- A direct photolithographic patterning method of regioregular poly(3-hexylthiophene) (rr-P3HT) as a semiconductive layer of organic field-effect transistors (OFETs) has been developed. The performance (0.092 cm²/Vs) of a bottom-contact type OFET using the patterned rr-P3HT as a semiconductive layer was almost the same as that (0.10 cm²/Vs) using the pristine rr-P3HT.
