Methods and compositions for obtaining patterned structures comprising fluorine-containing polymeric materials. The fluorine-containing polymeric materials have sufficient fluorine content such that the materials can be patterned using conventional photolithographic/pattern transfer methods and maintain desirable mechanical and physical properties. The patterned structures can be used, for example, in light-emitting devices.

An object of the present invention is to provide forceps for removing a dental implant fixture, in which pinching portions securely hold a fixture to remove the fixture implanted in an alveolar bone, and thus to prevent the pinching portions from slipping out of the fixture. Forceps for removing a dental implant fixture according to the exemplary embodiment of the present invention include: a pair of handles; coupling portions extended from the handles, crossed, and hingedly coupled; pinching portions connected to the coupling portions; and holding pieces protruding from ends of the pinching portions in a direction toward a center of a dental implant fixture and each having an arc corresponding to at least a part of an outer circumference of the fixture so that the holding pieces are inserted into a trough of a threaded portion formed on the outer circumference of the fixture.
摘要:
A method for patterning biomaterials is presented. The biomaterials exhibit biological activity after patterning. The use of bio-compatible imaging materials and solvents allows conventional lithographic patterning methods to be applied to patterning biomolecules. The method allows deposition of multiple layers without subsequent layers affecting earlier laid deposits and can pattern multiple different biomolecules on a single surface.
摘要:
An orthogonal process for photolithographic patterning organic structures is disclosed. The disclosed process utilizes fluorinated solvents or supercritical CO2 as the solvent so that the performance of the organic conductors and semiconductors would not be adversely affected by other aggressive solvent. One disclosed method may also utilize a fluorinated photoresist together with the HFE solvent, but other fluorinated solvents can be used. In one embodiment, the fluorinated photoresist is a resorcinarene, but various fluorinated polymer photoresists and fluorinated molecular glass photoresists can be used as well. For example, a copolymer perfluorodecyl methacrylate (FDMA) and 2-nitrobenzyl methacrylate (NBMA) is a suitable orthogonal fluorinated photoresist for use with fluorinated solvents and supercritical carbon dioxide in a photolithography process. The combination of the fluorinated photoresist and the fluorinated solvent provides a robust, orthogonal process that is yet to be achieved by methods or devices known in the art.

摘要:
The present invention provides a method for forming an organic device having a patterned conductive layer that includes providing a substrate, depositing organic materials over the substrate to form one or more organic layers, coating a photoresist solution over the one or more organic layers to form a photo-patternable layer, wherein the solution includes a fluorinated photoresist material and a first fluorinated solvent, selectively exposing portions of the photo-patternable layer to radiation to form a first pattern of exposed fluorinated photoresist material and a second pattern of unexposed fluorinated photoresist material, exposing the substrate to a second fluorinated solvent to develop the photo-patternable layer, removing the second pattern of unexposed fluorinated photoresist material without removing the first pattern of exposed fluorinated photoresist material, coating one or more conductive layers over the one or more organic layers and removing a portion of the one or more of the conductive layers to form a pattern. Particular embodiments of the present invention for forming arrays of top contact TFTs and a pixilated organic device are also provided.

A method is provided for forming a multi-color OLED device that includes providing a substrate, coating the substrate with a fluorinated photoresist solution to form a first photo-patternable layer and exposing it to produce a first pattern of exposed fluorinated photoresist material and a second pattern of unexposed fluorinated photoresist material, developing the photo-patternable layer with a fluorinated solvent to remove the second pattern of unexposed fluorinated photoresist material without removing the first pattern of exposed fluorinated photoresist material, depositing a first organic light-emitting material over the substrate to form a first organic light-emitting layer for emitting a first color of light and applying the first pattern of exposed fluorinated photoresist material to control the removal of a portion of the first organic light-emitting layer. A second fluorinated photoresist solution is then coated over the first patterened organic light-emitting layer and exposed to form a third pattern of exposed fluorinated photoresist material having a pattern different from the first pattern and a fourth pattern of unexposed fluorinated photoresist material, and developing the photo-patternable layer in a fluorinated solvent to remove the fourth pattern of unexposed fluorinated photoresist material without removing the third pattern of exposed fluorinated photoresist material, depositing at least a second light-emitting material to form a second light-emitting layer for emitting a second color of light that is different than the first color of light and applying the third pattern of exposed fluorinated photoresist material to control the removal of a portion of the second organic light-emitting layer.
