| Zusammenfassung: | The present disclosure relates to semiconductor structures and, more particularly, to airgaps which isolate metal lines and methods of manufacture. The structure includes: a plurality of metal lines formed on an insulator layer; and a dielectric material completely filling a space having a first dimension between metal lines of the plurality of metal lines and providing a uniform airgap with a space having a second dimension between metal lines of the plurality of metal lines. The first dimension is larger than the second dimension. |
