Logic devices are provided in multiple sub-collector and sub-emitter microplasma devices formed in thin and flexible, or inflexible, semiconductor materials. Logic operations are provided with one of a plurality of microplasmas forming sub-collectors with a common emitter, or a common collector plasma with a plurality of sub-emitter regions in a solid state semi-conductor pn-junction, and generating a logic output from an electrode, based upon electrode inputs to two other electrodes.
