  • Patent number: 6780715
    Abstract: A method is disclosed for fabricating an MDL (Merged DRAM Logic) semiconductor device, in which silicide is formed on a logic region and a memory region selectively for enhancing device reliability. The method includes the steps of (a) providing a substrate having a first region and a second region adjoining the first region, (b) forming a first gate forming material layer in the first region, (c) forming a second gate forming material layer in the first region having the first gate forming material layer formed therein and the second region, (d) selectively patterning the second gate forming material layer to form second gates in the second region and a boundary dummy pattern layer at a boundary area of the first and second regions, and (e) selectively patterning the first gate forming material layer to form first gates in the first region.

  • Patent number: 6573135
    Abstract: A method for manufacturing a semiconductor device having a first capacitor in a memory cell region and a second capacitor in a logic region is described. The method includes the steps of: a) forming an interlayer insulating layer on a blanket substrate; b) simultaneously forming a first opening portion and a second opening portion for the first capacitor and the second capacitor, respectively, by selectively etching the interlayer insulating layer; c) simultaneously forming bottom electrodes of the first capacitor and the second capacitor by forming a conductive layer within the first opening portion and the second opening portion; d) forming a dielectric layer on the bottom electrodes of the first capacitor and the second capacitor; and e) forming top electrodes of the first capacitor and the second capacitor on the dielectric layer.
