    • A semiconductor photomask set for producing wafer alignment accuracy in a semiconductor fabrication process. The photomask set produces an alignment mark that is accurate for subsequent fabrication after undergoing a dual field oxide (FOX) fabrication process. Prior arts methods have traditionally covered the alignment marks with layers of oxide material. The method includes the steps of: (a) providing a first photomask member having mask portions for forming a plurality of first field oxide regions on a first region of a semiconductor substrate and also having a mask portion for forming an alignment marker; (b) providing a second photomask member having mask portions for forming a plurality of second field oxide regions on a second region of the semiconductor substrate and also having mask portions delineated for covering any first field oxide regions and alignment marker formed by using the first photomask member; (c) forming the first field oxide regions and the alignment marker utilizing the first photomask member; (d) covering the formed first field oxide regions and the alignment marker with a photoresist material by utilizing the second photomask member; (e) forming the second field oxide regions after utilizing the second photomask member; (f) facilitating wafer alignment accuracy by removing the photoresist material and exposing the alignment marker; and (g) aligning a semiconductor wafer by utilizing the exposed alignment marker. The mask set can be used in conjunction with stepper wafer alignment tools and is especially useful in forming a memory semiconductor product capable of performing block data erasure operations. The exposed alignment marker facilitates checking and testing mask misalignment during the fabrication process.

    • The present invention provides a multi-cell organic memory device that can operate as a non-volatile memory device having a plurality of multi-cell structures constructed within the memory device. A lower electrode can be formed, wherein one or more passive layers are formed on top of the lower electrode. An Inter Layer Dielectric (ILD) is formed above the passive layers and lower electrode, whereby a via or other type relief is created within the ILD and an organic semiconductor material is then utilized to partially fill the via above the passive layer. The portions of the via that are not filled with organic material are filled with dielectric material, thus forming a multi-dimensional memory structure above the passive layer or layers and the lower electrode. One or more top electrodes are then added above the memory structure, whereby distinctive memory cells are created within the organic portions of the memory structure and activated (e.g., read/write) between the top electrodes and bottom electrode, respectively. In this manner, multiple storage cells can be formed within a singular organic structure thereby increasing memory device density and storage.
