“…2) On the other hand, thin-film transistors (TFTs) have been mainly applied in flat panel displays (FPDs), such as liquid crystal displays 3) and organic electroluminescence displays, 4) and area sensors. 5) In particular, since polycrystalline silicon (poly-Si) TFTs have high performance, they are expected to be applied to the system-on-panel (SOP) devices, such as integrated drivers, 6) in-pixel memories 7) and frame memories, 8) and general electronics, such as bipolar transistors, 9) sheet computers 10) and asynchronous microprocessor units. 11) Recently, the transfer technology of TFTs called surface free technology by laser ablation/annealing (Suftla) 12) has been developed, enabling TFTs and other thin-film devices to be transferred to any material substrates 13) and vertically stacked.…”
