Patent ID: 8883546

Claim:
A process for preparing an organic electronic (OE) device, comprising the steps of depositing an insulator layer comprising a cross-linkable dielectric material onto a substrate or onto another layer of said OE device, exposing one or more areas of the insulator layer to a first radiation dosage, or to a first thermal energy, that causes partial but not complete cross-linking of the dielectric material, wherein the cross-linking is sufficient to provide solvent resistance, exposing one or more, but not all, areas of the insulator layer to a second radiation dosage, or to a second thermal energy, that causes a higher degree of cross-linking of the dielectric material than the exposure to the first radiation dosage or the first thermal energy, depositing an organic semiconductor (OSC) layer onto at least a part of the insulator layer, so that the OSC layer is in direct contact with at least a part of the areas of the insulator layer having a higher degree of cross-linking of the dielectric material.
