    摘要: A storage cell, integrated circuit (IC) chip with one or more storage cells that may be in an array of the storage cells and a method of forming the storage cell and IC. Each storage cell includes a stylus, the tip of which is phase change material. The phase change tip may be sandwiched between an electrode and conductive material, e.g., titanium nitride (TiN), tantalum nitride (TaN) or n-type semiconductor. The phase change layer may be a chalcogenide and in particular a germanium (Ge), antimony (Sb), tellurium (Te) (GST) layer.

    摘要: The present invention includes a method for forming a phase change material memory device and the phase change memory device produced therefrom. Specifically, the phase change memory device includes a semiconductor structure including a substrate having a first doped region flanked by a set of second doped regions; a phase change material positioned on the first doped region; and a conductor positioned on the phase change material, wherein when the phase change material is a first phase the semiconductor structure operates as a bipolar junction transistor, and when the phase change material is a second phase the semiconductor structure operates as a field effect transistor.

    摘要: A stylus, an integrated circuit (IC) and method of forming the IC. The stylus extends upward from its apex and has a substantially circular cross section that decreases in diameter upward from the apex. The stylus is formed in a mold that may be formed in an orifice in a dielectric layer between wiring layers. The mold may include multiple concentric layers. For a more pronounced, non-linear stylus taper, each layer may be thinner than its next adjacent outer concentric layer.

    摘要: Disclosed are a semiconductor structure and a method that allow for simultaneous voltage/current conditioning of multiple memory elements in a nonvolatile memory device with multiple memory cells. The structure and method incorporate the use of a resistor connected in series with the memory elements to limit current passing through the memory elements. Specifically, the method and structure incorporate a blanket temporary series resistor on the wafer surface above the memory cells and/or permanent series resistors within the memory cells. During the conditioning process, these resistors protect the transition metal oxide in the individual memory elements from damage (i.e., burn-out), once it has been conditioned.
