反的第一导电类型的轻掺杂外延掩埋层。 根据减少表面场(RESURF)技术选择外延表面层的掺杂浓度和厚度。 第二导电类型的高掺杂掩埋区域位于器件的基极区域的下方并夹在外延掩埋层和外延表面层之间。 这种器件的优点包括显着降低的“导通”电阻,更紧凑和灵活的配置,改进的开关特性,降低的基极器件电流要求以及改进的隔离。 可以通过在掩埋区域周围提供第一导电类型的掩埋环形区域并且与掩埋区域接触来进一步增强该器件,并且可以在基极区域附近提供与第一导电性的表面相邻的环形区域。
