Abstract
A semiconductor device and a method of forming the same, the semiconductor device includes fin shaped structures and a recessed insulating layer. The fin shaped structures are disposed on a substrate. The recessed insulating layer covers a bottom portion of each of the fin shaped structures to expose a top portion of each of the fin shaped structures. The recessed insulating layer has a curve surface and a wicking structure is defined between a peak and a bottom of the curve surface. The wicking structure is disposed between the fin shaped structures and has a height being about 1/12 to 1/10 of a height of the top portion of the fin shaped structures.
