Abstract:
Generally, the subject matter disclosed herein relates to the fabrication of an RRAM cell using CMOS compatible processes. A resistance random access memory device is disclosed which includes a semiconducting substrate, a top electrode, at least one metal silicide bottom electrode formed at least partially in the substrate, wherein at least a portion of the at least one bottom electrode is positioned below the top electrode, and at least one insulating layer positioned between the top electrode and at least a portion of the at least one bottom electrode. A method of making a resistance random access memory device is disclosed that includes forming an isolation structure in a semiconducting substrate to thereby define an enclosed area, performing at least one ion implantation process to implant dopant atoms into the substrate within the enclosed area, after performing the at least one ion implantation process, forming a layer of refractory metal above at least portions of the substrate, and performing at least one heat treatment process to form at least one metal silicide bottom electrode at least partially in the substrate, wherein at least a portion of the at least one bottom electrode is positioned below at least a portion of a top electrode of the device.
