摘要:
An electronic device includes a substrate, a structure having openings, and a first electrode overlying the structure and lying within the openings. From a cross-sectional view, the structure, at the openings, has a negative slope. From a plan view, each opening has a perimeter that may or may not substantially correspond to a perimeter of an organic electronic component. The portions of the first electrode overlying the structure and lying within the openings are connected to each other. In a process for forming the electronic device, an organic active layer may be deposited within the opening, wherein the organic active layer has a liquid composition.

In one embodiment, a containment structure (230) for an organic composition (240) is provided. The containment structure (230) includes an undercut layer (210) and an overlying layer (220), wherein the undercut (210) and overlying (220) layers define a volume for receiving the organic composition (240) in liquid form.
摘要:
A process for forming a layer of an electroactive material, including: depositing a liquid composition containing an electroactive material and at least one solvent onto a workpiece to form a wet layer; placing the wet layer on the workpiece into a vacuum chamber containing solid absorptive material; and treating the wet layer at a controlled temperature in a range of −25° C. to 80° C. and under an applied vacuum in a range of 10−6 Torr to 1,000 Torr for a period of 1-100 minutes.
摘要:
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.

There is provided a process for forming a layer of electroactive material having a substantially flat profile. The process includes: providing a workpiece having at least one active area; depositing a liquid composition including the electroactive material onto the workpiece in the active area, to form a wet layer; treating the wet layer on the workpiece at a controlled temperature in the range of −25 to 80° C. and under a vacuum in the range of 10−6 to 1,000 Torr, for a first period of 1-100 minutes, to form a partially dried layer; heating the partially dried layer to a temperature above 100° C. for a second period of 1-50 minutes to form a dried layer.
摘要:
There is provided a process for vacuum drying. The process includes the steps of: depositing a liquid composition containing a film-forming material and at least one solvent onto a workpiece to form a wet layer; placing the wet layer on the workpiece into a vacuum chamber including a condenser; and treating the wet layer at a controlled temperature in the range of −25 to 80° C. and under an applied vacuum in the range of 10−6 to 1,000 Torr for a period of 1-100 minutes; wherein the condenser is maintained at a temperature at which the solvent will condense as a liquid at the applied vacuum.
摘要:
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.
