Field effect diode structures utilize a junction structure that has an L-shape in cross-section (a fin extending from a planar portion). An anode is positioned at the top surface of the fin, and a cathode is positioned at the end surface of the planar portion. The perpendicularity of the fin and the planar portion cause the anode and cathode to be perpendicular to one another. A first gate insulator contacts the fin between the top surface and the planar portion. A first gate conductor contacts the first gate insulator, and the first gate insulator is between the first gate conductor and the surface of the fin. Additionally, a second gate insulator contacts the planar portion between the end surface and the fin. A second gate conductor contacts the second gate insulator, and the second gate insulator is between the second gate conductor and the surface of the planar portion.

The present examples relate to a semiconductor chip having a level shifter with an electrostatic discharge (ESD) protection circuit and a device applying to multiple power supply lines with high and low power inputs to protect the level shifter from the static ESD stress. More particularly, the present examples relate to using a feature to protect a semiconductor device in a level shifter from the ESD stress by using ESD stress blocking region adjacent to a gate electrode of the semiconductor device. The ESD stress blocking region increases a gate resistance of the semiconductor device, which results in reducing the ESD stress applied to the semiconductor device itself.

Diffusion regions having the same conductivity type are arranged on a side of a second wiring and a side of a third wiring, respectively under a first wiring connected to a signal terminal. Diffusion regions are separated in a whole part or one part of a range in a Y direction. That is, under first wiring, diffusion regions are only formed in parts opposed to diffusion regions formed under the second wiring and third wiring connected to a power supply terminal or a ground terminal, and a diffusion region is not formed in a central part in an X direction. Therefore, terminal capacity of the signal terminal can be reduced without causing ESD resistance to be reduced, in an ESD protection circuit with the signal terminal.

The trigger source is electrically connected between the base of the BJT and the high voltage power line.
