Large-Swing a-IGZO Inverter With a Depletion Load Induced by Laser Annealing

In this letter, a high-performance inverter based on amorphous indium-gallium-zinc oxide thin-film transistors (TFTs) is fabricated, which consists of an enhancement mode driver and a depletion mode load. By applying an area-selective laser annealing technique, the threshold voltage (Vth) of the load TFT could be tuned from positive to negative gate voltage… CONTINUE READING
