    Investigation of Amorphous IGZO TFT Employing Ti/Cu Source/Drain and SiNx Passivation

    We successfully fabricated a-IGZO TFTs employing a Ti/Cu source/drain (S/D) and SiNx passivation in order to reduce the line-resistance, as compared to most oxide TFTs that use Mo (or TCO) and SiO2 for their S/D ...

    Microstructural Evolution of Nickel Induced Crystallization of Amorphous Silicon

    The Ni silicide-mediated phase transformation of amorphous to crystalline silicon (c-Si) was studied using transmission electron microscopy. Amorphous silicon (a-Si) films coated with very thin Ni layer (∼10-1Å) ...

    The effect of active-layer thickness on the characteristic of nanocrystalline silicon thin film transistor

    We fabricated nc-Si TFTs in order to investigate the effect of the active-layer thickness on the characteristic of the nc-Si TFT. Bottom gate nc-Si TFTs were fabricated at 350°C using ICP-CVD. The thicknesses ...

    Epitaxial Sr-Bi-Ta Oxide Films of Cubic Fluorite-Like Structure

    Epitaxial Sr-Bi-Ta oxide films of a cubic fluorite-like structure were grown by pulsed laser deposition. As the laser fluence increased, the lattice constant decreased. It was revealed that the Ta ion concentr...
