    摘要: A contact structure in a semiconductor device and a method of forming the same are provided. The contact structure includes a lower interconnection having a capacitor upper electrode of memory cells; an interlayer dielectric layer formed on the lower interconnection and having a contact hole that exposes a portion of the lower interconnection; and an upper interconnection formed on the interlayer dielectric layer and electrically connected to the lower interconnection through the contact hole. The lower portion of the lower interconnection has a larger width than the bottom of the contact hole and extends downward or below the bottom of the contact hole so that the lower interconnection has a T-shape in cross-section. With these structures, the lower interconnection can be prevented from being pierced when the contact holes are formed. Consequently, stable and uniform contact resistance can be obtained.
