We have studied the effect of H2 plasma treatment on the performance of a poly-Si thin-film
transistor (TFT) made by using metal-induced crystallization of amorphous silicon through a
cap layer (MICC). The p-channel poly-Si TFT made by using H2-plasma treatment of the MICC
poly-Si exhibited a field-effect mobility of 91.5 cm2/Vs, a threshold voltage of .2.1 V, and gate
voltage swing of 0.5 V/decade. The plasma treatment reduced the surface roughness from 16.7
°A
to 9.5 °A and the grain boundary traps significantly.
