A slot‐die coating technique is used for the crystal alignment of triisopropylsilylethynyl (TIPS)‐pentacene in solution‐processed field‐effect transistors (FETs). The film thickness, uniformity, and crystal growth behavior are well controlled by tuning the coating parameters and by using a mixed solvent system (toluene/anisole). An average saturation regime FET mobility of 1.8 cm 2 V −1 s −1 is achieved under ambient conditions.
