Abstract: PURPOSE: A self-aligned trench isolation method is provided to prevent a stringer from being formed between adjacent floating gates and reduce a time interval of fabricating a semiconductor device by etching a tunnel oxide layer and a gate oxide layer before a trench region is formed while using an oxide layer etch recipe that has low etch selectivity with respect to a semiconductor substrate and generates a small quantity of polymer. CONSTITUTION: A semiconductor substrate(51) has a cell array region(A) and a peripheral circuit region(B). A tunnel oxide layer(55) and a gate oxide layer(53) are formed on the semiconductor substrate in the cell array region and the peripheral circuit region. A cell trench mask pattern and a peripheral circuit trench mask pattern are respectively formed on the tunnel oxide layer and the gate oxide layer, including the first lower conductive layer pattern in contact with the tunnel oxide layer and the second lower conductive layer pattern in contact with the gate oxide layer. Trench regions(63) are formed by an in-situ process for consecutively etching the tunnel oxide layer, the gate oxide layer and the semiconductor substrate by using the cell trench mask pattern and the peripheral circuit trench mask pattern as etch masks. The profile of the sidewalls of the first and second lower gate conductive layer patterns is changed to have a profile with a negative slant.

Abstract: PURPOSE: A method for operating an application program of a mobile communication terminal is provided to enable a receiving mobile communication terminal to automatically operate an application program for processing data supplied from a service server, so that the service server can transmit the data such as advertising data and message data to the mobile communication terminal. CONSTITUTION: A terminal receives a call setup request signal through a paging channel(100). If a user selects a data receiving key to approve a call setup(101), the terminal generates a traffic channel(102). The terminal receives an application program operating message through the traffic channel(103), and recognizes the kind of a service(104). A controller of the terminal decides whether an application program for processing service data exists(105). If so, the controller operates the application program(106). The controller confirms an IP address from service server connection information of the operating message to receive the service data(107). If the user selects an end key to complete a service server connection(109), the controller cancels the service connection(110).
