Abstract:
A self-aligned SiGe FinFET device features a relaxed channel region having a high germanium concentration. Instead of first introducing germanium into the channel and then attempting to relax the resulting strained film, a relaxed channel is formed initially to accept the germanium. In this way, a presence of germanium can be established without straining or damaging the lattice. Gate structures are patterned relative to intrinsic silicon fins, to ensure that the gates are properly aligned, prior to introducing germanium into the fin lattice structure. After aligning the gate structures, the silicon fins are segmented to elastically relax the silicon lattice. Then, germanium is introduced into the relaxed silicon lattice, to produce a SiGe channel that is substantially stress-free and also defect-free. Using the method described, concentration of germanium achieved in a structurally stable film can be increased to a level greater than 85%.

Claim (Index 17):
A device, comprising:\n a substrate; a plurality of first fins on the substrate and spaced apart from one another along a first direction, each of the plurality of first fins having respective source and drain regions aligned with one another along a second direction that is transverse to the first direction; a plurality of second fins on the substrate and spaced apart from one another along the first direction, the plurality of second fins being spaced apart from the plurality of first fins along the second direction, each of the plurality of second fins having respective source and drain regions aligned with one another along the second direction; and a plurality of source and drain extensions that extend along the second direction from respective sidewalls of each of the first fins and the second fins.
