Abstract:
Semiconductor structures and fabrication methods thereof are provided. An exemplary fabrication process includes providing a semiconductor substrate having a first region and a second region and having a plurality of first fins in the first region and a plurality of second fins in the second region; performing a first oxidation process on the first fins to form a first oxide layer on surfaces of the first fins and to cause corners between top surfaces and side surface of the first fins to form first rounded corners; and performing a second oxidation process on the second fins to form a second oxide layer on surfaces of the second fins and to cause corners between top surfaces and side surface of the second fins to form second rounded corners. A radius of curvature of the first rounded corner is different from a radius of curvature of the second rounded corner.

Claim (Index 17):
The method according to  claim 16 , after forming the isolation structure and before forming the gate structure, further comprising:\n removing the first oxide layer and the second oxide layer exposed by the isolation structure.
