Claim Text:
1. A method for atom probe tomography (APT) sample preparation from a three-dimensional (3D) field effect transistor device formed within a semiconductor structure, the method comprising: identifying, based on a measured capacitance-voltage (C-V) characteristic, a defect associated with a Fin structure corresponding to the 3D field effect transistor device; detaching, using a nanomanipulator, the Fin structure from the 3D field effect transistor device based on the measured capacitance-voltage (C-V) characteristic identifying the defect associated with the 3D field effect transistor device; and welding the detached Fin having the identified defect to the nanomanipulator probe tip using an incident focused ion beam.
