Abstract:
1. A method for tuning the drive strength of an electronic device, comprising: forming a source and a drain in a single-crystal material; forming a single-crystal first fin from said single-crystal material, said first fin having first and second opposing ends and first and second opposing sidewalls and extending along a first longitudinal axis from said first to said second end of said first fin, said first end of said first fin in contact with said source and said second end of said first fin in contact with said drain; aligning said first longitudinal axis to a crystal-plane of said single-crystal material; forming a single-crystal second fin from said single-crystal material, said second fin having first and second opposing ends and first and second opposing sidewalls and extending along a second longitudinal axis from said first to said second end of said second fin, said first end of said second fin in contact with said source and said second end of said second fin in contact with said drain; aligning said second longitudinal axis to a plane rotated away from said crystal plane; and forming a single conductive gate in contact with a gate dielectric formed on said first and second sidewalls of said first fin and on said first and second sidewalls of said second fin.
