Abstract:
Techniques for producing stacked SiGe nanowires using a condensation process without parasitic Ge nanowires as an undesired by-product. In one aspect, a method of forming SiGe nanowires includes the steps of: forming a stack of alternating Si and SiGe layers on a wafer; patterning fins in the stack; selectively thinning the SiGe layers in the fins such that the Si and SiGe layers give the fins an hourglass shape; burying the fins in an oxide material; and annealing the fins under conditions sufficient to diffuse Ge from the SiGe layers in the fins to the Si layers in the fins to form the SiGe nanowires. A FET device and method for formation thereof are also provided.

Claim (Index 1):
A field effect transistor (FET) device, comprising:\n at least one stack of silicon germanium (SiGe) nanowires; and a gate at least partially surrounding a portion of each of the SiGe nanowires that serves as a channel region of the FET device, wherein portions of the SiGe nanowires extending out from the gate serve as source and drain regions of the FET device, and wherein the SiGe nanowires have a uniform diameter throughout the source, drain, and channel regions of the FET device.
