Patent ID: 8426848

Claim:
An electronic device comprising: an organic semiconductor (OSC) layer ( 3 ), a gate electrode ( 5 ), a gate insulator layer ( 4 ) comprising a dielectric material, said gate insulator layer being located between the OSC layer ( 3 ) and the gate electrode ( 5 ), and optionally an additional insulator layer ( 6 ) covering the gate electrode ( 5 ) and the gate insulator layer ( 4 ), wherein the device further comprises at least one interlayer ( 7 ) between the gate insulator layer ( 4 ) and the gate electrode ( 5 ), or between the gate electrode ( 5 ) and the additional insulator layer ( 6 ), and wherein the interlayer ( 7 ) comprises a copolymer comprising at least one polar repeating unit and at least one unpolar repeating unit, wherein said at least one polar unit is a repeating unit of which the homopolymer has a surface energy ≧30 mN/m, and said at least one unpolar unit is a repeating unit of which the homopolymer has a surface energy ≦25 mN/m.
