Abstract:
A phase change memory (PCM) cell with a low deviation contact area between a heater and a phase change element is provided. The PCM cell comprises a bottom electrode, a dielectric layer, a heater, a phase change element, and a top conductive. The dielectric layer overlies the bottom electrode. The heater extends upward from the bottom electrode, through the dielectric layer. Further, the heater has a top surface that is substantially planar and that is spaced below a top surface of the dielectric layer. The phase change element overlies the dielectric layer and protrudes into the dielectric layer to contact with the top surface of the heater. Also provided is a method for manufacturing the PCM cell.

Claim (Index 1):
A phase change memory (PCM) structure comprising:\n a bottom electrode; a dielectric layer overlying the bottom electrode; a heater extending upward from the bottom electrode, through the dielectric layer, wherein the heater has a top surface that is substantially planar and that is spaced below a top surface of the dielectric layer; and a phase change element overlying the dielectric layer and protruding into the dielectric layer to contact with the top surface of the heater.
