Abstract:
An electrophoretic display device has a first substrate that defines a plurality of sub-pixel areas; with shaped pixel electrodes formed in the sub-pixel areas. A second substrate is attached in facing relation to the first substrate during mass production. The second substrate has color filters of different colors (e.g., R, G, B). The areas of the color filters are less than the areas of their corresponding sub-pixel electrodes so as to thereby avoid or reduce a color mixture effect that may arise from mass production misalignment between the first and second substrates. In one class of embodiments, area consumed by the color filters is less than about 75% but more than about 45% of area consumed by respective pixel areas. Each pixel area comprises a white (W) sub-pixel area in addition to the differently colored sub-pixel areas (e.g., R, G, B).

Abstract:
Semiconductor integrated circuit devices having single crystalline thin film transistors and methods of fabricating the same are provided. The semiconductor integrated circuit devices include an interlayer insulating layer formed on a semiconductor substrate and a single crystalline semiconductor plug penetrating the interlayer insulating layer. A single crystalline semiconductor body pattern is provided on the interlayer insulating layer. The single crystalline semiconductor body pattern has an elevated region and contacts the single crystalline semiconductor plug.

A capping layer is formed to cover the sacrificial layer pattern and the interlayer insulating layer, and the capping layer is patterned to form an opening which exposes a portion of the sacrificial layer pattern. Subsequently, the sacrificial layer pattern is selectively removed to form a cavity in the capping layer, and a planarized single crystalline semiconductor body pattern is formed to fill the cavity and the opening.
Abstract:
Methods of forming a single crystal semiconductor thin film on an insulator and semiconductor devices fabricated thereby are provided. The methods include forming an interlayer insulating layer on a single crystal semiconductor layer. A single crystal semiconductor plug is formed to penetrate the interlayer insulating layer. A semiconductor oxide layer is formed within the single crystal semiconductor plug using an ion implantation technique and an annealing technique. As a result, the single crystal semiconductor plug is divided into a lower plug and an upper single crystal semiconductor plug with the semiconductor oxide layer being interposed therebetween. That is, the upper single crystal semiconductor plug is electrically insulated from the lower plug by the semiconductor oxide layer. A single crystal semiconductor pattern is formed to be in contact with the upper single crystal semiconductor plug and cover the interlayer insulating layer. The single crystal semiconductor pattern is grown by an epitaxy growth technique using the upper single crystal semiconductor plug as a seed layer, or by a solid epitaxy growth technique using the upper single crystal semiconductor plug as a seed layer.

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.
