| 20110249769 | METHOD AND APPARATUS OF COMPENSATION FOR AMPLITUDE AND PHASE DELAY USING SUB-BAND POLYPHASE FILTER BANK IN BROADBAND WIRELESS COMMUNICATION SYSTEM - Provided is a method and apparatus improving a deterioration of a gain flatness and a phase characteristic that may be incurred while a baseband signal is transformed into a immediate frequency (IF) signal and a radio frequency (RF) signal in a broadband wireless communication system. A sub-band extractor may divide the broadband signal into multiple sub-band signals, may pre-compensate for a gain and a phase delay of each sub-band signals in the baseband, and may combine the pre-compensated sub-band signals into the single broadband signal and thus, the deterioration of the gain flatness and a phase delay flatness that may be incurred while the broadband signal is transformed into the IF signal and the RF to signal, may be improved. | 10-13-2011 |

| 20080314864 | Method for manufacturing image sensor - Methods of forming a microlens for an image sensor are provided. In one embodiment, the microlens can be oxide film microlens fabricated by forming an oxide film on a substrate; forming a first photoresist pattern on the oxide film; performing a plasma processing with respect to the oxide film using the first photoresist pattern as a mask; removing the first photoresist pattern; and performing an isotropic etching of the plasma processed oxide film. In another embodiment, the oxide film microlens can be fabricated by forming an oxide film on a substrate; forming a first photoresist pattern on the oxide film; implanting ions into the oxide film using the first photoresist pattern as a mask; removing the first photoresist pattern; and performing an isotropic etching of the ion implanted oxide film. Convex shaped microlens can be provided as a result of the etching selectivity to the oxide film. | 12-25-2008 |
| 20090140252 | IMAGE SENSOR AND METHOD FOR MANUFACTURING THE SENSOR - An image sensor and a method of manufacturing the sensor. A method of manufacturing an image sensor may include at least one of: Forming a gate over a semiconductor substrate. Sequentially depositing a plurality of insulating films over the semiconductor substrate and the gate. Removing an upper-most insulating film of the plurality of insulating films by dry etching, thus forming a spacer at sides of the gate. Removing other insulating films by wet etching, while maintaining a bottom-most insulating film of the plurality of insulating films over the semiconductor substrate. Attacks may be prevented on a surface of a semiconductor substrate, making it possible to reduce generation of a dark signal, prevent plasma damage by controlling the thickness of a remaining oxide film with ease, and making it possible to improve yield and resolution of an image. | 06-04-2009 |
| 20090162987 | METHOD FOR FABRICATING MIM STRUCTURE CAPACITOR - A method for fabricating a metal/insulator/metal (MIM) structure capacitor includes forming a nitride film that is an insulating layer on a bottom electrode metal layer; forming titanium/titanium nitride (Ti/TiN) that is a top electrode metal layer on the nitride film; coating photo-resist on the top electrode metal layer and patterning a photo-resist layer; selectively etching the top metal electrode layer so that the nitride film remains using the patterned photo-resist layer as an etching mask and using the nitride film as an end point; and removing the remaining nitride film. | 06-25-2009 |
