Abstract: A method of forming a fin structure is provided. First, a substrate is provided, wherein a first region, a second region encompassing the first region, and a third region encompassing the second region are defined on the substrate. Then, a plurality of first trenches having a first depth are formed in the first region and the second region, wherein each two first trenches defines a first fin structure. The first fin structure in the second region is removed. Lastly, the first trenches are deepened to form a plurality of second trenches having a second depth, wherein each two second trenches define a second fin structure. The present invention further provides a structure of a non-planar transistor.
