Abstract:
There is provided a process for forming a contained second layer over a first layer. The process comprises forming the first layer having a first surface energy and then treating the first layer with a photocurable surface-active composition which is a fluorinated ester or fluorinated imide of an α,β-unsaturated polyacid; exposing the photocurable surface-active composition patternwise with radiation resulting in exposed areas and unexposed areas; developing the photocurable surface-active composition to remove the unexposed areas resulting in a first layer having untreated portions in the unexposed areas and treated portions in the exposed areas, where the treated portions have a second surface energy that is lower than the first surface energy; and forming the second layer on the untreated portions of the first layer. There is also provided an organic electronic device made by the process.
Abstract:
A process of forming an electronic device is disclosed. An organic device layer is formed. The organic device layer includes a charge-selective material and a radiation sensitizer and has a first electrical conductivity and a first surface energy. First portions of the organic device layer are selectively exposed to radiation. The electrical conductivity and surface energy of the first portions of the organic device layer are modified.
Abstract:
There is provided a process for forming a contained second layer over a first layer, including the steps: forming the first layer having a first surface energy; treating the first layer with a reactive surface-active composition to form a treated first layer having a second surface energy which is lower than the first surface energy; exposing the treated first layer with radiation; and forming the second layer. There is also provided an organic electronic device made by the process.
Abstract:
An apparatus and method for solution coating layers onto a substrate of an electronic device. A slot die coater in conjunction with a vacuum assist device is used in priming, coating and cleaning stations to produce thin layers having performance advantages over competing technologies.
Abstract:
There is provided herein a process for forming an encapsulated electronic device. The device has active areas and sealing areas on a substrate. The process includes providing the substrate; forming a discontinuous pattern of a material having a first surface energy on at least a portion of the sealing areas; forming multiple active layers, where at least one active layer is formed by liquid deposition from a liquid medium having a surface energy greater than the first surface energy; providing an encapsulation assembly; and bonding the encapsulation assembly to the substrate in the sealing areas. Also provided are devices formed by the disclosed processes.

Abstract:
There is provided a process for forming a contained second layer over a first layer, including the steps: forming the first layer having a first surface energy and a first glass transition temperature; condensing an intermediate material over and in direct contact with the first layer to form an intermediate layer, said intermediate layer having a second surface energy which is lower than the first surface energy; patterning the intermediate layer to form uncovered areas of the first layer and covered areas of the first layer; and forming a contained second layer over the uncovered areas of the first layer. There is also provided a process for making an organic electronic device.
