    • Provided is a semiconductor optical device having a current-confined structure. The device includes a first semiconductor layer of a first conductivity type which is formed on a semiconductor substrate and includes one or more material layers, a second semiconductor layer which is formed on the first semiconductor layer and includes one or more material layers, and a third semiconductor layer of a second conductivity type which is formed on the second semiconductor layer and includes one or more material layers. One or more layers among the first semiconductor layer, the second semiconductor, and the third semiconductor layer have a mesa structure. A lateral portion of at least one of the material layers constituting the first semiconductor layer, the second semiconductor layer, and the third semiconductor layer is recessed, and the recess is partially or wholly filled with an oxide layer, a nitride layer or a combination of them. The semiconductor optical device having the current-confined region is mechanically reliable, highly thermally conductive, and commercially preferable and can be used in a wavelength range for optical communications.

    • A method of forming an isolation film in a semiconductor device is disclosed. The disclosed method includes performing a patterning process on a predetermined region of a semiconductor substrate in which a patterned pad film is formed, forming a trench defining an inactive region and an active region, forming a liner film on the entire surface including the trench, forming an insulating film for trench burial only within the trench, stripping the remaining liner film formed except for the inside of the trench and the patterned pad film formed below the liner film, forming a sacrificial film on the entire surface, and performing a polishing process on the entire surface in which the sacrificial film is formed until the semiconductor substrate of the active region is exposed, thereby forming the isolation film having no topology difference with the semiconductor substrate of the active region.

    • The present invention relates to a verb pattern automatic extension and verification apparatus for use in a Korean-Chinese machine translation system. The verb pattern automatic extension and verification apparatus automatically extracts the verb pattern source part that is not applied with the verb pattern contained in the current Korean and Chinese pattern dictionary, and automatically generates the new Korean-Chinese verb pattern based on Chinese target language. Meanwhile, the verb pattern automatic extension and verification apparatus according to the present invention automatically extends one newly generated Korean-Chinese verb pattern to a plurality of similar verb pattern candidates, and newly registers the newly-generated and extended Korean-Chinese verb patterns in the Korean and Chinese verb pattern dictionary database. Accordingly, it is possible to easily and automatically collect a large quantity of the Korean and Chinese verb patterns. Further, the translation rate of the Korean-Chinese machine translation system can be rapidly increased due to the automatically increasing verb patterns.
    • 本发明涉及一种用于韩国 - 中国机器翻译系统的动词模式自动扩展和验证装置。 动词模式自动扩展和验证装置自动提取不包含当前韩文和中文模式字典中的动词模式的动词模式源部分,并根据中文目标语言自动生成新韩语动词模式。 同时,根据本发明的动词模式自动扩展和验证装置将一个新生成的韩文 - 中文动词模式自动地扩展到多个类似的动词模式候选,并且将新生成的和扩展的韩文 - 中文动词模式新登录在 韩文和中文动词模式字典数据库。 因此,可以容易地且自动地收集大量的韩文和中文动词模式。 此外,由于动态模式的自动增加,韩文机翻译系统的翻译速度可以迅速提高。
