Abstract:
Diode structures and methods of fabricating diode structures. First and second gate structures are formed with the second gate structure arranged parallel to the first gate structure. First and second fins are formed that extend vertically from a top surface of a substrate. The first and second fins are arranged between the first gate structure and the second gate structure. A contact structure is coupled with the first fin and the second fin. The contact structure is laterally arranged between the first gate structure and the second gate structure.
Abstract:
Circuits for programming an electrical fuse, methods for programming an electrical fuse, and methods for designing a silicon-controlled rectifier for use in programming an electrical fuse. A programming current for the electrical fuse is directed through the electrical fuse and the silicon-controlled rectifier. Upon reaching a programmed resistance value for the electrical fuse, the silicon-controlled rectifier switches from a low-impedance state to a high-impedance state that interrupts the programming current.
Abstract:
Structures for laterally-diffused metal-oxide-semiconductor devices and drain-extended metal-oxide-semiconductor devices, as well as methods of forming laterally-diffused metal-oxide-semiconductor devices and drain-extended metal-oxide-semiconductor devices. A gate electrode is arranged to extend about a semiconductor fin projecting from a substrate. A drain region is arranged in the substrate, and a source region is coupled with the semiconductor fin. The source region is arranged over the semiconductor fin. A drift region is arranged in the substrate between the drain region and the semiconductor fin. The drain region, source region, and drift region have a given conductivity type. The drift region has a lower electrical conductivity than the drain region.

Abstract:
Silicon-controlled rectifiers and methods for forming a silicon-controlled rectifier. A first well of a first conductivity type is arranged in a substrate, and second and third wells of a second conductivity type are arranged in the substrate between the first well and the top surface of the substrate. A deep trench isolation region is laterally arranged between the first well of the second conductivity type and the second well of the second conductivity type. The second well is adjoined with the first well along a first interface, the third well is adjoined with the first well along a second interface, and the deep trench isolation region extends the top surface of the substrate past the first interface and the second interface and into the first well. A doped region of the first conductivity type is arranged in the substrate between the second well and the top surface of the substrate.
