Abstract
We exploited the concept of solvent orthogonality to enable photolithography for high-resolution, high-throughput fabrication of electronic circuits based on a polymeric semiconductor. An array of ring oscillators utilizing top contact polymer thin film transistors with 1 m channel length has been fabricated on a 100 mm wafer scale. We used high performance, air stable poly(2,5-bis(thiophene-2-yl)-(3,7-ditri-decanyltetrathienoacene) as our active semiconducting material. Owing to the small channel length and small overlap length, these devices have a signal propagation delay as low as 7 s/stage.
