A metal-insulator-metal (MIM) capacitor capable of achieving an enhancement in the reliability of a semiconductor device, and a method for manufacturing the same are disclosed. The disclosed MIM capacitor includes a metal-insulator-metal (MIM) capacitor which may include a first insulating film, a first metal layer formed over the first insulating film and a first capacitor insulating film formed over the first metal layer. A second metal layer may be formed over a portion of the first capacitor insulating film and second capacitor insulating film may be formed over the second metal layer. A third metal layer may be formed over a portion of the second capacitor insulating film and a nitride film may be formed over the third metal layer. A multilayer insulating film may be formed over the entire upper surface of the resulting structure. First and second metal lines may be formed in contact holes extending through the first capacitor insulating film, the second capacitor insulating film, and the nitride film after extending through the multilayer insulating film.

A signal transmission/reception apparatus of a communication system. The signal transmission apparatus receives an information vector, encodes the information vector into a structured Low Density Parity Check (LDPC) codeword using a structured LDPC coding scheme, and transmits the generated structured LDPC code to the signal reception apparatus. Then the signal reception apparatus receives a signal, and detects an information vector by decoding the received signal using a decoding scheme corresponding to the structured LDPC coding scheme used in the signal transmission apparatus.

A system and a method for receiving and processing broad-band signals in a software defined radio (SDR) terminal are provided. The system comprises first and second frequency pass units and an analog to digital signal converter (A/D converter). The first frequency pass unit converts an analog radio frequency (RF) signal into a direct current (DC) level signals and removes noise and DC components from the analog RF signal, if the RF signal is a high frequency signal. Otherwise, the second frequency pass unit removes noise and DC components from the analog RF signal, if the RF signal is a low frequency signal. The A/D converter converts the RF signal into a digital RF signal after the DC components are removed.

A method of forming a transistor reduces leakage current and hot carrier effects, and therefore improves current performance. The method of forming a transistor includes selectively etching the semiconductor substrate to form a substrate protrusion and expose a buried source/drain implant region. A gate insulating layer covers the substrate protrusion and the first source/drain region. A gate conductor layer is selectively etched to form a gate pattern covering the sidewalls of the substrate protrusion and a portion of the semiconductor substrate adjacent to the sidewalls of the substrate protrusion. A second source/drain region is stacked over the top of the substrate protrusion. Contacts connected to the gate pattern and the first and second source/drain regions.

A method and a Base Station (BS) of transmitting information for Random Access (RA) by a base station in a wireless communication system are provided. The BS generates RA information for beam alignment between the base station and each of a plurality of mobile terminals based on a number of reception beam forming patterns of the base station used for each of one or more RA channels and broadcasts the RA information to the plurality of mobile terminals. The RA information comprises information related to the number of reception beam forming patterns of the base station used for each of the one or more RA channels.
