    摘要: A semiconductor structure includes a first III-V compound layer. A second III-V compound layer is disposed on the first III-V compound layer and is different from the first III-V compound layer in composition. A carrier channel is located between the first III-V compound layer and the second III-V compound layer. A source feature and a drain feature are disposed on the second III-V compound layer. A gate electrode is disposed over the second III-V compound layer between the source feature and the drain feature. A fluorine region is embedded in the second III-V compound layer under the gate electrode. A gate dielectric layer is disposed over the second III-V compound layer. The gate dielectric layer has a fluorine segment on the fluorine region and under at least a portion of the gate electrode.

    摘要: A manufacture method of a multilevel phase-change memory and operating method thereof are provided. The method includes providing a substrate, forming a bottom electrode on the substrate, forming a first heating layer on top of the bottom electrode, forming a second heating layer on top of the first heating layer, forming a first phase-change layer and a second phase-change layer respectively on the first heating layer and the second heating layer, and forming a first top electrode and a second electrode respectively on the first phase-change layer and the second phase-change layer. Hence, the bottom electrode, the first heating layer and the first phase-change layer constitute an electrical current path, the bottom electrode, the first heating layer, the second heating layer and the second phase-change layer constitute another electrical current path, and the resistances of the two electrical current path are different, thereby increasing the memory density.
