| 20110167249 | COMPUTER SYSTEM AND METHOD CAPABLE OF REMOTELY RESTORING OPERATING SYSTEM - A computer system and a method for remotely restoring, upgrading, or booting an operating system (O.S). A communication unit communicates with an external device in which a restoring image of the operating system is stored. A user's input request for initialization, causes a controller to perform an initialization according to a power-on input, including checking whether or not a request for restoring the O.S. has been received from a user prior to starting a boot of the operating system. If a request for restoring the operating system is received, the restoring image stored in the external device is accessed through the communication unit to restore the operating system installed in the computer system. | 07-07-2011 |

| 20100173492 | METHOD OF FORMING SEMICONDUCTOR DEVICE PATTERNS - Provided is a method of forming patterns of a semiconductor device, whereby patterns having various widths can be simultaneously formed, and pattern density can be doubled by a double patterning process in a portion of the semiconductor device. In the method of forming patterns of a semiconductor device, a first mold mask pattern and a second mold mask patter having different widths are formed on a substrate. A pair of first spacers covering both sidewalls of the first mold mask pattern and a pair of second spacers covering both sidewalls of the second mold mask pattern are formed. The first mold mask pattern and the second mold mask pattern are removed, and a wide-width mask pattern covering the second spacer is formed. A lower layer is etched using the first spacers, the second spacers, and the wide-width mask pattern as an etch mask. | 07-08-2010 |
