Integrated circuits with embedded memory structures and methods for fabricating the same

Abstract

Integrated circuits with embedded memory structures, and methods for fabricating integrated circuits are provided. An exemplary method for fabricating an integrated circuit includes forming first and second conductive interconnects over a semiconductor substrate. The method includes depositing a conductive material over the first conductive interconnect. Also, the method includes forming a memory structure over the conductive material, wherein the memory structure has an uppermost surface distanced from the first conductive interconnect by a first height. Further, the method includes forming an interlayer dielectric over the memory structure and forming a conductive via coupled to the second conductive interconnect, wherein the conductive via has a second height over the second conductive interconnect less than the first height. The method also includes forming first and second contact plugs through the interlayer dielectric. The first contact plug contacts the memory structure and the second contact plug contacts the conductive via.
