PROBLEM TO BE SOLVED: To obtain an integrated CMOS circuit which requires preparation or evaporation of two different materials for forming a complementary device. SOLUTION: A CMOS integrated circuit is composed of thin film transistors of semiconductor formed of ambipolar organic material. Suitable material is tetracene and pentacene. In these CMOS devices, a uniform layer of tetracene or pentacene can be used in both an N-type (inversion) device and a P-type (accumulation) device.
