A method of forming a FINFET device includes providing a substrate with a plurality of trench devices arranged in array therein, each of the trench devices comprising a plug protruding above the substrate; forming a plurality of isolation structures along a first direction in the substrate adjacent to the trench devices so as to define an active area exposing the substrate; forming a spacer on each of the plug to define a reactive area between the active area and the spacer; and removing the isolation structures on the reactive area to form a fin structure in the active area.
