Y. Q. Liu, W. P. Hu, and co‐workers demonstrate on page 4683 that the channel lengths of inkjet‐printed transistors can be reduced to a sub‐micrometer scale via a simple and direct method, without any sophisticated substrate‐treatments with photolithography and organosilanes. By inkjet printing solvents on ultrathin poly(methyl methacrylate) (PMMA), channel regions with high resolution are welldefined. With an inkjet‐printed polymeric semiconductor, this technique provides a short‐cut to low‐cost, massfabrication of photodetectors with ultrahigh responsivity.
