摘要： A programmable phase change material (PCM) structure includes a heater element formed at a BEOL level of a semiconductor device, the BEOL level including a low-K dielectric material therein; a first via in electrical contact with a first end of the heater element and a second via in electrical contact with a second end of the heater element, thereby defining a programming current path which passes through the first via, the heater element, and the second via; a PCM element disposed above the heater element, the PCM element configured to be programmed between a lower resistance crystalline state and a higher resistance amorphous state through the use of programming currents through the heater element; and a third via in electrical contact with the PCM element, thereby defining a sense current path which passes through the third via, the PCM element, the heater element, and the second via.
