    摘要: Method for manufacturing polycrystalline silicon having high resistance, having a first step for depositing a polycrystalline silicon layer for a resistor area over a silicon semiconductor substrate; a second step for growing a first thermal oxide layer having a first specified depth over the polycrystalline silicon layer, ion-implanting with the nitrogen thereon, and growing a second thermal oxide layer having a second specified depth on the ion-implanted layer; a third step for forming a resistor pattern of the polycrystalline silicon with a photo etching method; and a fourth step for ion-implanting impurities in order to decrease the resistance of the polycrystalline silicon as contact regions to be used in resistance contacts with a fixed semiconductor region on the substrate.

    摘要: A memory cell device having circuitry located between memory cell arrays comprises power and ground lines to the circuitry formed directly above the memory cell arrays. The power and ground lines are parallel and positioned in an adjacent alternating pattern such that a power line is positioned adjacent a ground line, which is positioned adjacent another power line and so on. Signal lines carrying signals to and from the circuitry are also formed directly above memory cell arrays.
