Inverse staggered polycrystalline silicon (poly-Si) and hydrogenated a
morphous silicon (a-Si:H) double structure thin-film transistors (TFT'
s) are fabricated based on the conventional a-Si:H TFT process on a si
ngle glass substrate, After depositing a thin (20 nm) a-Si:H using the
plasma CVD technique at 300 degrees C, Ar+ and XeCl (300 mJ/cm(2)) la
sers are irradiated successively, and then a thick a-Si:H (200 nm) and
n(+) Si layers are deposited again. The field effect mobilities of 10
and 0.5 cm (2)/V . s are obtained for the Laser annealed poly-Si and
the a-Si:H (without annealing) TFT's, respectively.
