    摘要: A magneto-resistive memory cell and a method of forming the memory cell, includes a substrate, a single crystalline semiconductor diode formed in the substrate; and a first thin film conductor recessed in the substrate, and a second thin film conductor formed above a magnetic tunnel junction formed on the diode. The diode and the first thin film conductor share a non-planar common surface, such that the metal tunnel junction is a predetermined distance from the thin film conductor.

    摘要: A method of forming integrated circuit chips including two dissimilar type NFETs and/or two dissimilar type PFETs on the same chip, such as both thick and thin gate oxide FETs. A DRAM array may be constructed of the thick oxide FETs and logic circuits may be constructed of the thin oxide FETs on the same chip. First, a gate stack including a first, thick gate SiO.sub.2 layer is formed on a wafer. The stack includes a doped polysilicon layer on the gate oxide layer, a silicide layer on the polysilicon layer and a nitride layer on the silicide layer. Part of the stack is selectively removed to re-expose the wafer where logic circuits are to be formed. A thinner gate oxide layer is formed on the re-exposed wafer. Next, gates are formed on the thinner gate oxide layer and thin oxide NFETs and PFETs are formed at the gates. After selectively siliciding thin oxide device regions, gates are etched from the stack in the thick oxide device regions. Finally, source and drain regions are implanted and diffused for the thick gate oxide devices.

    摘要: A resistance memory includes a resistance memory cell having a resistance memory element and a two-terminal access device in series. The two-terminal access device affects the current-voltage characteristic of the resistance memory cell. The resistance memory additionally includes a circuit to apply across the resistance memory cell a set pulse having a set polarity to set the resistance memory cell to a low-resistance state that is retained after application of the set pulse, a reset pulse having a reset polarity, opposite to the set polarity, to reset the resistance memory cell to a high-resistance state that is retained after application of the reset pulse, and a read pulse of the reset polarity and smaller in magnitude than the reset pulse to determine the resistance state of the resistance memory cell without changing the resistance state of the resistance memory cell.

    摘要: In a vertical-transistor based semiconductor structure, the problem of making a reliable electrical connection between the node of the deep trench capacitor and the lower electrode of the vertical transistor is solved by; depositing a sacrificial insulator layer, forming a vertical hardmask on the inner trench walls above the sacrificial insulator, then stripping the insulator to expose the substrate walls; diffusing dopant into the substrate walls to form a self-aligned extension of the buried strap; depositing the final gate insulator; and then forming the upper portion of the vertical transistor.

    摘要: A semiconductor MOSFET device is formed on a silicon substrate which includes trenches filled with Shallow Trench Isolation dielectric trench fill structures and extending above the surface of the substrate. The trench fill structures have protruding sidewalls with channel regions in the substrate having corner regions adjacent to the trench fill structures. The channel regions are between and adjacent to the STI trench fill structures doped with one concentration of dopant in the centers of the channel regions with a higher concentration of dopant in the corner regions. The dopant concentration differential provides a substantially equal concentration of electrons in the centers and at the corner regions of the channel regions.
