摘要： Disclosed are polysilazane, a method of synthesizing the polysilazane, a composition for manufacturing a semiconductor device, and a method of manufacturing a semiconductor device using the composition. The polysilazane is synthesized through a reaction, under a catalyst, between dichlorosilane, trichlorosilane, and ammonia added in a reaction solvent as a reactant. In this instance, a polystyrene conversion weight average molecular weight of the polysilazane is about 2,000 to 30,000.

摘要： A method for controlling operation modes of a medium access control layer by a mobile subscriber station in a broadband wireless access communication system including the mobile subscriber station and a serving base station providing service to the mobile subscriber station is provided. The method includes the steps of: mode-transiting into an idle mode when there is no data transmission between the serving base station and the mobile subscriber station during a predetermined first time interval in an awake mode; detecting movement of the mobile subscriber station in the idle mode into another paging zone covering a target base station, which is different from a paging zone covering the serving base station; and mode-transiting into the awake mode and performing location update together with the target base station when the movement of the mobile subscriber station is detected.

摘要： There is provided a method of transmitting power control information to a BSC (Base Station Controller) in a BTS (Base station Transitive System) of a mobile communication system. The BTS receives forward power control (FPC) mode information indicating a slow power control from the BSC and transmits the FPC mode information to an MS (Mobile Station). The BATS extracts an EIB (Erasure Indicator Bit) that is a power control command in a frame period from a reverse pilot channel received from the MS according to the FPC mode information, determines the status of the EIB, and transmits a reverse SCH (Supplemental Channel) message including the EIB status information to the BSC.
