    摘要: A method of forming a cell memory structure including the step of planarizing an HDP/LDP oxide layer lying over a capacitor area. The method provides for the planarization of the cell storage node, good isolation between the transistor and storage node, reduced step height for the cell-transistor and has the potential for increasing the node capacitance (like DRAM storage node).

    摘要: A process for fabricating a capacitor under bit line (CUM), DRAM device, featuring increased capacitance, without increasing the aspect ratio for a dry etched, narrow diameter bit line contact hole, has been developed. The process features increasing the vertical space in a capacitor opening, needed to accommodate a capacitor structure with increased vertical dimensions, via selective removal of the top portions of the polysilicon plug structures exposed in the capacitor openings. The depth of a subsequent bit line contact hole, opened to a non-truncated polysilicon plug structure, is therefore not increased as a result of the increase capacitor depth, thus not resulting in an increased aspect ratio for the dry etched, narrow diameter bit line contact hole.

    摘要: Devices and methods for preventing capacitor leakage caused by sharp tip. The formation of sharp tip is avoided by a thicker bottom electrode which fully fills a micro-trench that induces formation of the sharp tip. Alternatively, formation of the sharp tip can be avoided by recessing the contact plug to substantially eliminate the micro-trench.

    摘要: A semiconductor device includes a group of capacitors and a trench. Each capacitor includes a first conductive material layer, a dielectric layer, and a second conductive material layer. The dielectric layer is located between the first and second conductive material layers. The first conductive material layer coats an inside surface of a cup-shaped opening formed in an insulating layer. The trench is formed in the insulating layer. The trench extends between and crosses each of the capacitors in the group. The dielectric layer and the second conductive material layer are formed over the first conductive material layer in the cup-shaped openings and over an inside surface of the trench. The second conductive material layer extends between the capacitors of the group via the trench. Also, the second conductive material layer forms top electrodes for the capacitors of the group.
