  • Abstract
    To improve device performance, laser annealing was applied to Ge n-MOSFETs, which gave a low sheet resistance of 68 Ω/sq, a small ideality factor of 1.3, and a large ~105 forwardreverse current in the source-drain n+/p junction. The laser-annealed gate-first TaN/La2O3/SiO2/Ge n-MOSFETs showed a high mobility of 603 cm2/Vs and a good mobility of 304 cm2/Vs at a 1.9-nm equivalent oxide thickness.
