    摘要: A layer of phase change material with silicon or another semiconductor, or a silicon-based or other semiconductor-based additive, is formed using a composite sputter target including the silicon or other semiconductor, and the phase change material. The concentration of silicon or other semiconductor is more than five times greater than the specified concentration of silicon or other semiconductor in the layer being formed. For silicon-based additive in GST-type phase change materials, sputter target may comprise more than 40 at % silicon. Silicon-based or other semiconductor-based additives can be formed using the composite sputter target with a flow of reactive gases, such as oxygen or nitrogen, in the sputter chamber during the deposition.

    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.
