Transistor using organic material having a bridged cyclic hydrocarbon lactone structure and process for producing the same

摘要

An organic thin film transistor having an insulator layer formed of a polymer compound having a repeat unit represented by the following formula [1] is disclosed: wherein R¹, R² and R³ are each independently a hydrogen atom or a methyl group, R⁴ is a hydrogen atom or a linear, branched or bridged cyclic hydrocarbon group having 1 to 12 carbon atoms, and x and y are molar ratio and are any number satisfying x+y=1, 0<=x<=1 and 0<=y<1.
