    摘要: Provided are semiconductor devices having a system-on-chip (SOC) configuration that combines both a capacitor-based cell-array memory region and one or more MOS core/peripheral circuit/logic regions on a single chip and a method for manufacturing such devices. The manufacturing process reduces the number of additional photolithographic processes required and modifies the relationship between the sizing of various layers and/or structures to reduce the fabrication cost and improve the reliability of the resulting devices. In particular, the capacitors for the memory region are formed in the same insulating layer as the first metal pattern for the core/peripheral circuit/logic regions of the devices, thereby producing capacitors and metal patterns of substantially the same height and thickness respectively. A landing structure may also be formed in the cell array region in combination with the first metal pattern for improving the contact process in the cell array region.

    摘要: An integrated circuit memory device includes a memory cell array comprising memory cells having respective data storage regions therein, a plurality of pass transistors having different channel widths and/or channel lengths, and a plurality of conductive lines. Each of the conductive lines electrically couple a respective one of the pass transistors to ones of the memory cells. Each of the memory cells has a line resistance defined by a portion of the corresponding one of the conductive lines extending between the memory cell and the pass transistor coupled thereto. Ones of the memory cells having greater line resistances are coupled to ones of the pass transistors having greater channel widths and/or shorter channel lengths than ones of the memory cells having smaller line resistances. Each of the memory cells may also include a diode therein, and ones of the memory cells having greater line resistances may include diodes having lower resistances. Related devices are also discussed.
