摘 要:The potential of the screen printing method for large-scale production of organic electrochemical transistors(OECTs),combining high production yield with low cost,is here *** screen-printed OECTs of 1 mm^(2) area,based on poly(3,4-ethylenedioxythiophene)doped with poly(styrensulfonate)(PEDOT:PSS),have been manufactured on flexible polyethylene terephthalate(PET)*** goal of this project effort has been to explore and develop the printing processing to enable high yield and stable transistor parameters,targeting miniaturized digital OECT circuits for large-scale integration(LSI).Of the 760 OECTs manufactured in one batch on a PET sheet,only two devices were found malfunctioning,thus achieving an overall manufacturing yield of 99.7%.A drain current ON/OFF ratio at least equal to 400 was applied as the strict exclusion principle for the yield,motivated by proper operation in LSI *** consistent performance of low-footprint OECTs allows for the integration of PEDOT:PSS-based OECTs into complex logic circuits operating at high stability and accuracy.
