    摘要: A storage capacitor includes a first capacitor portion and a second capacitor portion, the second capacitor portion being disposed above the first capacitor portion, thereby defining a first direction. The first and the second portions each include a hollow body made of a conductive material, respectively, thereby forming a first capacitor electrode. An upper diameter of each of the hollow bodies is larger than a lower diameter of the hollow body, the diameter being measured perpendicularly with respect to the first direction. The storage capacitor also includes a second capacitor electrode and a dielectric material disposed between the first and the second capacitor electrodes. The storage capacitor also includes an insulating material disposed outside the hollow bodies, and a layer of an insulating material. A lower side of the insulating layer is disposed at a height of an upper side of the first capacitor portion.

    摘要: A transistor array for semiconductor memory devices is provided. A plurality of semiconductor pillars extending outwardly from a bulk section of a semiconductor substrate is arranged in rows and columns. Each pillar forms an active area of a vertical channel access transistor. Insulating trenches are formed between the rows of pillars. Buried word lines extend within the insulating trenches along the rows of pillars. Bit line trenches are formed between columns of pillars. Bit lines extend perpendicular to the word lines in lower portions of the bit line trenches. A first and a second column of pillars face adjacent each bit line. Each bit line is coupled to the active areas in the pillars of the first column of pillars via a single sided bit line contact formed from polycrystalline silicon and is insulated from the active areas of the pillars of the second column of pillars.
