Patent ID: 7298023

Claim:
In an electronic device comprising at least one of an organic field effect transistor or capacitor, which transistor and capacitor comprises an insulator layer and includes electrical and mechanical requirements and which insulating layer fulfills the electrical and mechanical requirements of the transistor or capacitor, the improvement comprising: the insulating layer being at least partially based on organic material, and wherein the dielectric constant of the insulating layer remains substantially constant within a frequency range between 1 Hz and 100 Hz; the insulator layer comprising a base polymer of PVDC-PAN-PMMA copolymer with the general formula (—CH 2 Cl 2 —) x —(—CH 2 CH(CN)—) y —(CH 2 C(CH 3 )(CO 2 CH 3 )—) z , wherein x, y, z, in each case, independently from one another, may assume values between 0 and 1.
