Abstract: Aspects of the present invention generally relate to approaches for forming a semiconductor device such as a TSV device having a “buffer zone” or gap layer between the TSV and transistor(s). The gap layer is typically filled with a low stress thin film fill material that controls stresses and crack formation on the devices. Further, the gap layer ensures a certain spatial distance between TSVs and transistors to reduce the adverse effects of temperature excursion.

Abstract: Methods for fabricating integrated circuits are provided herein. In an embodiment, a method for fabricating an integrated circuit includes providing a mandrel layer overlying a semiconductor substrate and patterning the mandrel layer into mandrel structures. The method further includes forming a protective layer between the mandrel structures. Spacers are formed around each of the mandrel structures and overlying the protective layer to define exposed regions of the protective layer and covered regions of the protective layer. The exposed regions of the protective layer are etched using the spacers and the mandrel structures as a mask. The spacers are removed from the covered regions of the protective layer. The covered regions of the protective layer form mask segments for etching the semiconductor substrate. The method removes the mandrel structures and etches the semiconductor substrate exposed between mask segments to form semiconductor fin structures.
