In this paper, dc-stress-induced degradation in bridged-grain (BG) polycrystalline silicon (poly-Si) thin-film transistors (TFTs) is systemically characterized and investigated. Compared with normal poly-Si TFTs, BG poly-Si TFTs exhibit better hot-carrier (HC) reliability, better self-heating (SH) reliability, and better negative bias temperature (NBT) instability. Resulting from the heavily doped BG lines inside the active channel, lateral electric field reduction at the drain side, Joule heat… CONTINUE READING
