| 20110013092 | APPARATUS AND METHOD OF SWITCHING CHANNEL UNDER WIRELESS NETWORK CIRCUMSTANCES - An apparatus and method of switching a channel under wireless network circumstances is provided, which can secure network resources by performing channel switching and channel bonding with an adjacent network if the network resources of the currently participating network are insufficient in performing wireless data communications. The apparatus includes a message analysis unit analyzing at least one received channel information message and confirming whether a channel corresponding to the channel information message and a channel adjacent to the channel are usable, a channel switching unit performing a channel switching with a usable target channel among the channels with reference to whether the confirmed channel and the adjacent channels are usable, in accordance with a result of determining whether network resources of a currently used channel are insufficient, and a channel bonding unit performing a channel bonding between the channel-switched target channel and the adjacent channels. | 01-20-2011 |

| 20100328750 | HIGH-SPEED OPTICAL MODULATOR AND METHOD OF MODULATING LIGHT BY USING THE SAME - Provided are a high-speed optical modulator and a method of modulating light by using the same. The optical modulator includes first and second resonance cavities that are sequentially stacked on a transparent substrate, wherein the first and second resonance cavities each include an electric-optical layer. According to the method, first and second voltages having different sizes are simultaneously applied respectively to the first and second resonance cavities, and then for the other configuration of the modulator mutually interchanged voltages are applied. | 12-30-2010 |

| 20100295113 | SEMICONDUCTOR DEVICES COMPRISING A PLURALITY OF GATE STRUCTURES - Semiconductor devices including a plurality of gate structures disposed on a semiconductor substrate are provided. Each of the gate structures includes a tunnel dielectric layer, a floating gate, an inter-gate dielectric layer, a control gate, and a mask layer. Liners cover opposing sidewalls of adjacent floating gates. Spacers are disposed on the liners, the spacers protruding from opposing sidewalls of adjacent ones of the gate structures, and a top of each of the spacers is disposed below a top of a corresponding one of the gate structures. The liners define sidewalls of respective air gaps and the spacers define tops of the respective air gaps. | 11-25-2010 |
| 20110163367 | Semiconductor Devices Comprising a Plurality of Gate Structures - Semiconductor devices are provided. The semiconductor devices may include a plurality of gate structures disposed on a semiconductor substrate, each of the gate structures including a floating gate, an inter-gate dielectric layer, and a control gate. The semiconductor devices may also include liners on opposing sidewalls of adjacent ones of the gate structures. The liners may define a gap. A first width of the gap may be less than a second width of the gap. | 07-07-2011 |
