    摘要: In formation of monolithic three dimensional memory arrays, a photomask may be used more than once. Reuse of a photomask creates second, third or more instances of reference marks used by the stepper to achieve alignment (alignment marks) and to measure alignment achieved (overlay marks) directly above prior instances of the same reference mark. The prior instances of the same reference mark may cause interference with the present instance of the reference mark, complicating alignment and measurement. Using the methods of the present invention, blocking structure is created vertically interposed between subsequent instances of the same reference mark, preventing interference.

    摘要: A reverse bias trim operation for the reset state of a non-volatile memory system is disclosed. Non-volatile memory cells including a resistance change element undergo a reverse bias reset operation to change their resistance from a set state at a first level of resistance to a reset state at a second level of resistance. Certain memory cells in a set of cells that was reset may be deeply reset to a level of resistance beyond a target level for the reset state. A second reverse bias is applied to the set of memory cells to move the resistance of each cell that was deeply reset toward the target level of the reset state. A smaller reverse bias than used for the reset operation can shift the resistance of the cells back toward the set level and out of their deeply reset condition. The operation is self-limiting in that cells stop their resistance shifts upon reaching the target level. Cells that were not deeply reset are not affected.

    摘要: A passive element memory device is provided that includes memory cells comprised of a state change element in series with a steering element. Controlled pulse operations are used to perform resistance changes associated with set and reset operations in an array of memory cells. Selected memory cells in an array are switched to a target resistance state in one embodiment by applying a positive voltage pulse to selected first array lines while applying a negative voltage pulse to selected second array lines. An amplitude of voltage pulses can be increased while being applied to efficiently and safely switch the resistance of cells having different operating characteristics. The cells are subjected to reverse biases in embodiments to lower leakage currents and increase bandwidth. The amplitude and duration of voltage pulses are controlled, along with the current applied to selected memory cells in some embodiments. These controlled pulse-based operations can be used to set memory cells to a lower resistance state or reset memory cells to a higher resistance state in various embodiments.

    摘要: In the present invention a metal oxide or nitride compound which is a wide-band-gap semiconductor abuts a silicon, germanium, or alloy of silicon and/or germanium of the opposite conductivity type to form a p-n heterojunction. This p-n heterojunction can be used to advantage in various devices. In preferred embodiments, one terminal of a vertically oriented p-i-n heterojunction diode is a metal oxide or nitride layer, while the rest of the diode is formed of a silicon or silicon-germanium resistor; for example a diode may include a heavily doped n-type silicon region, an intrinsic silicon region, and a nickel oxide layer serving as the p-type terminal. Many of these metal oxides and nitrides exhibit resistivity-switching behavior, and such a heterojunction diode can be used in a nonvolatile memory cell, for example in a monolithic three dimensional memory array.
