Abstract:
A transistor having an ultra thin fin profile and its method of fabrication is described. The transistor comprises a semiconductor substrate having an insulation layer formed on a semiconductor substrate. A fin extends from the semiconductor substrate. The fin has a subfin portion on the semiconductor substrate and an active fin portion on the subfin portion. The subfin portion is disposed in a trench formed in the insulation layer. The subfin portion comprises a III-V semiconductor material and the active fin portion comprises a group IV semiconductor material.

Claim (Index 18):
A device comprising:\n a semiconductor substrate: an insulation layer disposed on the semiconductor substrate; a trench disposed in the insulation layer; a fin having an active fin portion disposed on a subfin portion, the subfin portion having a lower portion formed in a faceted notch in the substrate below the insulation layer and an upper portion disposed in the trench in the insulation layer wherein the width the upper portion of the subfin portion at the bottom of the trench is wider than the width of the upper portion of the subfin at the top of the insulation layer, wherein the subfin portion comprises a III-V semiconductor material and wherein the active fin portion comprises a semiconductor material different from the III-V semiconductor material of the subfin portion.
