Abstract: Provided is a method of fabricating a semiconductor device. The method of fabricating a semiconductor device comprises forming a first layer which has a first surface, does not comprise an acid, and comprises a metal material; forming, on the first layer, a second layer which comprises a trench exposing the first surface, has a second surface intersecting the first surface within the trench, and comprises an acid and an organic material; providing a first precursor comprising an alkoxy group and silicon; and forming a third layer comprising silicon oxide on the second surface within the trench. The third layer is in contact with a portion of the first surface within the trench.

Abstract: An apparatus for detecting the opening and closing of a slide-type mobile communication terminal having a main body and a sub-body mounted on the main body. The apparatus includes a signal generating element of bar-type provided in the sub-body for generating a predetermined signal; a first and a second signal sensor provided at two positions separated by a predetermined interval in the main body so as to face the signal generating element respectively when the sub-body is slid up and down relative to the main body, the first and second signal sensors detecting the predetermined signal; and a control unit for performing corresponding functions according to the opening and closing operations of the mobile communication terminal represented by different signals generated by the first and second signal sensors.

Abstract: A device and method for automatically controlling power of a radio mobile terminal connected to a hands-free kit and for preventing the radio mobile terminal from malfunctioning. In a power control method for automatically turning on a radio mobile terminal connected to a hands-free kit, the radio mobile terminal including a power control signal generator, a signal output terminal and a signal input terminal, the hands-free kit including a power-on signal generator and a signal detector, a power-on signal is supplied to the signal input terminal for a predetermined time period through the power-on signal generator when the radio mobile terminal is connected to the hands-free kit. After the predetermined time period elapses, generating the power-on signal is stopped. It is determined if the driving signal generated by the signal output terminal is detected through the signal detector. If the driving signal is detected, generating the power-on signal is stopped.

Abstract: A regulator system and method for controlling the level of an output voltage. The regulator system comprises a regulator, enabled in response to an enable signal, for converting a level of an input signal into a predetermined value and providing a first output signal, a smoother for smoothing the first output signal from the regulator and providing the smoothed signal as a second output signal, and an enable signal generator for generating an initial version of the enable signal to control an enable period of the regulator so that the second output signal has a target level and adjusting an enable active period of the initial version of the enable signal to generate a new version of the enable signal when a level of the second output signal associated with the initial version of the enable signal is different from the target level.
