    Abstract: A grounded gate NMOS transistor includes a P-type substrate, P-well region in the P-type substrate, and a gate finger traversing the P-well region. The gate finger has a first spacer on a first sidewall and a second spacer on a second sidewall opposite to the first sidewall. An N+ drain doping region is disposed in the P-type substrate and is adjacent to the first sidewall of the gate finger. The N+ drain doping region is contiguous with a bottom edge of the first spacer. An N+ source doping region is disposed in the P-type substrate opposite to the N+ drain doping region. The N+ source doping region is kept a predetermined distance from a bottom edge of the second spacer. A P+ pick-up ring is disposed in the P-well region and surrounds the gate finger, the N+ drain doping region, and the N+ source doping region.

    Abstract: An ESD protection semiconductor device is disclosed. The ESD protection semiconductor device includes a substrate and a gate set disposed on the substrate. A plurality of source fins and a plurality of drain fins are formed in the substrate respectively at two sides of the gate set. At least a first doped fin is formed in the substrate at one side of the gate set the same as the source fins. A plurality of isolation structures are formed in one of the drain fins to define at least a second doped fin in the one of the drain fins. The source fins and the drain fins are of a first conductivity type. The first doped fin is of a second conductivity type that is complementary to the first conductivity type. The first doped fin and the second doped fin are electrically connected to each other.

    Abstract: A semiconductor device is described, including a substrate including a first area and a second area, a first MOS element of a first conductivity type in the first area, and a second MOS element of the first conductivity type in the second area. The first area is closer to a pick-up region of the substrate than the second area. The substrate has a second conductivity type. The bottom depth of a first electrical conduction path in the substrate in the first area is smaller than that of a second electrical conduction path in the substrate in the second area.
