摘要:
An apparatus and method for notifying a communication network event in an application server capable of supporting open APIs based on Web services are disclosed. The event notification apparatus configures an event table using a service provisioning manager to perform event notification, and registers static events, allows a service application to request the beginning of dynamic event notification from a gateway. If a corresponding static or dynamic event occurs in the communication network, and the gateway calls an event notification API processor, the event notification API processor transmits the event to the service application by referring to the event table, such that it can notify the service application of the static or dynamic event under the open API environment based on Web services.

Disclosed herein is a method of manufacturing a semiconductor device. The method includes forming an etch-stop film on a semiconductor substrate in which a predetermined structure is formed, and then forming an interlayer insulating film. The method also includes etching a predetermined region of the interlayer insulating film, and then stopping the etch process at the etch-stop film, to form a damascene pattern. The method employs an etch-stop film made of a material having a low dielectric constant. Accordingly, an increase in the capacitance due to an etch-stop film formed of the existing material having a high dielectric constant can be prevented. It is therefore possible to prevent a reduction of RC delay and also to accelerate the operating speed of devices.
