Abstract: In a capacitor having a high dielectric constant, the capacitor includes a cylindrical lower electrode, a dielectric layer and an upper electrode. A metal oxide layer is formed on inner, top and outer surfaces of the lower electrode as the dielectric layer. A first sub-electrode is formed on a surface of the dielectric layer along the profile of the lower electrode and a second sub-electrode is continuously formed on the first sub-electrode corresponding to the top surface of the lower electrode, so an opening portion of the lower electrode is covered with the second sub-electrode. The first and second sub-electrodes include first and second metal nitride layers in which first and second stresses are applied, respectively. Directions of the first and second stresses are opposite to each other. Accordingly, cracking is minimized in the upper electrode with the high dielectric constant, thereby reducing current leakage.

Abstract: A method for performing data communication in a mobile communication system is disclosed. The method serves to increase channel efficiency by connecting and releasing channels in accordance with the presence/absence of control and traffic data transmitted during packet data communications. Transmission power and mobile terminal battery power are conserved by controlling outputs of a dedicated control channel and a pilot channel when data transmission is discontinued temporarily during data communications. The mobile communication system includes an active state in which user data is transmitted through a dedicated traffic channel and control messages are transmitted through a dedicated control channel. In accordance with the method, a transition is made from the active state to a first control hold state when there is no control or user data to transmit for a first preset time. In the first control hold state, the dedicated traffic channel is released while the dedicated control channel and a reverse pilot channel are maintained. A transition is made from the first control state to a second control hold state when there is no user or control data to transmit for a second preset time. In the second control hold state, which is a resource save sub-state, the transmission outputs of the dedicated control channel and reverse pilot channel are interrupted to conserve power.

Abstract: A CDMA communication system provides a dedicated control channel capable of efficiently communicating control messages between a base station and a mobile station. In a dedicated control channel transmission device, a controller determines a frame length of a message to be transmitted and outputs a frame select signal corresponding to the determined frame length. A message generator generates frame data of the message to be transmitted according to the frame select signal. A transmitter spreads the frame data and transmitting the spread frame data through a dedicated control channel. In a dedicated control channel reception device, a despreader despreads a received signal. A first message receiver deinterleaves and decodes the despread signal in a first frame length to output a first message, and detects a first CRC corresponding to the decoded signal. A second message receiver deinterleaves and decodes the despread signal in a second frame length to output a second message, and detects a second CRC corresponding to the decoded signal. A controller selects one of the first and second messages according to first and second CRC detection results.
