    摘要: A memory cell includes a memory cell layer with a first dielectric layer over a bottom electrode layer, a second dielectric layer over the first dielectric layer, and a top electrode over the second dielectric layer. The dielectric layers define a via having a first part bounded by the first electrode layer and the bottom electrode and a second part bounded by the second dielectric layer and the top electrode. A memory element is within the via and is in electrical contact with the top and bottom electrodes. The first and second parts of the via may comprise a constricted, energy-concentrating region and an enlarged region respectively. The constricted region may have a width smaller than the minimum feature size of the process used to form the enlarged region of the via. A method for manufacturing a memory cell is also disclosed.

    摘要: Memory cells are described along with methods for manufacturing. A memory cell described herein includes a bottom electrode, a top electrode overlying the bottom electrode, a via having a sidewall extending from a bottom electrode to a top electrode, and a memory element electrically coupling the bottom electrode to the top electrode. The memory element has an outer surface contacting a dielectric sidewall spacer that is on the sidewall of the via, and comprises a stem portion on the bottom electrode and a cup portion on the stem portion. A fill material is within an interior defined by an inner surface of the cup portion of the memory element.

    摘要: A memory cell device, including a memory material element switchable between electrical property states by the application of energy, includes depositing an electrical conductor layer, depositing dielectric material layers and etching to create a first electrode and voids. A memory material is applied into a void to create a memory material element in contact with the first electrode. A second electrode is created to contact the memory material element.
