    摘要: A coupling capacitor and a semiconductor memory device using the same are provided. In an embodiment, each memory cell of the semiconductor memory device includes a coupling capacitor so that a storage capacitor can store at least 2 bits of data. The coupling capacitor has a capacitance having a predetermined ratio with respect to the capacitance of the storage capacitor. For this, the coupling capacitor is formed by substantially the same fabrication process as the storage capacitor. The predetermined ratio is obtained by choosing an appropriate number of individual capacitors, each with the same capacitance of the storage capacitor, to comprise the coupling capacitor. Also, the coupling capacitor is disposed on an interlayer insulating layer that buries a bit line in a cell region and a sense amplifier in a sense amplifier region.

    摘要: A CMOS semiconductor device and a method of manufacturing the same in which the gate induced drain leakage (GIDL) effect is reduced. In the semiconductor device of this invention, high concentration source/drain regions of a PMOS transistor are formed away from the gate pattern sidewall spacers. This is accomplished by using as an implant mask a dielectric film formed on an entire surface of a semiconductor substrate, where the semiconductor substrate includes a PMOS transistor region in an n-well, a low concentration source/drain regions of a PMOS transistor formed by using a gate pattern as an implant mask, the PMOS transistor gate pattern sidewall spacers, and an NMOS transistor region in a p-well with the NMOS transistor having both a low concentration and a high concentration source/drain regions.

    摘要: A method for fabricating a semiconductor device, wherein a dual damascene metal line is formed utilising a material layer pattern. The material layer pattern has openings to define contact holes both for metal interconnection in the peripheral region and for storage nodes in the cell array region. The material layer pattern is formed on an insulating layer. A second insulating layer is deposited on the material layer pattern. A groove mask pattern is formed and used as an etch stop while etching through the etching is performed at the another insulating layer and stopped at the material layer to form a first opening. Using the material layer pattern, exposed portions of the insulating layer are etched to form a second opening aligned to the first opening and thereby to form a dual damascene opening for a metal line. Metal is deposited in the first and second opening to form dual damascene metal lines.
