Abstract: Disclosed are semiconductor structures. Each semiconductor structure can comprise a substrate and at least one laterally double-diffused metal oxide semiconductor field effect transistor (LDMOSFET) on the substrate. Each LDMOSFET can have a fully-depleted deep drain drift region (i.e., a fully depleted deep ballast resistor region) for providing a relatively high blocking voltage. Different configurations for the drain drift regions are disclosed and these different configurations can also vary as a function of the conductivity type of the LDMOSFET. Additionally, each semiconductor structure can comprise an isolation band positioned below the LDMOSFET and an isolation well positioned laterally around the LDMOSFET and extending vertically to the isolation band such that the LDMOSFET is electrically isolated from both a lower portion of the substrate and any adjacent devices on the substrate.

Abstract: Circuits and methods of fabricating circuits that provide electrostatic discharge protection, as well as methods of protecting an integrated circuit from an electrostatic discharge event at an input/output pin. The protection circuit includes a silicon-controlled rectifier having a well and an anode in the well. The anode is coupled with the input/output pin. The protection circuit further includes a control circuit coupled with the well. The control circuit is configured to supply a first control logic voltage to the well that places the silicon-controlled rectifier in a blocking state, and a second control logic voltage to the well that places the silicon-controlled rectifier in a low impedance state. When placed in its low impedance state, the silicon-controlled rectifier is configured to divert current from the electrostatic discharge event at the input/output pin away from the integrated circuit.
