    • A method of fabricating a MOSFET provides a plurality of nanowire-shaped channels in a self-aligned manner. According to the method, a first material layer and a semiconductor layer are sequentially formed on a semiconductor substrate. A first mask layer pattern is formed on the semiconductor layer, and recess regions are formed using the first mask layer pattern as an etch mask. A first reduced mask layer pattern is formed, and a filling material layer is formed on the surface of the substrate. A pair of second mask layer patterns are formed, and a first opening is formed. Then, the filling material layer is etched to form a second opening, the exposed first material layer is removed to expose the semiconductor layer, and a gate insulation layer and a gate electrode layer enclosing the exposed semiconductor layer are formed.
    • 制造MOSFET的方法以自对准方式提供多个纳米线状通道。 根据该方法,在半导体衬底上依次形成第一材料层和半导体层。 在半导体层上形成第一掩模层图案,并且使用第一掩模层图案作为蚀刻掩模形成凹陷区域。 形成第一缩小的掩模层图案,并且在基板的表面上形成填充材料层。 形成一对第二掩模层图案,形成第一开口。 然后,蚀刻填充材料层以形成第二开口,去除暴露的第一材料层以暴露半导体层,并且形成包围暴露的半导体层的栅极绝缘层和栅极电极层。
