Abstract: A method of manufacturing a semiconductor device includes: forming a trench in an insulating interlayer by etching the insulating interlayer; forming a conductive layer on bottom, side, and upper surfaces of the insulating interlayer where the trench is formed, using a first deposition process, the conductive layer on the bottom surface of the trench being thicker than the conductive layer on the side surface of the trench; forming a sacrificial layer in the trench covering the conductive layer formed on the bottom surface of the trench using a second deposition process different from the first deposition process; selectively removing the conductive layer formed on the upper surface of the insulating interlayer and formed on the side surface of the trench left exposed through the sacrificial layer; and selectively removing the sacrificial layer, to form a conductive line using the conductive layer remaining on the bottom surface of the trench.

Abstract: A microwave oven and a controlling method therefor employ a data receiving section connected to an external device which is connectable to the Internet to receive cooking data from the external device, and a driving section for performing the cooking operation by using the cooking data received from the Internet. The microwave oven also includes a memory for storing the cooking data received from the Internet. A user can select and cook his/her desired cooking menus from a wide range of cooking menus provided by the Internet, and can also adjust, replace and store the cooking data received from the Internet as he/she pleases.

Abstract: Disclosed is a wall-mounted type microwave oven including a main body having a suction grill for an air passageway to a cavity, a hood duct for a second air passageway for fumes and smoke generated from a gas range placed below the microwave oven, a hood inlet port and outlet port coupled to the hood duct, a hood fan installed within the hood duct of the main body, and discharging air drawn in through the suction port and the hood inlet port, through the hood outlet port, a louver opening and closing the suction grill, a louver driving motor driving the suction louver, a hood switch turning on over a predetermined temperature, and activating the hood fan, and a hood driving circuit part activating the louver driving motor so as to open the louver depending upon a turn-on state of the hood switch.

Abstract: A microwave detecting device outputs a first predetermined voltage in accordance with the presence/absence of microwave in a waveguide. A microcomputer inputs the first predetermined voltage, outputs a second predetermined voltage in accordance with the level of the first predetermined voltage, then detects the voltage of an input port of the first predetermined voltage by applying the second predetermined voltage to the input port of the first predetermined voltage, and displays the operational status of the microwave detecting section in accordance with the voltage detected from the input port. The microwave detecting section includes a diode sensor, which is connected between the waveguide and the input port of the microcomputer in a forward direction to output the first predetermined voltage in accordance with the presence/absence of the microwave in the waveguide.
