Thin film transistors (TFT's) were fabricated from poly-Si crystallize
d by a two-step annealing process on glass substrates. The combination
of low-temperature furnace annealing and high-temperature rapid therm
al annealing leads to a significant improvement in the material qualit
y. The TFT's measured with this two-step annealing material exhibit be
tter characteristics than those obtained by using conventional furnace
annealing.
