  • Patent number: 9472690
    Abstract: The present disclosure provides a deep trench capacitor device. A first capacitor electrode is made up of a doped region of semiconductor substrate in which two or more trenches are arranged. A second capacitor electrode is made up of a continuous body of conductive material. The continuous body of conductive material includes a lower body portion filling the two or more trenches and an upper body portion extending continuously over the lower body portion. The upper body portion extends upwardly out of the trenches by a non-zero distance. A capacitor dielectric liner is arranged in the two or more trenches to separate the first and second capacitor electrodes. The capacitor dielectric liner extends continuously out of the two or more trenches along outer sidewalls of the upper body portion.

  • Patent number: 9012296
    Abstract: A method for forming a trench capacitor includes providing a substrate of a semiconductor material having a hard mask layer; etching the hard mask layer and the substrate to form at least one trench extending into the substrate; and performing pull-back etching on the hard mask layer. In the pull-back etching, a portion of the hard mask layer defining and adjacent to side walls of an opening of the at least one trench is removed. A resulting opening on the hard mask layer has a width dimension larger than a width dimension of an opening of the at least one trench extending into the substrate. The method further comprises doping the semiconductor material defining upper surfaces and sidewalls of the at least one trench to form a doped well region.

  • Patent number: 8853048
    Abstract: The present disclosure provides a streamlined approach to forming vertically structured devices such as deep trench capacitors. Trenches and a contact plate bridging the trenches are formed using one lithographic process. A hard mask is formed over the substrate and etched through the mask to form two or more closely spaced trenches. The hard mask is then reduced by an isotropic etch process. The etch removes the hard mask preferentially between the trenches. Chemical mechanical polishing removes the conductive material down to the remaining hard mask layer, whereby conductive material remains in mask openings and forms a conductive bridge across the trenches.
