Claim Text:
1. A manufacturing method for forming a semiconductor structure, comprising the following steps: providing a substrate, a hard mask being disposed on the substrate; patterning the hard mask to form a plurality of fin hard masks; performing a pattern transferring process, to transfer the patterns of the fin hard masks into the substrate, so as to form a plurality of fin structures on the substrate and arranged along a first direction; after the fin structures are formed, performing a first fin cut process, so as to define a first fin cut region, wherein the first fin cut process comprises forming a hard mask within the first fin cut region, and performing an etching process so as to remove the fin structures completely which are disposed outside of the first fin cut region; and performing a second fin cut process, so as to define a second fin cut region, wherein the second fin cut process comprises performing a second fin cut process, so as to remove the fin structures completely which are disposed within the second fin cut region, and, the second fin cut region is disposed along at least one edge of the first fin cut region, and the first fin cut region and the second fin cut region are arranged along the first direction.
