Abstract:
Methods of fabricating a semiconductor integrated circuit having thin film transistors using an SEG technique are provided. The methods include forming an inter-layer insulating layer on a single-crystalline semiconductor substrate. A single-crystalline semiconductor plug extends through the inter-layer insulating layer, and a single-crystalline epitaxial semiconductor pattern is in contact with the single-crystalline semiconductor plug on the inter-layer insulating layer. The single-crystalline epitaxial semiconductor pattern is at least partially planarized to form a semiconductor body layer on the inter-layer insulating layer, and the semiconductor body layer is patterned to form a semiconductor body. As a result, the semiconductor body includes at least a portion of the single-crystalline epitaxial semiconductor pattern. Thus, the semiconductor body has an excellent single-crystalline structure. Semiconductor integrated circuits fabricated using the methods are also provided.
Abstract:
A fuel cell including a absorbing member is provided to improve performance and reliability of the fuel cell. The fuel cell includes an electricity generation unit and a medium member. The electricity generation unit includes a fuel supply unit, and a membrane electrode assembly (MEA), absorbing member, and air supply unit. A fuel is supplied through the medium member, and air is supplied through the air supply unit. During oxidation/reduction reaction between a fuel and air, condensed moisture or water is produced inside fuel cell, and the condensed moisture can block path of air flow into the fuel cell. In order to solve this problem, absorbing member is disposed between the membrane electrode assembly and the air supply unit. The absorbing member effectively absorbs moisture and blocking of air flow path by the moisture is prevented.
Abstract:
A mobile communication apparatus having an antenna array and a mobile communication method performed in the mobile communication apparatus, wherein the mobile communication apparatus includes a base station and mobile station, each having an antenna array. The mobile station measures the downlink characteristics of a channel for each antenna from a signal received from a base station, determines long-term information in which the correlation property of the channel for each antenna has been reflected from the measured downlink characteristics, transforms the long-term information into a feedback signal, and transmits the feedback signal to the base station. The base station receives the feedback signal, restores the long-term information from the received feedback signal, performs basis mapping and basis transformation on a dedicated physical channel signal using the restored long-term information, adds the basis-mapped and basis-transformed signal to each of pilot channel signals, and transmits the addition results to the mobile station.
