Zusammenfassung:A system and method for manufacturing multiple-gate semiconductor devices is disclosed. An embodiment comprises multiple fins, wherein intra-fin isolation regions extend into the substrate less than inter-fin isolation regions. Regions of the multiple fins not covered by the gate stack are removed and source/drain regions are formed from the substrate so as to avoid the formation of voids between the fins in the source/drain region.
