20100240191 | METHOD OF FORMING SEMICONDUCTOR DEVICE HAVING A CAPACITOR - A method of forming a semiconductor device includes forming a lower electrode layer on a substrate, forming a surface oxide layer on the lower electrode layer, partially removing the lower electrode layer to form a lower electrode, removing the surface oxide layer to expose the lower electrode, forming a capacitor dielectric layer on the lower electrode, and forming an upper electrode on the capacitor dielectric layer. | 09-23-2010 |
20110222207 | Methods of forming a dielectric layer structure, and methods of manufacturing a capacitor using the same - In a method of forming a dielectric layer structure, a precursor thin film chemisorbed on a substrate in a process chamber is formed using a source gas including a metal precursor. The process chamber is purged and pumped out to remove a remaining source gas therein and to remove any metal precursor physisorbed on the precursor thin film. The forming of the precursor thin film and the purging and pumping out of the process chamber are alternately and repeatedly performed to form a multi-layer precursor thin film. An oxidant is provided onto the multilayer precursor thin film to form a bulk oxide layer. | 09-15-2011 |

20100265693 | TUBE-TYPE OR CHANNEL-TYPE LED LIGHTING APPARATUS - A light emitting diode (LED) lighting apparatus that may be used as interior lighting or advertisement lighting is disclosed. The LED lighting apparatus includes a channel-type or tube-type optical housing with a light emission surface and an LED array arranged in the optical housing. The light emission surface includes a valley line and a first inner ridge and a second inner ridge disposed on opposing sides of the valley line, and the LED array includes a plurality of LEDs whose centers are arranged along the valley line. | 10-21-2010 |
20100328961 | LIGHT-EMITTING MODULE - A light-emitting module includes a printed circuit board (PCB), a fastening member, and a light-emitting package. The PCB has a power-supplying pad to provide electrical power. The fastening member is disposed on the PCB and has a package-receiving hole exposing the power-supplying pad. The light-emitting package is received by the package-receiving hole such that the light-emitting package is electrically connected to the power-supplying pad and detachably coupled with the fastening member. Therefore, the light-emitting package may be easily combined with the PCB, and the light-emitting package may be replaced when desired. | 12-30-2010 |
20110235341 | METHOD OF MANUFACTURING A LIGHT EMITTING UNIT AND LIGHT EMITTING DEVICE MANUFACTURED USING THE METHOD - The present invention relates to a method of manufacturing a light emitting unit including mounting at least one light emitting element on a printed circuit board (PCB), connecting at least one terminal to the PCB, the at least one terminal to provide power to the at least one light emitting element, and molding a housing to enclose a light emitting part including the PCB and the at least one terminal. | 09-29-2011 |

20140133593 | METHOD AND APPARATUS FOR SUPPORTING MULTIPLE-ACCESS SIGNAL IN MOBILE COMMUNICATION SYSTEM - In order to generate multiple-access signals, each transmitter transmits information by using all or a part of channel resources. The signal of each transmitter is mapped to an OFDM time-frequency resource space as a trellis modulation path. A mobile communication system maps trellis modulation paths of a plurality of transmitters to the same resource space. In order to effectively detect and distinguish signals of a plurality of transmitters transmitted through the same channel resource space, a receiver uses a message passing method between symbols and a path connection method. The receiver uses a state space expansion method, a backward pre-decoding method, and a successive interference cancellation method to more efficiently reconstruct a discovery signal. | 05-15-2014 |
