Title: Device and method for changing automatically channel list in mobile communication system
Inventor: CHOI SE RIM
IPC: H04B7/26
Filed: 2000-10-13
Abstract: PURPOSE: An apparatus and a method for automatically modifying a channel list in a mobile system are provided to previously prevent call disconnection or the inferiority of transmitting/receiving sensitivity by automatically changing a specific sub cell having a bad RF signal output gain state for another good sub cell. CONSTITUTION: A management diagnosis part outputs an output gain control signal to an interface part in order to measure the output gain value of a specific sub cell RF signal(S10). The interface part interfaces the output gain control signal to a control part(S20). Receiving the output gain control signal, the control part judges whether the management diagnosis part is executing a different function from the output gain measurement function of the specific sub cell(S30). If the management diagnosis part is not executing a different function, the control part outputs the output gain control signal to an RF output gain measuring part(S40). The RF output gain measuring part, receiving the output gain control signal, measures the output gain value of the specific sub cell RF signal and outputs it to the control part(S50). If the control part outputs the measured output gain value to the interface part(S60), the interface part outputs it to the management diagnosis part(S70). The management diagnosis part judges whether the measured output gain value is larger than the minimum reference gain value(S80). In case that the measured output gain value is larger than the minimum reference gain value, the management diagnosis part outputs a normal state signal to a BCP(Base Control Process)(S90). If the normal state signal is received, the BCP allocates a call to the specific sub cell(S100). However, if the measured output gain value is smaller than the minimum reference gain value, the management diagnosis part outputs an abnormal state signal to the BCP(S120). If the abnormal state signal is received from the management diagnosis part, the BCP modifies a channel list and allocates a call to the specific sub cell(S130).

Title: Plasma deposition apparatus and method for forming deposition layer using it
Inventor: LEE YUN JIK
IPC: H01L21/205
Filed: 2000-12-28
Abstract: PURPOSE: A plasma deposition equipment and a deposition film formation method using the same are provided to enhance the step coverage by connecting a power supply to a heater block. CONSTITUTION: A reacting gas is supplied to a spreader(24) through a gas inlet(25). The reacting gas consisted of TiCl4, Ar and H2 gas becomes the plasma by making the high frequency wave supply to the spreader through the operation of a high frequency wave generator(26). A deposition film is formed on a silicon wafer by applying the negative voltage to the power supply(100) connecting to the heater block(23). If the negative voltage is applied to the silicon wafer, the Ar and the H cation in the plasma are accelerated and collided to the silicon wafer. The collision transfers an addition energy excepting the thermal energy from the heater block to the silicon wafer. The H cation accelerated to the silicon wafer not perfectly reduces in the plasma and reduces TiClx absorbed to the silicon wafer. The reaction between the silicon wafer and Ti is promoted by the collision energy of the R cation. Thus, the more dense and excellent crystalline TiSix thin film is obtained at the same temperature rather than a conventional deposition method not applying the voltage to the substrate.
