摘要： A structure for a memory device including a plurality of substantially planar thin-film layers or a plurality of conformal thin-film layers is disclosed. The thin-film layers form a memory element that is electrically in series with first and second cladded conductors and operative to store data as a plurality of conductivity profiles. A select voltage applied across the first and second cladded conductors is operative to perform data operations on the memory device. The memory device may optionally include a non-ohmic device electrically in series with the memory element and the first and second cladded conductors. Fabrication of the memory device does not require the plurality of thin-film layers be etched in order to form the memory element. The memory element can include a CMO layer having a selectively crystallized polycrystalline portion and an amorphous portion. The cladded conductors can include a core material made from copper.

摘要： Chemical mechanical polishing (CMP) of thin film materials using a slurry including a surfactant chemical operative to polish high portions of the film being planarized while preventing the polishing of low portions of the film is disclosed. The low portions can be in a step reduction region of a deposited film. The CMP process can be used for form a planar surface upon which subsequent thin-film layers can be deposited, such as an electrically conductive material for an electrode. The subsequently deposited thin-film layers are substantially planar as deposited without having to use CMP. The resulting thin-film layers are planar and have a uniform cross-sectional thickness that can be beneficial for layers of memory material for a memory cell. The processing can be performed back-end-of-the-line (BEOL) on a previously front-end-of-the-line (FEOL) processed substrate (e.g., silicon wafer) and the BEOL process can be used to fabricate two-terminal non-volatile cross-point memory arrays.
