Abstract: PURPOSE: A method of manufacturing a semiconductor device is provided to control uniformly the remaining thickness of a planarized pre-metal insulating layer by detecting an end point of a planarization using the difference of reflectivity between a nitride layer and an oxide layer. CONSTITUTION: A predetermined structure is formed within an active region of a silicon substrate. A pre-metal insulating layer is deposited thereon(S11). A nitride based insulating layer is deposited on the pre-metal insulating layer(S13). An oxide layer is deposited on the nitride based insulating layer(S14). The oxide layer is planarized until the nitride based insulating layer of an element dense region is detected(S15). At this time, the nitride based insulating layer is capable of being detected by using the difference of reflectivity between the oxide layer and the nitride based insulating layer. The nitride based layer of the element dense region and the oxide layer of an element sparse region are removed therefrom by performing a planarizing process for a pre-setting period(S16).

Abstract: PURPOSE: A method and apparatus for providing a call service are provided to increase an advertisement effect by discriminating a voice call service by stages and providing a successive advertisement corresponding to each stage. CONSTITUTION: Origination and destination terminals(100a,100b) provide a voice call service through a cable or wirelessly. A terminal information registering unit(500) provides state information of the origination and destination terminals(100a,100b) with reference to a supplementary service subscriber DB(600). A call service providing server(400) provides a call service to the origination and destination terminals(100a,100b). A call connection request signal including information on the origination and destination terminals(100a,100b) is received from a termination MSC(Mobile Switching Center)(200b) connected with the call service providing server(400). When the origination terminal(100a) is not a service-subscribed terminal, prior-call advertisement information corresponding to the destination terminal(100b) is extracted by using the information of the destination terminal(100b). The prior-call advertisement information, instead of a call connection tone, is transmitted to the origination terminal(100a). Transmission of the prior-call advertisement information is terminated according to a pre-set method.
