Jh. Choi et al., A NOVEL THIN-FILM-TRANSISTOR USING DOUBLE AMORPHOUS-SILICON ACTIVE LAYER, I.E.E.E. transactions on electron devices, 45(9), 1998, pp. 2074-2076
We have fabricated a novel low off-state leakage current thin-film tra
nsistor (TFT) using a chlorine incorporated amorphous silicon [a-Si:H(
: CI)] and amorphous silicon (a-Si:H) stacked active layer, in which c
onduction channel is formed in a-Si:H and a-Si:H(:Cl) is photo-insensi
tive material. The off-state photo-leakage current of the a-Si:H(: Cl)
/a-Si:H TFT is much lower than that a conventional a-Si:H TFT.
