    摘要: RC-trigger circuits for a semiconductor controlled rectifier (SCR), methods of providing electrostatic discharge (ESD) protection, and design structures for a RC-trigger circuit. The RC-trigger circuit is coupled to an input/output (I/O) signal pad by an isolation diode and is coupled to a power supply voltage by a power supply diode. Under normal operating conditions, the isolation diode is reverse biased, isolating the RC-trigger circuit from the input/output (I/O) pad, and the power supply diode is forward biased so that the RC-trigger circuit is supplied with power. The isolation diode may become forward biased during ESD events while the chip is unpowered, causing the RC-trigger circuit to trigger an SCR configured protect the signal pad from ESD into a conductive state. The power supply diode may become reverse biased during the ESD event, which isolates the power supply rail from the ESD voltage pulse.

    摘要: Design structures for high-voltage integrated circuits. The design structure, which is formed using a semiconductor-on-insulator (SOI) substrate, may include device structure with a semiconductor body positioned between first and second gate electrodes. The first and second gate electrodes and the semiconductor body may be formed from the monocrystalline SOI layer of the SOI substrate. A dielectric layer separates each of the first and second gate electrodes from the semiconductor body. These dielectric layers are formed by defining trenches in the SOI layer and filling the trenches with a dielectric material, which may occur concurrently with a process forming other device isolation regions.
