Abstract: A semiconductor structure includes an isolation feature formed in the semiconductor substrate and a first fin-type active region. The first fin-type active region extends in a first direction. A dummy gate stack is disposed on an end region of the first fin-type active region. The dummy, gate stack may overlie an isolation structure. In an embodiment, any recess such as formed for a source/drain region in the first fin-type active region will be displaced from the isolation region by the distance the dummy gate stack overlaps the first fin-type active region.
