Patent ID: 8734583

Claim:
A method for forming a transistor, comprising: forming a transistor body, including: forming a fin of amorphous semiconductor material on a substantially planar surface of a crystalline substrate, the fin formed on the surface having a cross-sectional thickness in at least one direction less than a minimum feature size, wherein the at least one direction is substantially parallel to the surface of the substrate; and performing a solid phase epitaxy (SPE) process to crystallize the amorphous semiconductor material using the crystalline substrate to seed the crystalline growth from the substrate in a direction away from the substrate to transform the fin of amorphous semiconductor material into a crystallized fin, the transistor body being formed in the crystallized fin between a first source/drain region and a second source/drain region; forming a surrounding gate insulator around the crystallized fin; and forming a surrounding gate around and separated from the crystallized fin by the surrounding gate insulator.
