A novel conformal shell doping profile (SDP) junctionless (JL) fin thin film transistor (FinTFT) formed by a damage-free molecular monolayer doping (MLD) method and a combination of microwave annealing (MWA) and CO_2 laser spike annealing (COLSA) is proposed and studied. Thanks to microwave annealing, an ultra-shallow (sub 5nm) and steep (< 0.8 nm/dec) doping profile is obtained. Moreover, the nonmelting COLSA can avoid dopant diffusion. As a result, we combine MWA and COLSA to enhance dopant activation and recover defect in our research. Finally, by the hybrid method, the JLFinTFT shows superior gate control (Ion/Ioff >10^7) for 3D stacked ICs applications in the future.
