  • Publication number: 20120292585
    Abstract: 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.

  • Publication number: 20090029555
    Abstract: Multi-step selective etching. Etching an unmasked region associated with each layer of a plurality of layers, the plurality of layers comprising a stack, wherein the unmasked region of each of the plurality of layers is etched while exposed to a temperature, a pressure, a vacuum, using a plurality of etchants, wherein at least one of the plurality of etchants comprises an inert gas and oxygen, wherein the etchant oxidizes the at least one layer that can be oxidized such that the etching stops, the plurality of etchants leaving substantially unaffected a masked region associated with each layer of the plurality of layers, wherein two or more of the plurality of layers comprises a memory stack, and preventing corrosion of at least one of the plurality of layers comprising a conductive metal oxide by supplying oxygen to the stack after etching the unmasked region without breaking the vacuum.
