Abstract
We characterize poly-Si thin films doped by KrF excimer laser irradiation with a phosphoric-acid coating. In this method, implantation and dopant activation can be performed simultaneously without damage of the poly-Si crystallization. After the laser doping, the mobility, carrier concentration, activation ratio, and resistivity of poly-Si were 61 cm2/Vs, 1.5×1018 cm−3, 14.6 %, and 0.08 Ω.cm, respectively.
