Abstract: PURPOSE: A capacitor and a semiconductor device are provided to have a high operational reliability by enabling a fabrication process of the capacitor to be proceeded under 700°C. CONSTITUTION: A lower electrode(1) has HSG(hemispherical grain) formed on the surface thereof. A dielectric film(2) is composed of silicon nitride and covers the surface of the lower electrode(1). An upper electrode(3) covers the dielectric film(2). In the prior art, an impurity-doped polysilicon was adopted for an upper electrode. In that case, the impurity-doped polysilicon did not function as an upper electrode when heat treated under 700°C. However, an upper electrode(3) of the invention is composed of metal or electrically conducting compound. So the upper electrode(3), even though formed under 700°C, can sufficiently function as an electrode.
