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 11):
A method of forming an integrated circuit comprising:\n forming a trench in an insulation layer disposed on a semiconductor substrate, the trench having an aspect ratio of at least 2:1 at the largest width of the trench; forming a III-V semiconductor material in the trench and above a top surface of the insulation layer; planarizing the III-V semiconductor material that extends over the trench to a level generally coplanar with the top surface of the insulation layer; recessing the III-V semiconductor material in the trench so that the III-V semiconductor material has a top surface lower than the top surface of the insulation layer; forming a group IV semiconductor material on the III-V semiconductor material in the trench and extending above the top surface of the insulation layer; planarizing the portion of a group IV semiconductor material that extends over the trench to a level generally coplanar with the top surface of the shallow trench insulation; recessing the shallow trench insulation so that the group IV semiconductor has a top and sidewalls extending above the recessed top surface of the insulation layer to form an active fin portion; and thinning the sidewalls of the active fin portion to create a thinned active fin portion.
