A method of manufacturing a semiconductor device may include forming a sacrificial layer on a substrate including a first region and a second region, forming a first pattern on the sacrificial layer of the second region, forming a second pattern on the sacrificial layer of the first region, forming first upper spacers on opposite sidewalls of the second pattern, removing the second pattern, etching the first sacrificial layer of the first region using the first upper spacers as an etch mask to form a third pattern, etching the first sacrificial layer of the second region using the first pattern as an etch mask to form a fourth pattern, forming first lower spacers at either side of the third pattern, forming second spacers on opposite sidewalls of the fourth pattern, removing the third pattern and the fourth pattern, and etching the substrate using the first lower spacers and the second spacers as etch masks.

Method of manufacturing semiconductor device using multiple patterning techniques

An edge detector includes a differential signal generator, a sense amplifier and a latch. The differential signal generator delays an input signal to generate a first differential signal and inverts the input signal to generate a second differential signal. The sense amplifier amplifies a difference between the first differential signal and the second differential signal to generate a first amplification signal and a second amplification signal at a first edge of a test clock signal and resets the first amplification signal and the second amplification signal at a second edge of the test clock signal. The latch generates an edge signal corresponding to edge information of the input signal in response to the first amplification signal and the second amplification signal.

Edge detectors and systems of analyzing signal characteristics including the same

A method for displaying menu items and a terminal for implementing the same are disclosed to improve user convenience. The terminal includes: a display unit; a controller for displaying arbitrary menu items on the display unit such that menu items at a particular position are differentiated from menu items at a different position, and a user input unit for selectively rearranging the position of the menu items by a user.

Terminal and menu display method thereof

A method for fabricating a semiconductor device is provided, which includes forming a first mask pattern and a second mask pattern on a first layer, forming a block mask that covers the second mask pattern on the first layer, forming first spacers on side walls of the first mask pattern, exposing the second mask pattern through removal of the first mask pattern and the block mask, forming a third mask pattern and a fourth mask pattern through etching of the first layer using the first spacers and the second mask pattern as etch masks, and forming second spacers and third spacers on side walls of the third mask pattern and side walls of the fourth mask pattern, respectively.

Method for fabricating semiconductor device

A display system comprising a user terminal apparatus configured to transmit a swimming image to a display apparatus, the display apparatus configured to reproduce the swimming image received from the user terminal apparatus, and a sensing apparatus configured to sense, while the user is swimming, user location information in real time, and transmit the sensed user location information to the user terminal apparatus or the display apparatus. The user terminal apparatus or the display apparatus displays swimming information of the user based on the received user location information.

Swimming race system, swimming race method, method of managing water quality, and display apparatus

An exemplary method of fabricating a semiconductor device is provided. First and second hard mask patterns adjacent to each other are formed on a substrate. First and second active fins are formed by etching the substrate using the first and second hard mask patterns as a etch mask. An isolation layer is formed to fill a region defined by the first and second active fins and the first and second hard mask patterns. A mask pattern is formed to be positioned on the first hard mask pattern and overlap the first active fin. A first trench is formed by etching a portion of the isolation layer and a portion of the second active fin using the mask pattern as an etch mask. The remaining portion of the second active fin is removed by performing an isotropic etching process.

A mobile terminal including a display having a menu display portion configured to display a menu group among a plurality of menu groups that are arranged in a same planar surface, a handler mechanism configured to traverse through the plurality of menu groups, and a controller configured to select one menu group among the plurality of menu groups to be displayed in the menu display portion based on a manipulation of the handler mechanism.
