Abstract:
A substrate having a silicon region and a silicon germanium region is provided. A first set of fins in the silicon region and a second set of fins in the silicon germanium region is etched into the substrate. A set of protective caps on upper portions of the first and second sets of fins. A lower portion of each of the first and second sets of fins is oxidized. The silicon germanium portion of the lower portion of fin in the second set of fins is completely oxidized. The lower portion of the first set of fins is partially oxidized. A punchthrough stop isolation region is formed in the lower portion of the first set of fins.

Claim (Index 1):
A method for fabricating a FinFET device comprising:\n providing a substrate having a first set of fins in a silicon nFET region and a second set of fins in a silicon germanium pFET region; oxidizing a lower portion of each of the first and second sets of fins, wherein a silicon germanium portion of the lower portion of a fin in the second set of fins is completely oxidized and the lower portion of a fin in the first set of fins is partially oxidized; and after oxidizing the lower portion of each of the first and second sets of fins, forming a doped dielectric layer containing a p-type dopant over the first and second set of fins; and annealing the first and second set of fins, driving the p-type dopant into a silicon containing portion of the first and second set of fins forming doped regions in the lower portion of the first and second set of fins, the doped region is a punchthrough stop isolation region in the lower portion of the first set of fins, the doped region in the lower portion of the second set of fins is separated from the upper portion by the completely oxidized portion.
