Abstract
Methods for forming an integrated circuit are provided. Aspects include providing a wafer substrate having an embedded memory area interconnect structure and an embedded non-memory area interconnect structure, the memory area interconnect structure comprising metal interconnects formed within a first interlayer dielectric, recessing a portion of the memory area interconnect structure, forming a bottom electrode contact on the recessed portion of the memory area interconnect structure, forming a bottom electrode over the bottom electrode contact, forming a protective dielectric layer over the non-memory area interconnect structure, and forming memory element stack layers on a portion of the bottom electrode.
