    摘要: A device comprising a stack of layers defining one or more electronic elements, wherein the stack comprises at least: one or more semiconductor channels; a dielectric; a first conductor pattern defining one or more coupling conductors, wherein the one or more coupling conductors are capacitively coupled to the one or one or more semiconductor channels via the dielectric; a planarisation layer; a second conductor pattern defining one or more routing conductors, wherein the second conductor pattern is in contact with the first conductor pattern via through holes in at least the planarisation layer, and wherein the semiconductor channel regions are at least partly outside the through hole regions.

    摘要: The present invention relates to a process for the preparation of a top-gate, bottom-contact organic field effect transistor on a substrate, which organic field effect transistor comprises source and drain electrodes, a semiconducting layer, a cured first dielectric layer and a gate electrode, and which process comprises the steps of: i) applying a composition comprising an organic semiconducting material to form the semiconducting layer, ii) applying a composition comprising a first dielectric material and a crosslinking agent carrying at least two azide groups to form a first dielectric layer, iii) curing portions of the first dielectric layer by light treatment, iv) removing the uncured portions of the first dielectric layer, and v) removing the portions of the semiconducting layer that are not covered by the cured first dielectric layer, wherein the first dielectric material comprises a star-shaped polymer consisting of at least one polymer block A and at least two polymer blocks B, wherein each polymer block B is attached to the polymer block A, and wherein at least 60 mol % of the repeat units of polymer block B are selected from the group consisting of Formulas (1A), (1B), (1C), (1D), (1E) and (1F), wherein R1, R2, R3, R4, R5, R6, R7 and R8 are independently and at each occurrence H or C1-C10-alkyl.
