The method and system includes implanting first low-dose arsenic into an area in the substrate, thermally diffusing the first low-dose arsenic through a portion of the substrate, implanting a second higher-dose arsenic into the area in the substrate, and diffusing the second higher-dose arsenic into the area in the substrate. Under the present invention, the combination of the first and second arsenic implants has a graded lateral profile which reduces band-to-band tunneling current and short-channel effects. The method also improves the reliability and performance of the semiconductor devices.

    摘要: The invention facilitates manufacture of semiconductor memory components by reducing the number of layers required to implement a semiconductor memory device. The invention provides for a selection element to be formed in the same layer as one of the control lines (e.g. one of the wordline and bitline). In one embodiment of the invention, a diode is implemented as the selection element within the same layer as one of the control lines. Production of the selection element within the same layer as one of the wordline and bitline reduces problems associated with vertical stacking, increases device yield and reduces related production costs. The invention also provides an efficient method of producing memory devices with the selection element in the same layer as one of the control lines.

    摘要: One embodiment of the invention relates to a method for refreshing a nonvolatile memory array. In the method, a threshold voltage of a multi-bit memory cell is analyzed to determine if it has drifted outside of a number of allowable voltage windows, wherein each allowable voltage windows corresponds to a different multi-bit value. If the threshold voltage of the cell has drifted outside of the number of allowable voltage states, then the cell is recovered by adjusting at least one voltage boundary of at least one of the number of allowable voltage states.

    摘要: The present invention provides a planar polymer memory device that can operate as a non-volatile memory device. A planar polymer memory device can be formed with two or more electrodes and an electrode extension associated with one electrode, wherein a selectively conductive medium and dielectric separate the electrodes. The method for forming a planar polymer memory device comprises at least one of forming a first electrode with an associated plug, forming a second electrode, forming a passive layer over the extension, depositing an organic polymer and patterning the organic polymer. The method affords integration of a planar polymer memory device into a semiconductor fabrication process. A thin film diode (TFD) can further be employed with a planar polymer memory device to facilitate programming. The TFD can be formed between the first electrode and the selectively conductive medium or the second electrode and the selectively conductive medium.

A first via is etched into the electrode and organic polymer layers, and a dielectric material is applied over the stack to at least fill in the first via. A second via is then etched into the dielectric material so as to expose and make the electrode layer available as a top electrode. A wordline is then formed over the dielectric material such that the top electrode is connected to the wordline by way of the second via. A memory device formed in accordance with the disclosed methodology includes a top electrode formed over an organic polymer layer, a conductive layer under the organic polymer layer, a via defined by a dielectric material and located above the top electrode, and a wordline formed over the dielectric material such that the top electrode is connected to the wordline by way of the via.
