    摘要: A semiconductor memory device includes a first conductive line on a semiconductor substrate, an interlayer insulating layer on the first conductive line, a second conductive line on the interlayer insulating layer, and a memory cell in an hole through the interlayer insulating layer wherein the first and second conductive lines cross, the memory cell including a discrete resistive memory material region disposed in the hole and electrically connected between the first and second conductive lines. The resistive memory material region may be substantially contained within the hole. In some embodiments, contact between the resistive memory material region and the interlayer insulating layer is substantially limited to sidewalls of the interlayer insulating layer in the hole.

    摘要: Ferroelectric memory devices can be formed by polishing an insulating layer on a plurality of ferroelectric capacitors with a silica slurry to reduce a height of the insulating layer above a surface of the plurality of ferroelectric capacitors so that the surface remains covered by a portion of the insulating layer. The insulating layer can be further polished with a ceria slurry to further reduce the height of the insulating layer and to expose a polishing stop layer on the surface of the plurality of ferroelectric capacitors. Related devices are also disclosed.
