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 15):
The method according to  claim 13 , further comprising:\n etching the first isolation layer and the second isolation layer to form an isolation structure to expose portions of side surfaces of the plurality of first fins and portions of side surfaces of the plurality of second fins.
