Abstract:
A method of manufacturing a semiconductor device includes: forming a first mandrel and a second mandrel over a mask layer; depositing a spacer layer over the first mandrel and the second mandrel; forming a line-end cut pattern over the spacer layer between the first mandrel and the second mandrel; depositing a protection layer over the line-end cut pattern; etching the protection layer on the line-end cut pattern; reducing a width of the line-end cut pattern; etching first horizontal portions of the spacer layer with the reduced line-end cut pattern as an etching mask; removing the first mandrel and the second mandrel; and patterning the mask layer using the etched spacer layer and the etched line-end cut pattern as an etch mask.

Claim (Index 15):
The method of  claim 11 , wherein the line-end cut pattern masks a bottom portion of the spacer layer in the first opening from being etched while the spacer layer is patterned.
