    Abstract: An electrostatic discharge (ESD) circuit includes an ESD detection circuit, a clamp circuit and an ESD assist circuit. The ESD detection circuit is coupled between a first and a second node. The first node has a first voltage. The second node has a second voltage. The clamp circuit includes a first transistor having a first gate, a first drain, a first source and a first body terminal. The first gate is coupled to at least the ESD detection circuit by a third node. The first drain is coupled to the second node. The first source and the first body terminal are coupled together at the first node. The ESD assist circuit is coupled between the first node and the third node, and is configured to clamp a third voltage of the third node at the first voltage during an ESD event at the first node or the second node.

    Abstract: A semiconductor device includes a first doped zone and a second doped zone in a first semiconductor material, the first doped zone being separated from the second doped zone; an isolation structure between the first doped zone and the second doped zone; and a first line segment over a top surface of the first doped zone, where the ends of the first line segment and the ends of the second line are over the isolation structure. The first line segment and the second line segment have a first width; and a dielectric material is between the first line segment and the second line segment and over the isolation structure. The first width is substantially similar to a width of a gate electrode in the semiconductor device.

    Abstract: A method of making a semiconductor device includes manufacturing doped zones in a first semiconductor material over a substrate. The method further includes forming an isolation structure between adjacent doped zones of the first semiconductor material. The method further includes manufacturing lines extending in a first direction over the doped zones of the first semiconductor material, wherein each of the lines has a line width measured along a second direction perpendicular to the first direction. The method further includes trimming the lines into line segments having ends over the isolation structure. The method further includes etching a transistor gate electrode over the substrate, wherein transistor gate electrode has a gate electrode width measured along the second direction, and wherein the line width is substantially similar to the gate electrode width.
