Low resistance anodized Ta/TaN line TFT-LCD

A low-resistance address and Cs lines were realized using a double-layer structure of alpha -Ta on TaN film, which had one-seventh of the conventional Ta resistivity. Point defects in TFT-LCDs (thin-film transistor liquid crystal displays), due to short circuits between pixel electrode and the Cs line, were decreased by a small leak current and pinhole-free anodic oxide film on Ta/TaN/sub x/. As a result, the PCVD (plasma chemical vapor deposition) machine running time can be increased, because TFT arrays become more dust tolerant.<
