Patent ID: 8288762

Claim:
An organic field effect transistor having a structure of a conductor layer/an insulator layer/a semiconductor layer; wherein the transistor comprises an insulator layer formed by mixing (i) a polymer compound produced by polymerizing or copolymerizing a monomer represented by the formula (1): CH 2 â•CHCOOâ€”(CH 2 ) 2 â€”CNâ€ƒâ€ƒ(1), and/or a monomer represented by the formula (2): CH 2 â•C(CH 3 )COOâ€”(CH 2 ) 2 â€”CNâ€ƒâ€ƒ(2) and (ii) a polymerizable and/or crosslinkable organic compound other than the monomer represented by the formula (1) or (2); and a semiconductor layer comprising an organic compound.
