Abstract: Electrostatic discharge (ESD) devices for protection of integrated circuits are described. ESD devices may be configured to provide uniform breakdown of finger regions extending 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. Such an EDS device may include a collector region having a middle region 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 EDS device. The lightly doped region may be eliminated in the collector region and an interlayer insulating layer is formed in contact with the top side regions and the middle region.
