Description

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.
