An 8V organic complementary logic process for flexible polymeric substrates

We have designed and fabricated the first organic complementary integrated circuits on a flexible substrate. Pentacene and hexadecafluorocopperphthalocyanine (F₁₆CuPc) were used as the p-type and n-type organic semiconductors, and solution-processed polyvinylphenol was used as the gate dielectric. Transistors and circuits operate with a supply voltage as low as 8 V, and ring oscillators have a signal propagation delay as low as 8 μsec per stage. To our knowledge, these are the fastest organic complementary circuits reported to date.
