摘要:
A fin field effect transistor and a manufacturing method thereof are provided to reduce off current and gate induced drain leakage by extending an effective distance between a source and a drain. An active pin(118) having a round trench(114) on an upper surface. A gate insulation film is formed on a surface of the active fin. A gate electrode(122) is formed in an inner surface of the trench, and has a line width narrower than an upper width of the trench. Impurity regions are formed under the surface of the active fin at both sides of the gate electrode. The trench extends to edges of both sides of the active fin in a first direction perpendicular to a longitudinal direction of the active fin.
