摘要： Disclosed is a process for producing light olefins from hydrocarbon feedstock. The process is characterized in that a porous molecular sieve catalyst consisting of a product obtained by evaporating water from a raw material mixture comprising a molecular sieve with a framework of Si—OH—Al— groups, a water-insoluble metal salt, and a phosphate compound, is used to produce light olefins, particularly ethylene and propylene, from hydrocarbon, while maintaining excellent selectivity to light olefins. According to the process, by the use of a specific catalyst with hydrothermal stability, light olefins can be selectively produced in high yield with high selectivity from hydrocarbon feedstock, particularly full-range naphtha. In particular, the process can maintain higher cracking activity than the reaction temperature required in the prior thermal cracking process for the production of light olefins, and thus, can produce light olefins with high selectivity and conversion from hydrocarbon feedstock.

摘要： An optical transceiver for transmitting light source control information, which is applied to a Subcarrier Multiplexing optical network, is disclosed. The optical transceiver includes a controller, an SCM frame generation/restoring unit, a modulator/demodulator, and an EO/OE converter. The controller controls transmission of light source control information or collects received light source control information. The SCM frame generation/restoring unit generates an SCM frame containing light source control information received from the controller. The modulator/demodulator modulates an SCM frame generated by the SCM frame generation/restoring unit into a signal suitable for transmission. The EO/OE converter converts a transmission signal modulated by the modulator/demodulator into an optical signal and transmits the optical signal through an optical fiber. An optical network having a telephone office OLT and subscriber ONTs, each having the optical transceiver, is also disclosed.

摘要： In an exemplary embodiment, a fin active region is protruded along one direction from a bulk silicon substrate on which a shallow trench insulator is entirely formed so as to cover the fin active region. The shallow trench insulator is removed to selectively expose an upper part and sidewall of the fin active region, along a line shape that at least one time crosses with the fin active region, thus forming a trench. The fin active region is exposed by the trench and thereon a gate insulation layer is formed. Thereby, productivity is increased and performance of the device is improved. A fin FET employs a bulk silicon substrate of which a manufacturing cost is lower than that of a conventional SOI type silicon substrate. Also, a floating body effect can be prevented, or is substantially reduced.

摘要： A MOS transistor includes a gate structure extending forrom a semiconductor substrate in a vertical direction is disclosed. The gate structure includes a gate electrode extending from the substrate in a vertical direction, and a gate insulation layer enclosing the gate electrode. A channel pattern encloses the gate insulation layer, and a first conductive pattern extends from a lower portion of the channel pattern in a first direction verticalperpendicular to the channel pattern and in parallel with the substrate. A second conductive pattern extends from an upper portion of the channel pattern in a second direction verticalperpendicular to the channel pattern and in parallel with the substrate. Accordingly, the channel length of the MOS transistor is determined by a distance between the first and second conductive patterns, and a channel width of the MOS transistor is determined by a diameter of the gate structure. Short channel and narrow width effects are sufficiently prevented in a MOS transistor.
