Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device that can be reduced in leakage current and can easily maintain and control characteristics of a capacitor having a voltage-nondependent capacitance, and to provide a method of manufacturing the device.  <P>SOLUTION: In the capacitor which is formed on a semiconductor substrate and uses TiN as an electrode and a metal oxide such as Ta<SB>2</SB>O<SB>5</SB>etc having a high dielectric constant as a dielectric film 12, aluminum oxide (Al<SB>2</SB>O<SB>3</SB>) films 32 and 33 and aluminum nitride (AlN) films 31 and 34 are formed the dielectric film 12 and between an upper electrode 13 or the dielectric film 12 or a lower electrode 11, or the upper. Since a layer which is in contact with the TiN electrode is made of AlN and the layer which is in contact with the dielectric film 12 is made of Al<SB>2</SB>O<SB>3</SB>, no oxide directly comes into contact with the TiN electrode. Consequently, the formation of a TiO<SB>x</SB>film that is a primary factor of causing the voltage fluctuation of the capacitance between the electrode and the dielectric film 12 is prevented. In addition, since the dielectric film 12 can be sandwiched between the Al<SB>2</SB>O<SB>3</SB>films 32 and 33 which are good-quality insulating films having large band gaps, leakage currents are reduced and the control of the characteristics of the capacitor becomes easier.  <P>COPYRIGHT: (C)2004,JPO
