Abstract:
Semiconductor structure and fabrication method are provided. The method includes: providing a substrate including device regions and isolation regions, adjacent with one another; providing discrete fins on the substrate, pitches between adjacent fins being substantially same; forming a protective layer on the sidewalls of the fins; removing a partial thickness of the fins in the isolation regions along with a partial thickness of the protective layer in the isolation regions by a first etching process; forming dummy fins by a second etching process to etch the remaining fins in the isolation regions using the remaining protective layers as a mask; removing the remaining protective layer after the second etching process; and forming isolation structures in the isolation regions on the substrate. The isolation structures have a top lower than the fins in the device regions and higher than the dummy fins in the isolation regions.

Claim (Index 3):
The fabrication method according to  claim 1 , wherein:\n the protective layer is formed by an atomic layer deposition method, and the protective layer is further formed on the substrate and on the top of the fins in addition to being formed on the sidewalls of the fins.
