Abstract: PURPOSE: An apparatus and a method for checking I/O(Input/Output) ports are provided to rapidly check whether an output port among output ports connected/disconnected to/from an operator terminal is operated normally or abnormally in an initiating or operating mobile communication exchange system according to user's request. CONSTITUTION: In the system with a plurality of I/O ports including Tx and Rx pins, an input/output unit inputs a command for detecting the abnormal operation of the plural I/O ports. A loop back unit is connected to the I/O ports to loop back a character of a predetermined size fed into the Tx pin of the I/O ports via the Rx pin of the I/O ports according to the command from the input/output unit. An I/O checking unit (a) generates a character of a predetermined size according to the command from the input/output unit to the Tx pin of the I/O ports; (b) receives the character of the predetermined size looped back to the Rx pin of the I/O ports; and (c) compares the received character with the initial input character to determine whether the corresponding I/O port is operated normally when the received character is identical to the initially input character or is operated abnormally when the received character is not identical to the initially input character or the character is not received for a predetermined time.

Abstract: PURPOSE: A method for forming a trench isolation is provided to prevent a dent in a nitride liner. CONSTITUTION: In the method, a pad oxide layer(101) is formed on a semiconductor substrate(100), and then a pad nitride layer and an anti-reflective coating layer are sequentially formed thereon. After a photoresist etching mask is formed, the layers lying thereunder and the substrate(100) are dry-etched to form a trench therein. Thereafter, a thermal oxide layer(105) is formed on inner surfaces of the trench to remove silicon lattice defects. After that, the nitride liner(106) is formed on entire surfaces in the trench and on the substrate(100) to relieve stress applied to the inner surfaces of the trench during subsequent processes. Then, a trench isolation layer such as an undoped silicate glass(USG) layer is deposited on the nitride liner(106) enough to fill the trench, and heat-treated under oxygen atmosphere at a temperature of 850 to 1050 deg. C for one to three hours. Next, the trench isolation layer and the anti-reflective layer are planarized, and then the pad nitride layer is removed.

Abstract: PURPOSE: A method for displaying a battery remainder life of a communication terminal is provided to calculate a slope of a battery discharge curved line and to estimate the battery remainder life to display the battery remainder life on a displayer, so as to estimate a present battery state and a cut off time by using a slope difference. CONSTITUTION: A controller confirms whether a battery is mounted(211). If so, the controller stands by until a battery voltage is stabilized(213). The controller checks whether the battery voltage is changed(217). If so, the controller records a present time and a voltage(219). The controller measures the battery voltage again(221). If the battery voltage is changed again, the controller records a present time and a voltage(225). The controller calculates the recorded time and the voltage in the step '219' and the recorded time and the voltage in the step '225', and calculates a slope of a battery discharge curved line. The controller checks whether the slope is within a set range(227). If so, the controller estimates a remaining time of a battery from the slope, and displays the remaining time on a displayer(229). If the slope is out of the set range, the controller displays that a battery remainder life gets shorter on the displayer, and completes the process(231).
