  • Patent number: 10170459
    Abstract: Methods to forming low trigger-voltage ESD protection circuit in FinFET IC devices and resulting devices. Embodiments include providing a substrate including a first-type well area in an ESD region; forming a base junction of the first-type along the perimeter of the ESD region; forming a shallow trench isolation (STI) region adjacent the base junction; forming alternate emitter and collector junctions of a second-type adjacent the STI region, parallel to and spaced from each other by parallel additional STI regions; forming at least one gate perpendicular to and over a collector junction; and forming a floating ESD nodes of the first-type in the collector junction adjacent one side of the at least one gate.

  • Patent number: 10032761
    Abstract: Electronic devices and methods of producing such electronic devices are provided. In an exemplary embodiment, a method of producing an electronic device includes forming a protected circuit and an ESD circuit, where the ESD circuit is configured to discharge an electrostatic discharge (ESD) to a ground such that the ESD bypasses the protected circuit. An ESD transistor is formed in the ESD circuit, where the ESD transistor includes a source and a drain. The ESD transistor also includes a gate with a gate width perpendicular to a gate length, where the gate length is measured across the gate from the source to the drain. A trigger voltage of the ESD transistor is set by adjusting the gate width.

  • Publication number: 20180082995
    Abstract: Integrated circuits and methods of producing the same are provided. In an exemplary embodiment, an integrated circuit includes a substrate and a source in electrical communication with the substrate. A drain is also in electrical communication with the substrate. A gate overlies the substrate between the source and the drain, wherein a channel is defined within the substrate directly underlying the gate, and where a Schottky portion of the substrate is positioned between the channel and the source.
