Abstract
Disclosed are a capacitor for semiconductor device capable of increasing storage capacitance and preventing leakage current, and method of manufacturing the same. According to the present invention. A lower electrode is formed on a semiconductor substrate. The lower electrode is surface-treated so as to prevent generation of a natural oxide layer. An amorphous TaON layer is, as a dielectric layer, deposited on the upper part of the lower electrode. Afterwards, the amorphous TaON layer is thermal-treated in a range of maintaining its amorphous state. Next, an upper electrode is formed on the upper part of the TaON layer.
