摘 要:Processes to produce active-matrix backplanes on plastic substrates have been developed utilizing a- Si:H, multi-component oxide, and organic semiconductor technologies. The suitability of these technologies for future flat panel display applications is discussed. Of these material systems multi-component oxides exhibit highest field-effect mobilities (10cm2/Vs for zinc tin oxide demonstrated), followed by small molecule organic semiconductors (0.95 cm2/Vs), and a-Si:H (0.5 cm2/Vs). Yet despite higher mobilities, organic TFTs drive less current than a- Si:H because of the low device capacitances required to fabricate such devices. Backplanes made with a-Si:H appear to be the least risky technology, followed by multi-component oxide, and organic semiconductor technologies.
