摘要： The present invention discloses a method of manufacturing a capacitor in a semiconductor device which is directed to solve the problem of reduction of capacitance occurring when manufacturing a capacitor of a MIS structure using poly-silicon as an underlying electrode and metal as an upper electrode in a capacitor using Ta2O5 as a dielectric film. In order to solve the problem, the present invention forms an underlying electrode using metal having a good oxide-resistant such as TiSiN. Thus, the present invention could not only lower the thickness of the effective oxide film of Ta2O5 when depositing Ta2O5 or performing a thermal process for crystallization but also prevent increase of a leak current due to oxidization of the underlying electrode and the diffusion prevention film, thus securing the capacitance of the capacitor and improving the electric characteristic of the capacitor.

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.
