Abstract: PURPOSE: A wireless audio/video security system with a wireless phone is provided to monitor information, provided from a security system, by using a wireless phone and to store the monitored audio/video data if necessary. CONSTITUTION: A wireless audio/video security system with a wireless phone(10) is composed of the wireless phone(10), a camera part(30), and a wireless phone main body(20). The wireless phone(10), executing the ordinary functions of a wireless phone, receives and outputs the radio audio/video data transmitted from the camera part(30). The camera part(30) transmits audio/video data, based on calling or motion detection, to the wireless phone(10). The main body(20) executes the battery charging function of the wireless phone(10). In case that the wireless phone(10) works as an ordinary wireless phone, the main body(20) works as a base station. Also the main body(20) stores audio/video data, transmitted from the wireless phone(10), in a computer(40).

Abstract: PURPOSE: A method for fabricating a capacitor is provided to improve large capacitance and maintain a uniform characteristic by easily using a metal oxide with a large dielectric constant as a dielectric layer and by reducing a reaction between the dielectric layer and an electrode layer. CONSTITUTION: The first electrode layer includes a tantalum element and combination elements chemically combining with the tantalum element. The first electrode layer including a tantalum nitride is formed on a substrate(10) by using a tantalum precursor including ligand-combination elements wherein a part of the combination elements ligand-combines with the tantalum element. A dielectric layer is formed on the first electrode. The second electrode layer is formed on the dielectric layer.
