    Abstract: A semiconductor device for electrostatic discharge (ESD) protection includes a doped well, a drain region, a source region, a first doped region and a guard ring. The doped well is disposed in a substrate and has a first conductive type. The drain region is disposed in the doped well and has a second conductive type. The source region is disposed in the doped well and has the second conductive type, wherein the source region is separated from the drain region. The doped region is disposed in the doped well between the drain region and the source region, wherein the doped region has the first conductive type and is in contact with the doped well and the source region. The guard ring is disposed in the doped well and has the first conductive type.

    Abstract: A semiconductor structure comprises a well, a first lightly doped region, a second lightly doped region, a first heavily doped region, a second heavily doped region and a gate. The first lightly doped region is disposed in the well. The second lightly doped region is disposed in the well and separated from the first lightly doped region. The first heavily doped region is disposed in the first lightly doped region. The second heavily doped region is partially disposed in the second lightly doped region. The second heavily doped region has a surface contacting the well. The gate is disposed on the well between the first heavily doped region and the second heavily doped region. The well has a first doping type. The first lightly doped region, the second lightly doped region, the first heavily doped region and the second heavily doped region have a second doping type.

    Abstract: A fin type ESD protection device includes at least one first fin, at least one second fin, and at least one gate structure. The first fin is disposed on a semiconductor substrate, and a source contact contacts the first fin. The second fin is disposed on the semiconductor substrate, and a drain contact contacts the second fin. The first fin and the second fin extend in a first direction respectively, and the first fin is separated from the second fin. The gate structure is disposed between the source contact and the drain contact. The first fin is separated from the drain contact, and the second fin is separated from the source contact.
