Abstract: PURPOSE: A method for simultaneously transmitting voice signals and for recording telephone conversations of a mobile communication terminal is provided to control a path of external voice signals and a path of user voice signals, respectively, so as to simultaneously transmit the voice signals and to record the telephone conversations. CONSTITUTION: A controller checks whether a voice recorder is connected to external speaker terminals. If not, the controller intercepts a first muting circuit and a second muting circuit, and outputs an announcement message to suspend a recording operation. If the voice recorder is connected, the controller outputs a recording-standby confirming signal to the voice recorder, and checks whether a normal response signal is inputted. If not, the controller outputs a corresponding announcement message to suspend the recording operation. If the normal response signal is inputted, the controller inquires of a user whether the user performs the recording operation. If key input data of a user does not perform the recording operation, the controller intercepts the first/the second muting circuits to output a corresponding announcement message, and suspends the recording operation. If the key input data performs the recording operation, the controller controls the first/the second muting circuits to pass synthesized voice signals output from a transmission synthesizer. The controller checks whether an error is generated while passing the voice signals. If not, the controller continues the step of checking whether the error is generated. If the error is generated, the controller outputs a corresponding announcement message, and suspends the recording operation.

Thus, an anti-reflective layer pattern(42a) and a photoresist layer pattern(44a) are formed only on the active region of the substrate(40), exposing the field region. Particularly, the anti-reflective layer prevents the photoresist pattern(44a) from being damaged during the patterning process of the photoresist layer. The exposed region of the substrate(40) is then etched to form a trench(46) with a predetermined depth in the field region. Thereafter, the patterns(42a,44a) are simultaneously removed, and necessary insulation layers are formed in sequence on the resultant structure.
