Abstract: PURPOSE: A MOS transistor with a SiGe channel and a manufacturing method thereof are to utilize as a gate insulating layer a substance capable of being formed at a low temperature and having a high dielectric constant, thereby obtaining the MOS transistor with improved electrical properties. CONSTITUTION: A SiGe channel layer(120) is formed on an active region in a semiconductor substrate(100) of a first conductive type. An aluminum oxide layer(140) is formed on the SiGe channel layer as a gate insulating layer. A gate conductive layer(150) is then formed on the aluminum oxide layer. The aluminum oxide layer and a portion of the gate conductive layer is removed, to form an aluminum oxide layer pattern and a gate conductive layer pattern exposing a part of a surface of the SiGe channel layer. Impurity ions are implanted into the exposed surface of the semiconductor substrate to form a source/drain region(130) of the second conductive type in a prescribed upper portion of the substrate. Thereafter, a source electrode and a drain electrode are formed to be electrically connected to the source region and the drain region, respectively.

CONSTITUTION: If any SCP(Service Control Point) senses overload state, the SCP transmits call gapping operation to an SSP(Service Switching Point) by using a call gapping message to reduce the frequency of the accessed service request(S10,S12). The SSP judges whether an SCP group having an intelligent network service requested by a service user exists(S14). If exists, the SSP judges whether the SCP having the intelligent network service requested by the service user exists within the corresponding SCP group(S16). If exists, it is judged whether the corresponding SCP requests the call gapping operation(S18). If not requested, the intelligent network service is requested to the corresponding SCP(S20). If requested, it is judged whether the corresponding call satisfies call gapping condition(S22). If not satisfies, the corresponding call is normally processed for requesting the intelligent service to the corresponding SCP(S20). If satisfies, the call gapping is adapted to the SCP sending the corresponding call gapping operation, so that the intelligent service is not requested to the corresponding SCP(S24).
