Claim 8:
9. A device comprising:
an inter-metal dielectric (IMD) layer over a substrate, wherein the IMD layer has a first thickness;
a bottom electrode within the IMD layer, wherein a bottom surface of the bottom electrode and a bottom surface of the IMD layer are coplanar, wherein the bottom electrode has a second thickness that is less than the first thickness;
a phase-change material (PCM) on the bottom electrode layer and within the IMD layer, wherein the PCM has a third thickness that is less than the first thickness, wherein the first thickness is greater than a sum of the second thickness and the third thickness; and
a top electrode extending over and physically contacting a top surface of the IMD layer and a top surface of the PCM.
