    摘要: In some aspects, a memory cell is provided that includes a steering element, a metal-insulator-metal (“MIM”) stack coupled in series with the steering element, and a conductor above the MIM stack. The MIM stack includes a resistance switching element and a top electrode disposed on the resistance switching element, and the top electrode includes a highly doped semiconductor material. The memory cell does not include a metal layer between the MIM stack and the conductor. Numerous other aspects are provided.

    摘要: A method of making a device is disclosed including: forming a first hard mask layer over an underlying layer; forming a first imprint resist layer over the underlying layer; forming first features over the first hard mask layer by bringing a first imprint template in contact with the first imprint resist layer; forming a first spacer layer over the first features; etching the first spacer layer to form a first spacer pattern and to expose top of the first features; removing the first features; patterning the first hard mask, using the first spacer pattern as a mask, to form first hard mask features; and etching at least part of the underlying layer using the first hard mask features as a mask.
