    • A method of forming fins for fin-shaped field effect transistor (finFET) devices includes forming a plurality of sacrificial mandrels over a semiconductor substrate. The plurality of sacrificial mandrels are spaced apart from one another by a first distance along a first direction, and by a second distance along a second direction. Spacer layers are formed on sidewalls of the sacrificial mandrels such that portions of the spacer layers between sacrificial mandrels along the first direction are merged together. Portions of the spacer layers between sacrificial mandrels along the second direction remain spaced apart. The sacrificial mandrels are removed. A pattern corresponding to the spacer layers is transferred into the semiconductor layers to form a plurality of semiconductor fins. Adjacent pairs of fins are merged with one another at locations corresponding to the merged spacer layers.
    • 形成鳍状场效应晶体管(finFET)器件的鳍片的方法包括在半导体衬底上形成多个牺牲心轴。 多个牺牲心轴沿着第一方向彼此间隔开第一距离,并且沿第二方向间隔开第二距离。 间隔层形成在牺牲心轴的侧壁上,使得沿着第一方向的牺牲心轴之间的间隔层的部分被合并在一起。 沿着第二方向的牺牲心轴之间的间隔层的部分保持间隔开。 牺牲心轴被去除。 对应于间隔层的图案被转移到半导体层中以形成多个半导体鳍片。 相邻的翅片对在与合并的间隔层相对应的位置处彼此合并。
