Abstract:
The present disclosure relates to four-layer latching devices having improved reverse current capabilities. The devices have a localized doping spike region in the upper base region, the lower base region, or both. The localized doping spike regions have a localized doping concentration that is greater than the doping concentration of the layer where the localized doping spike region is located. Within the base regions the localized spikes are located next to the corresponding upper emitter region, lower emitter region, or both.

Claim (Index 22):
A semiconductor latching device, comprising:\n an upper emitter junction formed at an interface between an upper emitter region having a first doping concentration and an upper base region having a second doping concentration; and a lower emitter junction formed at an interface between a lower base region having a third doping concentration and the lower emitter region having a fourth doping concentration; wherein the upper base region comprises an upper localized doping spike region at the upper emitter junction, wherein the upper localized doping spike region has an upper localized doping concentration greater than the second doping concentration, and wherein the lower base region does not include a lower localized doping spike region at the upper emitter junction, wherein the lower base region comprises a buffer region having a fifth doping concentration at the lower emitter junction.
