Abstract:
Embodiments of the invention include a semiconductor structure and a method of making such a structure. In one embodiment, the semiconductor structure comprises a first fin and a second fin formed over a substrate. The first fin may comprise a first semiconductor material and the second fin may comprise a second semiconductor material. In an embodiment, a first cage structure is formed adjacent to the first fin, and a second cage structure is formed adjacent to the second fin. Additionally, embodiments may include a first gate electrode formed over the first fin, where the first cage structure directly contacts the first gate electrode, and a second gate electrode formed over the second fin, where the second cage structure directly contacts the second gate electrode.

Claim (Index 14):
A method of forming a semiconductor structure, comprising:\n forming a cap layer over a substrate formed with a first semiconductor material, wherein the cap layer is etch selective to the first semiconductor material; forming a first and a second fin in the substrate; forming a shallow trench isolation (STI) layer over the substrate and around the first and second fins; removing the second fin to form an opening in the STI layer; epitaxially growing a second semiconductor material in the opening to form a replacement fin; recessing the STI layer; forming spacers adjacent to the sidewalls of each of the first fin and the replacement fin; forming cage structures adjacent to the spacers; removing the spacers to form an opening between at least one cage structure and the first fin and to form an opening between at least one cage structure and the replacement fin; forming a first gate electrode over the first fin; and forming a second gate electrode over the replacement fin.
