  • Patent number: 7772101
    Abstract: A phase-change memory device and a fabrication method thereof, capable of reducing driving current while minimizing a size of a contact hole used for forming a PN diode in the phase-change memory device that employs the PN diode. The method of fabricating the phase-change memory device includes the steps of preparing a semiconductor substrate having a junction area formed with a dielectric layer, forming an interlayer dielectric layer having etching selectivity lower than that of the dielectric layer over an entire structure, and forming a contact hole by removing predetermined portions of the interlayer dielectric layer and the dielectric layer. The contact area between the PN diode and the semiconductor substrate is increased so that interfacial resistance is reduced.
