Abstract:
The present disclosure relates to semiconductor structures and, more particularly, to a hybrid fin cut with improved fin profiles and methods of manufacture. The structure includes: a plurality of fin structures in a first region of a first density of fin structures; a plurality of fin structures in a second region of a second density of fin structures; and a plurality of fin structures in a third region of a third density of fin structures. The first density, second density and third density of fin structures are different densities of fin structures, and the plurality of fin structures in the first region, the second region and the third region have a substantially uniform profile.

Claim (Index 14):
A method comprising:\n forming a plurality of hardmask fin structures in a first region, a second region and a third region of a semiconductor chip; forming a first masking material over the plurality of hardmask fin structures in the first region, the second region and the third region; forming trenches in the first masking material to expose selected hardmask fin structures of the plurality of hardmask fin structures in the first region, the second region and the third region; forming a second masking material in the trenches to cover the exposed selected hardmask fin structures in the first region, the second region and the third region; partially removing the second masking material in the third region to expose adjacent hardmask fin structures of the selected hardmask fin structures in the third region; removing the exposed adjacent hardmask fin structures in the third region to form spaces; forming a third masking material in the spaces in the third region; removing the second masking material in the first region and the second region and remaining portions of the second masking material in the third region to expose the selected hardmask fin structures remaining in the first region, the second region and the third region; removing the selected hardmask fin structures which were remaining in the first region, the second region and the third region; removing the first masking material and forming fin structures in the first region, the second region and the third region corresponding to the locations which include the hardmask fin structures and the third masking material; and removing unwanted fin structures which are masked with the third material in the third region to create a region of less density compared to the first region and the second region.
