    Abstract: An electrostatic discharge (ESD) protection device includes a semiconductor substrate, a gate structure, a source doped region, a drain doped region, source silicide patterns, and drain silicide patterns. The gate structure is disposed on the semiconductor substrate. The source doped region and the drain doped region are disposed in the semiconductor substrate and located at two opposite sides of the gate structure in a first direction, respectively. The source silicide patterns are disposed on the source doped region. The source silicide patterns are arranged in a second direction and separated from one another. The drain silicide patterns are disposed on the drain doped region. The drain silicide patterns are arranged in the second direction and separated from one another. The source silicide patterns and the drain silicide patterns are arranged misaligned with one another in the first direction.

    Abstract: An ESD protection device on a substrate includes a base doped region of a first conductivity type. A first inter doped region of a second conductivity type is in the base doped region. A drain region of the second conductivity type in the first inter doped region is connected to a first electrode terminal. An inserted doped region of the first conductivity type is in the drain region. A second inter doped region of the second conductivity type is in the base doped region. A source region of the second conductivity type is in the second inter doped region. A substrate-surface doped region of the first conductivity type in the substrate is adjacent to or in contact with the source region. A gate structure is between the drain and source regions in the substrate. The substrate-surface doped region and the source region are connected to a second electrode terminal.

    Abstract: A method for fabricating a semiconductor device is provided. A fin of a first conductivity type is formed on a substrate of the first conductivity type. A gate is formed on the substrate, wherein the gate covers a portion of the fin. Source and drain regions of a second conductivity type are formed in the fin at respective sides of the gate. A punch-through stopper (PTS) of the first conductivity type is formed in the fin underlying the gate and between the source and drain regions, wherein the PTS has an impurity concentration higher than that of the substrate. A first impurity of the second conductivity type is implanted into the PTS, so as to compensate the impurity concentration of the PTS.
