Abstract
A methodology for forming a fin field effect transistor (FinFET) includes the co-integration of various isolation structures, including gate cut and shallow diffusion break isolation structures that are formed with common masking and etching steps. Following an additional patterning step to provide segmentation for source/drain conductive contacts, a single deposition step is used to form an isolation dielectric layer within each of gate cut openings, shallow diffusion break openings and cavities over shallow trench isolation between device active areas.
