  • SPUTTER PROTECTIVE LAYER FOR ORGANIC ELECTRONIC DEVICES
    Publication number: 20210119157
    Abstract: The present invention provides an organic gate insulator (OGI) layer having a low dielectric constant (k), said organic gate insulator layer being over-coated with a cross-linked organic layer (OSPL) having a relatively high permittivity (k). The present invention also provides an electronic device comprising such an organic thin film transistor. The invention also provides a solution for producing said OSPL, and a process for producing said OSPL.

  • Organic field effect transistor with an organic dielectric
    Patent number: 7029945
    Abstract: A process of manufacturing an organic field effect device is provided comprising the steps of (a) depositing from a solution an organic semiconductor layer; and (b) depositing from a solution a layer of low permittivity insulating material forming at least a part of a gate insulator, such that the low permittivity insulating material is in contact with the organic semiconductor layer, wherein the low permittivity insulating material is of relative permittivity from 1.1 to below 3.0. In addition, an organic field effect device manufactured by the process is provided.
