Abstract: Method and apparatus for etching a thin layer including silicon nitride formed on a substrate are disclosed. Etchant including phosphoric acid and water is supplied on the substrate so that a liquid layer is formed on the substrate. The thin layer is etched by reaction between the thin layer and the etchant. Thickness of the liquid layer is measured to detect variation in the thickness of the liquid layer while etching the thin layer. Variation in the concentration of the phosphoric acid and the water is calculated based on the variation in the thickness of the liquid layer. Water is supplied on the substrate based on the variation in the concentration of the phosphoric acid and the water so that the concentration of the phosphoric acid and the water becomes a predetermined value.

Abstract: This invention relates to the method of doing a broadcast service of a short message in a communication system. According to the present invention, a transmission request message of a broadcast message including the name and telephone number of an information provider is received from the information provider through a message center. The transmission request message of the broadcast message processed in the message center is transmitted from the message center to a base station and therefrom to all terminals. The terminals receive the broadcast message including the information provider's name and telephone number and displays them on the display devices of the terminals. When the terminal user wants to communicate with the information provider, the terminal performs the process for communication between the information provider and the user by using the received information provider's telephone number.
