Abstract:
A nonvolatile programmable switch device using a phase-change memory device and a method of manufacturing the same are provided. The switch device includes a substrate, a first metal electrode layer disposed on the substrate and including a plurality of terminals, a phase-change material layer disposed on the substrate and having a self-heating channel structure, the phase-change material layer having a plurality of introduction regions electrically contacting the terminals of the first metal electrode layer and a channel region interposed between the introduction regions, an insulating layer disposed on the first metal electrode layer and the phase-change material layer, a via hole disposed on the first metal electrode layer, and a second metal electrode layer disposed to fill the via hole. The switch device performs memory operations using resistive heating of a phase-change material without an additional heater electrode, thereby minimizing thermal loss due to thermal conductivity of a metal electrode to reduce power consumption of the switch device.
