Abstract

Large-area polymer FET arrays and integrated circuits (ICs) are successfully demonstrated via a simple wire-bar–coating process. Both a highly crystalline conjugated polymer layer and very smooth insulating polymer layer are formed by a consecutive wire-bar–coating process on a 4-inch plastic substrate with a short processing time for application as the active and dielectric layers of OFET arrays and ICs.
