    摘要： The present invention provides a method to fabricate an organic memory device, wherein the fabrication method includes forming a lower electrode, depositing a passive material over the surface of the lower electrode, applying an organic semiconductor material over the passive material, and operatively coupling the an upper electrode to the lower electrode through the organic semiconductor material and the passive material. Patterning of the organic semiconductor material is achieved by depositing a silicon-based resist over the organic semiconductor, irradiating portions of the silicon-based resist and patterning the silicon-based resist to remove the irradiated portions of the silicon-based resist. Thereafter, the exposed organic semiconductor can be patterned, and the non-irradiated silicon-based resist can be stripped to expose the organic semiconductor material that can be employed as a memory cell for single and multi-cell memory devices. A partitioning component can be integrated with the memory device to facilitate stacking memory devices and programming, reading, writing and erasing memory elements.

    摘要： A methodology for forming a memory cell is disclosed, wherein an organic polymer layer is formed over a conductive layer and an electrode layer is formed over the organic polymer layer. 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.

    摘要： The present invention provides a method for selectively removing anti-reflective coating (ARC) from the surface of an dielectric layer over the surface of a substrate without scratching the dielectric layer and/or tungsten contacts formed therein. In one embodiment, a fluoromethane (CH3F)/oxygen (O2) etch chemistry is used to selectively remove the ARC layer without scratching and/or degradation of the dielectric layer, source/drain regions formed over the substrate, and a silicide layer formed atop stacked gate structures. The CH3F/O2 etch chemistry etches the ARC layer at a rate which is significantly faster than the etch rates of the dielectric layer, the source/drain regions and the silicide layer. In addition, by removing the ARC layer prior to the formation of tungsten contacts by filling of contact openings formed in the dielectric layer with tungsten, potential scratching of tungsten contacts due to ARC layer removal is eliminated.

    摘要： The present invention leverages an etch-back process to provide an electrode cap for a polymer memory element. This allows the polymer memory element to be formed within a via embedded in layers formed on a substrate. By utilizing the etch-back process, the present invention provides tiny electrical contacts necessary for the proper functioning of polymer memory devices that utilize the vias. In one instance of the present invention, one or more via openings are formed in a dielectric layer to expose an underlying layer. A polymer layer is then formed within the via on the underlying layer with a top electrode material layer deposited over the polymer layer, filling the remaining portion of the via. Excess portions of the top electrode material are then removed by an etching process to form an electrode cap that provides an electrical contact point for the polymer memory element.

    摘要： A method for shrinking a semiconductor device and minimizing auto-doping problem is disclosed. An etch stop layer is eliminated and is replaced with a consumable liner oxide layer so that stacked gate structures of the device can be positioned closer together, thus permitting shrinking of the device. The liner oxide layer is formed directly over a substrate and in contact with stacked gate structures, sidewall spacers, and sources and drains formed on the substrate, and serves as an auto-doping barrier for the dielectric layer to prevent boron and phosphorous formed in the dielectric layer from auto-doping into the sources and drains.
