Abstract:
Structures and formation methods of a semiconductor device structure are provided. The method includes forming a first fin structure and a second fin structure over a semiconductor substrate, and forming a mask layer covering the first fin structure and the second fin structure. The method also includes performing a first etching operation using the second fin structure as an etch stop layer to partially remove the mask layer such that the etch stop layer protrudes from the mask layer after the first etching operation. The method further includes partially removing the second fin structure using a second etching operation after the first etching operation.

Claim (Index 9):
The method for forming a semiconductor device structure as claimed in  claim 8 , wherein a first etching rate of the first etching operation to the mask layer is higher than a second etching rate of the first etching operation to the second fin structure.
