  • Patent number: 6589846
    Abstract: An method for fabricating a semiconductor device reduces a size of a MOSFET by self aligning a gate electrode with a device isolation insulation film. Thus, the gate electrode is not overlapped with the device isolation insulation film, differently from a conventional method for forming a MOSFET by partially overlapping the gate electrode with the device isolation insulation film in consideration of misalignment and CD variations in a mask process. As a result, a size of the MOSFET is reduced, thereby efficiently achieving the high integration of the semiconductor device.

  • Patent number: 6372571
    Abstract: Provided is a method of manufacturing a semiconductor device having a stacked capacitor configured to reduce a step difference between a memory cell region and a logic circuit region adjacent thereto. In the method of manufacturing a semiconductor device, a sacrificial film removed after formation of the semiconductor device having a stacked capacitor, is preserved in the logic circuit region to be used as an interlayer insulating film. Thus, a step difference between a memory cell region having the capacitor and a logic circuit region, is removed, thereby facilitating formation of multi-layered interconnection wirings formed after forming the capacitor, and attaining fineness of the interconnection wirings.

  • Patent number: 6339240
    Abstract: In DRAM comprising a read pass transistor, a write pass transistor and a storage transistor, a depletion transistor is connected to a source of the storage transistor. On a part of the source and drain of the depletion transistor, by forming an impurity region of same conductivity as that of the substrate on which the transistors are formed, a substrate voltage applied to the substrate is supplied to the storage transistor through the depletion transistor. An additional metal wire for connecting the source of the storage transistor to Vss voltage (ground voltage or substrate voltage) terminal and a contact hole area for such metal wire are not required. Accordingly, a high integration of the semiconductor can be accomplished and a reduction of reliability thereof can be decreased.
