A capacitor for use in a semiconductor device, a method of fabricating the capacitor, and an electronic device adopting the capacitor, wherein the capacitor includes upper and lower electrodes, each formed of a platinum group metal; a thin dielectric layer disposed between the upper and lower electrodes; and a buffer layer disposed between the lower electrode and the thin dielectric layer, the buffer layer including a metal oxide of Group 3, 4, or 13. In an embodiment, the method of fabricating includes absorbing CO on a surface of a lower electrode of a platinum group metal, placing the lower electrode under a reducing atmosphere to produce a lattice oxygen, using the lattice oxygen to form a thin dielectric layer by performing an ALD process using a precursor for the thin dielectric layer, and forming an upper electrode of a platinum group metal on the thin dielectric layer.

An amorphous high-k thin film for a semiconductor device and a manufacturing method thereof are provided. The amorphous high-k thin film includes Bi, Ti, Al, and O. Since a BTAO based amorphous dielectric thin film is used as a dielectric material of a DRAM capacitor, a dielectric constant is more than 25, and an increase of a leakage current caused in reducing a physical thickness of the dielectric thin film can be prevented. Accordingly, it is very useful for the integration of the semiconductor device.
