Patent ID: 8080481

Claim:
A method for manufacturing a semiconductor nanowire device from a substrate, the method comprising the steps of: forming a first thermal oxide layer on a (100) single crystal silicon first substrate; doping impurities of high concentration into a doped region of the first substrate, the doped region comprising a first region, corresponding to a support structure, and a second region, corresponding to a nanowire, the nanowire extending lengthwise from the support structure; patterning the first thermal oxide layer to form the support structure for supporting the nanowire, the support structure being wider than the nanowire such that the support structure exhibits higher mechanical stress than the nanowire without breaking; dry etching the silicon first substrate; wet etching the silicon first substrate by using a silicon anisotropic etching solution; forming a second thermal oxide layer on the silicon first substrate; separating the nanowire from the single crystal silicon first substrate by removing the second thermal oxide layer; separating the nanowire from the support structure by breaking a portion of the doped region; and transferring the nanowire to a second substrate.
