Abstract:
Disclosed are a method for simultaneously forming a color filter overcoat and a column spacer of LCD and a negative photoresist composition usable therein. The method according to the present invention includes: (Sl) forming a photoresist film by applying a negative photoresist composition onto a substrate of a liquid crystal; (S2) exposing the photoresist film through a mask composed of a transflective region and a transmissive region; and (S3) forming a region of the photoresist film into a color filter overcoat and a column spacer, respectively. The method of the present invention may be useful to reduce the manufacturing cost and enhance a yield of a liquid crystal display since its manufacturing process can be easily reduced by simultaneously forming, on the color filter substrate, a column spacer and a color filter overcoat having a good shape and height difference.
Abstract:
In a lithographic proximity method for wiring an end or internal side surface of a substrate the required exposure of strips (76), defining the wiring pattern, is performed by means of a mask (70) comprising a diffraction structure (74) to deflect exposure radiation (b) to the side surface. An exposure beam, which is perpendicularly incident on the mask, is used so that enhanced tolerance for proximity gap width variations is obtained. The method allows manufacture of accurate and fine wiring.

Abstract:
A method and apparatus for exposing a substrate of relatively large surface area to radiation according to a predetermined pattern recorded on a mask, particularly useful in applying a painted border to an automobile windshield, includes the steps of progressively recording the predetermined pattern on a mask in the form of a continuous strip, and moving the radiation source to progressively scan the surface of the substrate with radiation, while at the same time moving the continuous strip mask relative to the radiation source, such that portions of the pattern on the continuous strip mask progressively become aligned with their corresponding portions of the substrate as the substrate is progressively scanned by the radiation source.
Abstract:
This application provides an exposure apparatus and relates to the field of exposure technologies. The exposure apparatus includes a conveying mechanism and an exposure mechanism. The conveying mechanism is configured to convey a substrate, a surface of the substrate being coated with photoresist. The exposure mechanism includes an exposure source and an exposure member. The exposure source is configured to provide light to the substrate. The exposure member includes an exposure section opposite the substrate, where the exposure section is located between the exposure source and the substrate and disposed in close proximity to the substrate, the exposure section has a light-transmitting portion that allows light to be incident on the substrate and a light-shielding portion that prevents light from being incident on the substrate, and the exposure section is configured to keep the light-transmitting portion and the light-shielding portion in synchronized movement with the substrate. The part of the exposure member provided with the light-shielding portion and the light-transmitting portion moves in synchronization with the substrate, implementing exposure processing by the exposure mechanism during conveying of the substrate, thus improving the exposure efficiency. During conveying of the substrate, the light-shielding portion and the light-transmitting portion remain stationary relative to the substrate, which ensures that the patterns on the exposure member are fully exposed to the substrate at a high speed with good pattern consistency.
Abstract:
The invention pertains to an exposure apparatus, a method for exposing a photosensitive element to radiation using the exposure apparatus, and a method for preparing a printing form from the photosensitive element. The exposure apparatus includes a base assembly having an exposure bed that supports the photosensitive element, and a lamp housing assembly having two or more lamps. The lamp housing assembly includes an air distribution assembly having an air chamber that is disposed adjacent to the lamps and pressurized to provide uniform distribution of air exiting the air chamber to impinge a backside of each of the lamps. The air exiting the chamber and impinging the lamps is controlled by monitoring the temperature of the lamps and/or the irradiance emitting from the lamps.
