  • Patent number: 11152352
    Abstract: A dual mode snap back circuit device is disclosed. The dual mode snap back device may be used for electrostatic discharge (ESD) protection, and may provide both positive ESD protection and negative ESD protection. The dual mode snap back device may implement both an n-type metal-oxide-semiconductor (NMOS) transistor (e.g., a gate-grounded NMOS transistor, such as a gate-grounded extended drain NMOS (GGEDNMOS) transistor) to provide protection against positive ESD events and a bipolar junction transistor (BJT) (e.g., a PNP BJT) to provide protection against negative ESD events. Other embodiments may be described and claimed.
    Type: Grant

  • Patent number: 10103542
    Abstract: Snapback ESD protection device employing one or more non-planar metal-oxide-semiconductor transistors (MOSFETs) are described. The ESD protection devices may further include lightly-doped extended drain regions, the resistances of which may be capacitively controlled through control gates independent of a gate electrode held at a ground potential. Control gates may be floated or biased to modulate ESD protection device performance. In embodiments, a plurality of core circuits are protected with a plurality of non-planar MOSFET-based ESD protection devices with control gate potentials varying across the plurality.
