摘要:
An ultra-high voltage n-type-metal-oxide-semiconductor (UHV NMOS) device with improved performance and methods of manufacturing the same are provided. The UHV NMOS includes a substrate of P-type material; a first high-voltage N-well (HVNW) region disposed in a portion of the substrate; a source and bulk p-well (PW) adjacent to one side of the first HVNW region, and the source and bulk PW comprising a source and a bulk; a gate extended from the source and bulk PW to a portion of the first HVNW region, and a drain disposed within another portion of the first HVNW region that is opposite to the gate; a P-Top layer disposed within the first HVNW region, the P-Top layer positioned between the drain and the source and bulk PW; and an n-type implant layer formed on the P-Top layer.

A semiconductor structure and a manufacturing method for the same are provided. The semiconductor structure includes a first doped well, a first doped electrode, a second doped electrode, doped strips and a doped top region. The doped strips are on the first doped well between the first doped electrode and the second doped electrode. The doped strips are separated from each other. The doped top region is on the doped strips and extended on the first doped well between the doped strips. The first doped well and the doped top region have a first conductivity type. The doped strips have a second conductivity type opposite to the first conductivity type.

A high-voltage metal-oxide-semiconductor (HVMOS) device may include a source, a drain, a gate positioned proximate to the source, a drift region disposed substantially between the drain and a region of the gate and the source, and a self shielding region disposed proximate to the drain. A corresponding method is also provided.

A semiconductor structure and method for manufacturing the same are provided. The semiconductor structure includes a substrate having a first conductive type; a deep well having a second conductive type formed in the substrate and extending down from a surface of the substrate; a first well having the first conductive type formed in the deep well and extending down from the surface of the substrate; and a second well having the second conductive type formed in the deep well and extending down from the surface of the substrate, and the second well adjacent to the first well. The first well includes a block region and plural finger regions joined to one side of the block region, while the second well includes plural channel regions interlaced with the finger regions to separate the finger regions.
