Summary:A new technology, which enables the transfer of thin films or thin
film devices from original substrate to any substrate by using laser
annealing, has been investigated. This technology was named SUFTLA which
stands for surface free technology by laser annealing. Low temperature
(⩽425°C) polycrystalline-silicon thin film transistors (poly-Si
TFTs) and TFT circuits could be successfully transferred from glass or
quartz substrate to plastic film. The circuit functionalities of CMOS
ring oscillators were not affected by this transfer
