    • 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.
    • 在一个示例性实施例中,翅片有源区域沿着整体形成浅沟槽绝缘体的体硅基板沿着一个方向突出,以覆盖翅片有源区域。 去除浅沟槽绝缘体,以沿着至少一次与翅片有源区交叉的线形状选择性地暴露翅片有源区的上部和侧壁,从而形成沟槽。 翅片有源区域被沟槽暴露,并且形成有栅极绝缘层。 从而,提高了生产效率并提高了设备​​的性能。 翅片FET采用其制造成本低于常规SOI型硅衬底的制造成本的体硅衬底。 此外,可以防止浮体效应或大大降低浮体效应。

    • In a semiconductor device, the semiconductor device may include a first active structure, a first gate insulation layer, a first gate electrode, a first impurity region, a second impurity region and a contact structure. The first active structure may include a first lower pattern in a first region of a substrate and a first upper pattern on the first lower pattern. The first gate insulation layer may be formed on a sidewall of the first upper pattern. The first gate electrode may be formed on the first gate insulation layer. The first impurity region may be formed in the first lower pattern. The second impurity region may be formed in the first upper pattern. The contact structure may surround an upper surface and an upper sidewall of the first upper pattern including the second impurity region. Accordingly, the contact resistance between the contact structure and the second impurity region may be decreased and structural stability of the contact structure may be improved.
