    摘要: A semiconductor device with having a MOS varactor and methods of fabricating the same are disclosed. The MOS varactor includes a metal gate electrode, an active semiconductor plate interposed between the metal gate electrode and the semiconductor substrate, and a capacitor dielectric layer interposed between the metal gate electrode and the active semiconductor plate. Further, a lower insulating layer insulates the MOS varactor from the semiconductor substrate. According to the present invention, a metal gate electrode is used to reduce poly depletion, thereby increasing a tuning range of the varactor, and to manufacture a reliable metal resistor without the need of an additional photomask.

    摘要: A high power semiconductor device and its fabrication method in which source and the drain regions are spaced apart from and edge of a field oxide layer. This allows the junction profile to become gently-sloped so that the junction breakdown voltage is increased. Also, since the edge of the field oxide layer is covered by the field plate and a ground voltage or below the ground voltage is applied to the field plate, the distribution of the strong electric field formed at the edge of the field oxide layer is dispersed, to further increase the junction breakdown voltage. Moreover, since the field plate covers the field oxide layer at the side of the drain of the high power semiconductor device, when a high voltage is applied to the drain, the electric field distribution is dispersed, so that the junction breakdown voltage at the edge of the gate electrode at the side of the drain can be increased.
