Abstract
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 Ta O 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 Ta O when depositing Ta O 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.
