Abstract: Provided are a silicon nitride film etching composition, a method of etching a silicon nitride film using the same, and a manufacturing method of a semiconductor device. Specifically, a silicon nitride film may be highly selectively etched as compared with a silicon oxide film, and when the composition is applied to an etching process at a high temperature and a semiconductor manufacturing process, not only no precipitate occurs but also anomalous growth in which the thickness of the silicon oxide film is rather increased does not occur, thereby minimizing defects and reliability reduction.

Abstract: Provided are a silicon nitride film etching composition, a method of etching a silicon nitride film using the same, and a manufacturing method of a semiconductor device. Specifically, a silicon nitride film may be stably etched with a high selection ratio relative to a silicon oxide film, and when the composition is applied to an etching process at a high temperature and a semiconductor manufacturing process, not only no precipitate occurs but also anomalous growth in which the thickness of the silicon oxide film is rather increased does not occur, thereby minimizing defects and reliability reduction.

Abstract: An apparatus for displaying a thumbnail of a panoramic photo is provided. The apparatus includes a camera configured to capture a photo in a panorama photography mode, a controller configured to control a thumbnail image to be created by reducing the panoramic photo shot by the camera module by a predetermined first factor, and a display unit configured to display the thumbnail image on a screen. The controller controls the thumbnail image to be updated by further reducing the thumbnail image by a second factor to fit in a displayable screen range of the display unit if a width of the thumbnail image exceeds the displayable screen range as a shooting angle of the panoramic photo shot by the camera module increases, and controls the updated thumbnail image to be displayed on the screen.

Abstract: A method and apparatus for dial input using a voice in a mobile terminal are provided. The method includes recognizing a voice inputted from a microphone when a call is connected, identifying a numeral corresponding to the recognized voice, and transmitting the identified numeral to a phone number to which the call is connected.
