Abstract: The present invention provides a method of forming a trench in a semiconductor substrate. First, a first patterned mask layer is formed on a semiconductor substrate. The first patterned mask layer has a first trench. Then, a material layer is formed along the first trench. Then, a second patterned mask layer is formed on the material layer to completely fill the first trench. A part of the material layer is removed when the portion of the material layer between the second patterned mask layer and the semiconductor substrate is maintained so as to form a second trench. Lastly, an etching process is performed by using the first patterned mask layer and the second patterned mask layer as a mask.

Abstract: A FET with a fin structure includes a substrate, an isolation structure and a gate structure. The substrate includes at least one fin structure. The fin structure includes two source/drain regions and a gate channel region between the two source/drain regions. The isolation structure is disposed on the substrate and surrounds the fin structure to expose an upper portion of the fin structure. A width of the gate channel region of the exposed upper portion of the fin structure is less than each of widths of the source region and the drain region. A gate structure covering two sidewalls of the gate channel region of the exposed upper portion of the fin structure is formed. Two sidewalls of the gate structure contact two facing sidewalls of the two source/drain regions, respectively.
