    摘要: A method of forming a semiconductor structure includes providing a composite substrate, which includes a bulk silicon substrate and a silicon germanium (SiGe) layer over and adjoining the bulk silicon substrate. A first condensation is performed to the SiGe layer to form a condensed SiGe layer, so that the condensed SiGe layer has a substantially uniform germanium concentration. The condensed SiGe layer and a top portion of the bulk silicon substrate are etched to form a composite fin including a silicon fin and a condensed SiGe fin over the silicon fin. The method further includes oxidizing a portion of the silicon fin; and performing a second condensation to the condensed SiGe fin.

    摘要: A semiconductor structure includes a semiconductor substrate; a planar transistor on a first portion of the semiconductor substrate, wherein the first portion of the semiconductor substrate has a first top surface; and a multiple-gate transistor on a second portion of the semiconductor substrate. The second portion of the semiconductor substrate is recessed from the first top surface to form a fin of the multiple-gate transistor. The fin is electrically isolated from the semiconductor substrate by an insulator.
