    摘要: Planar and non-planar field effect transistors with extended-drain structures, and techniques to fabricate such structures. In an embodiment, a field plate electrode is disposed over an extended-drain, with a field plate dielectric there between. The field plate is disposed farther from the transistor drain than the transistor gate. In a further embodiment, an extended-drain transistor has source and drain contact metal at approximately twice a pitch, of the field plate and the source and/or drain contact metal. In a further embodiment, an isolation dielectric distinct from the gate dielectric is disposed between the extended-drain and the field plate. In a further embodiment, the field plate may be directly coupled to one or more of the transistor gate electrode or a dummy gate electrode without requiring upper level interconnection. In an embodiment, a deep well implant may be disposed between a lightly-doped extended-drain and a substrate to reduce drain-body junction capacitance and improve transistor performance.

    摘要: An N type lateral double diffused metal oxide semiconductor (NLDMOS) device comprises a floating P type structure (115), a first field oxide region (107), a second field oxide region (109) and an N type drift region (113), wherein the first field oxide region (107) and the second field oxide region (109) are disposed on the N type drift region (113); the floating P type structure (115) is located in the middle portion of the N type drift region (113); the first field oxide region (107) and the second field oxide region (109) are not connected together; and width of active region between the first field oxide region (107) and the second field oxide region (109) matches with length of the injected floating P type structure (115). By employing the construction of the NLDMOS, not only the breakdown voltage of semiconductor device can be raised, but also on-resistance can be effectively lowered. Meanwhile, the requirements of high-energy injection are lowered and the limitation to processing machine is decreased, making the manufacturing easier to be carried out.
