    摘要: In this invention a deep N-type wall is created surrounding an area that contains an ESD device, or circuit. The ESD device, or circuit, is connected to a chip pad and is first surrounded by a P+ guard ring. The P+ guard ring is then surrounded by the deep N-type wall to block excess current from an ESD event or voltage overshoot from reaching the internal circuitry. The deep N-type wall comprises an N+ diffusion within an N-well which is on top of a deep N-well. The height of the deep N-type wall is approximately 4 to 6 micrometers which provides a capability to absorb much of the current from an ESD event or voltage overshoot.

    摘要: An electrostatic discharge protection device comprising a multi-finger gate, a first lightly doped region of a second conductivity, a first heavily doped region of the second conductivity, and a second lightly doped region of the second conductivity. The multi-finger gate comprises a plurality of fingers mutually connected in parallel over an active region of a first conductivity. The first lightly doped region of a second conductivity is disposed in the semiconductor substrate and between two of the fingers. The first heavily doped region of the second conductivity is disposed in the first lightly doped region of the second conductivity. The second lightly doped region of the second conductivity is beneath and adjoins the first lightly doped region of the second conductivity.
