Abstract:
A phase change memory (PCM) cell with enhanced thermal isolation and low power consumption is provided. In some embodiments, the PCM cell comprises a bottom electrode, a dielectric layer, a heating element, and a phase change element. The dielectric layer is on the bottom electrode. The heating element extends through the dielectric layer, from a top of the dielectric layer to the bottom electrode. Further, the heating element has a pair of opposite sidewalls laterally spaced from the dielectric layer by a cavity. The phase change element overlies and contacts the heating element. An interface between the phase change element and the heating element extends continuously respectively from and to the opposite sidewalls of the heating element. Also provided is a method for manufacturing the PCM cell.

Claim (Index 9):
A method for manufacturing a phase change memory (PCM) cell, the method comprising:\n forming an opening in a dielectric layer, wherein the opening comprises a pair of opposite sidewalls defined by the dielectric layer; forming a spacer in the opening, wherein the spacer comprises a pair of spacer segments respectively lining the opposite sidewalls of the opening; forming a heating element filling the opening, wherein the heating element is spaced from the opposite sidewalls of the opening by the spacer, and wherein a top surface of the heating element extends continuously respectively from and to the spacer segments; removing the spacer to define a cavity in place of the spacer; and forming a phase change element overlying and contacting the heating element.
