ABSTRACT:
An electrostatic discharge device may provide better protection of an integrated circuit by more uniform breakdown of a plurality of finger regions. The plurality of finger regions may extend through a first region of a substrate having a first conductivity type and into a second region of the substrate more lightly doped with impurities of the first conductivity type. An electrostatic discharge device may include a collector region having a middle region that may be highly doped with impurities of the first conductivity type. The middle region may be proximate to a layer that is lightly doped with impurities of the first conductivity type and a layer that is doped with impurities of the second conductivity type. The collector region may decrease the breakdown voltage of the electrostatic discharge device.
