Abstract: PURPOSE: A method for fabricating a MOS transistor is provided to prevent a concentration of an electric field on a lower side edge of a gate and a short channel effect. CONSTITUTION: A gate oxide layer(2), a polysilicon layer(3), a tungsten silicide layer(4) and a nitride layer(5) are deposited in sequence on a substrate(1). The nitride layer(5) and the tungsten silicide layer(4) are then selectively etched to expose a portion of the polysilicon layer(3). The exposed polysilicon layer(3) is taperingly etched so that a gate electrode has a lower part smaller than an upper part. The exposed gate oxide layer(2) is then etched, so the gate electrode is obtained. Thereafter, a lightly doped source and drain(6) is formed in the substrate(1), and a sidewall spacer(7) is formed on a side of the gate electrode. In addition, a heavily doped source and drain(8) is formed in the substrate(1) around the sidewall spacer(7). Since the gate electrode has a sloped sidewall and a shortened lower part, a concentration of an electric field on a lower side edge of the gate electrode is reduced.

Abstract: PURPOSE: A managing method of a work station processor interworking with a switching system is provided for an operator to quickly recognize an operation status of an internal processor of a work processor to instantly and effectively cope with an error in its occurrence to smoothly operate a work station by monitoring the processor of the work station existing outside a switching system by an SSC(System Status Control) and informing the operator of it. CONSTITUTION: An SSC of a switching system transmits the first signal requesting current status information to a processor, and determines the status of the processor depending on whether it receives a response signal to the first signal from the processor(S22). At this time, an operation mode processor receives the first signal from the SSC and transmits the status information related to the current operation mode and a standby mode. In case that a response signal to the first signal is received from the processor of the work station, the SSC analyzes the received data, records the status information of the processor in a data base(S23), and judges whether the processor responded to the first signal is a processor being operated by interworking with the current switching system(S24) . If it is the processor being operated by interworking with the current switching system, the SSC stores the status information of the corresponding processor in the data base(S25). If no response signal to the first signal is received from the processor, the SSC determines that a corresponding processor has not been installed and transmits a work station processor installation signal to an operator(S26).
