20100319962 | SELF-ALIGNED NANO-SCALE DEVICE WITH PARALLEL PLATE ELECTRODES - A contiguous deep trench includes a first trench portion having a constant width between a pair of first parallel sidewalls, second and third trench portions each having a greater width than the first trench portion and laterally connected to the first trench portion. A non-conformal deposition process is employed to form a conductive layer that has a tapered geometry within the contiguous deep trench portion such that the conductive layer is not present on bottom surfaces of the contiguous deep trench. A gap fill layer is formed to plug the space in the first trench portion. The conductive layer is patterned into two conductive plates each having a tapered vertical portion within the first trench portion. After removing remaining portions of the gap fill layer, a device is formed that has a small separation distance between the tapered vertical portions of the conductive plates. | 12-23-2010 |
20110042731 | STRUCTURE AND METHOD OF FORMING ENHANCED ARRAY DEVICE ISOLATION FOR IMPLANTED PLATE EDRAM - A method for forming a memory device in a semiconductor on insulator substrate is provided, in which a protective oxide that is present on the sidewalls of the trench protects the first semiconductor layer, i.e., SOI layer, of the semiconductor on insulator substrate during bottle etching of the trench. In one embodiment, the protective oxide reduces back channel effects of the transistors to the memory devices in the trench that are formed in the semiconductor on insulator substrate. In another embodiment, a thermal oxidation process increases the thickness of the buried dielectric layer of a bonded semiconductor on insulator substrate by oxidizing the bonded interface between the buried dielectric layer and at least one semiconductor layers of the semiconductor on insulator substrate. The increased thickness of the buried dielectric layer may reduce back channel effects in devices formed on the substrate having trench memory structures. | 02-24-2011 |
