摘要： Forming a capacitor of a semiconductor device includes forming an interlayer dielectric having holes over a semiconductor substrate. A conductive layer is then formed on surfaces of the holes and on the upper surface of the interlayer dielectric. A silicon-containing conductive layer is formed by flowing a silicon source gas for the semiconductor substrate formed with the conductive layer, so that silicon atoms can penetrate into the conductive layer. The silicon-containing conductive layer prevents etchant from infiltrating the interlayer dielectric below the silicon-containing conductive layer.

摘要： A capacitor is made by forming a buffer oxide layer, an etching stop layer, and a mold insulation layer over a semiconductor substrate having a storage node contact plug. The mold insulation layer and the etching stop layer are etched to form a hole in an upper portion of the storage node contact plug. A tapering layer is deposited over the mold insulation layer including the hole. The tapering layer and the buffer oxide layer are etched back so that the tapering layer is remained only at the upper end portion of the etched hole. A metal storage node layer formed on the etched hole over the remaining tapering layer. The mold insulation layer and the remaining tapering layer are removed to form a cylindrical storage node having a tapered upper end. A dielectric layer and a plate node are formed over the storage node.
