Abstract: The shapes of the photo-resist layer “banks” which define pockets for inkjet printing or other patterned processes are optimized to provide a more uniform drying profile for substances which are to be deposited in those pockets and dried therein. Preferably, the shapes of the banks are “mushroom” shaped such that a portion of the photo-resist layer overhangs the exposed lower electrode layer.

Abstract: The composition of a organic (e.g. conducting polymer) solution is reformulated and the device upon which the organic solution is to be deposited is plasma treated to provide a more uniform and flat drying profile for the resulting dried film. This reformulation and treatment induces a more uniform and flatter profile when the reformulated organic solution is allowed to dry into a film on the treated device.

Abstract: The height of the photo-resist layer “banks” which define pockets for inkjet printing or other patterned processes is optimized to provide a more uniform drying profile for substances which are to be deposited in those pockets and dried therein. Preferably, the height of the photo-resist layer is less than or equal to about three microns and more, preferably, about one micron.

Abstract: A method and an apparatus for obtaining measurements of eccentricity in optical fibers, from which the spin imparted to the optical fiber can be ascertained. The method and apparatus enable eccentricity to be measured in such a way that this measurement can be utilized to determine the amount of spin imparted to an optical fiber as the optical fiber was being drawn, although the eccentricity measurement may be used for purposes other than to determine the amount of spin in the fiber. By viewing the fiber from one or more positions along the length of the fiber, the eccentricity of the fiber as a function of position along the length of the fiber can be determined. The amount of spin in the fiber can then be determined from the eccentricity measurement.

Abstract: In accordance with the invention, a method for fabricating an organic electronic device is disclosed. The method consists primarily of 1) depositing a first organic solution by inkjet or other techniques, 2) cross-linking the deposited and dried (or partially dry or not dried organic film resulting therefrom, and then 3) depositing a second organic solution over the cross-linked film.

Abstract: A precipitation agent is deposited on a lower electrode layer of an organic electronic device prior to fabrication of organic layers. After the precipitation agent is deposited, organic material is deposited over the precipitation agent. The precipitation agent induces a more uniform and flatter profile when the organic material is allowed to dry into a film on the treated surface.

Preferably, the height of the photo-resist layer is less than or equal to about three microns and more, preferably, about one micron.

Abstract: An organic polymer solution is made of at least one organic polymer, a first solvent, and a second solvent. The first solvent has a high solubility (e.g., the first solvent dissolves at least about one weight percent of the organic polymers) and has a faster evaporation rate than the second solvent, and the second solvent has a very low solubility (e.g., the second solvent dissolves less than about one-fourth weight percent of the organic polymers). After the solution is deposited on an object, the solution is allowed to dry. As the solution dries, the first solvent due to its faster evaporation rate than the second solvent starts to evaporate from the solution, and soon after the first solvent starts to evaporate, the one or more organic polymers, due to its lower solubility in the second solvent, rapidly gels resulting in a substantially uniform organic polymer layer.
