Abstract:
A semiconductor structure having a contact plug includes a substrate. A memory cell region and a peripheral circuit region are defined on the substrate. At least one memory cell is disposed on the substrate within the memory cell region. The memory cell includes a transistor and a capacitor structure. A first planar stacked dielectric layer covers the peripheral circuit region. The first planar stacked dielectric layer includes two first dielectric layers and a second dielectric layer. The first dielectric layer at the bottom of the first planar stacked dielectric layer extends to the memory cell region and covers the capacitor structure. A contact plug is disposed at the peripheral circuit region and penetrates the first planar stacked dielectric layer.

Claim (Index 15):
The fabricating method of a semiconductor structure with a contact plug of  claim 13 , further comprising:\n during the planarization process, removing the second stacked dielectric layer within the memory cell region entirely to form a second planar stacked dielectric layer; and after forming the second planar stacked dielectric layer, removing part of the first stacked dielectric layer to expose the first dielectric layer at the bottom of the first stacked dielectric layer.
