Description

A technique to improve and accelerate aluminum induced crystallization (AIC) by using hydrogen plasma is proposed. Raman spectroscopy and secondary ion mass spectrometry of crystallized poly-Si thin films show that hydrogen plasma radicals reduce the crystallization time of AIC. This technique shortens the annealing time from 10 to 4 h and increases the Hall mobility from 22.1 to 42.5 cm2/(V·s). The possible mechanism of AIC assisted by hydrogen radicals is also discussed.
