  • Publication number: 20130120722
    Abstract: A method and a system for forming an alignment film region through ultraviolet (UV) light exposure are disclosed. The method comprises the following steps of: coating a polyimide (PI) solution on a substrate to form an alignment film that covers a predetermined alignment film region on the substrate; placing a mask—above the alignment film; peeling off portions of the alignment film on the substrate that are located outside the predetermined alignment film region through exposure to a UV light; and removing the mask to obtain the alignment film. The present disclosure can effectively improve-the problems of printing offsets, sawtooth-like edge irregularities and uneven film thicknesses caused when the alignment film region is coated by an alignment film inkjet printer. This improves the positioning precision of the alignment film region and the quality of the alignment film, thus improving the image quality of the LCD device.

Any residual liquid chemical agent remaining at the outlet of the spray nozzle from the processing of a previous substrate drops off harmlessly at the end of the downward vertical motion instead of dropping onto the film on the substrate.

The derivation includes micro-exposing subfields of the substrates with a pattern, processing the substrates at the various target conditions, determining photoresist-related characteristics of the subfields (e.g., Bossung curvatures), and extracting correlation information regarding the subfield characteristics and the different target processing conditions to relate the target conditions as a function of subfield characteristics. The method then detects non-uniformities in a micro-exposed subsequent substrate processed under production-level processing conditions and exploits the correlation information to adjust the production-level conditions and achieve uniformity across the substrate.

  • Publication number: 20110298730
    Abstract: Improved techniques are disclosed for fabrication of touch panels using thin sheet glass. Thin touch sensor panels each having a thickness of substantially less than approximately one-half millimeter can be produced. A thin mother glass sheet having a thickness of substantially less then approximately one half millimeter can be used. A thin film can be coupled to a surface of the thin mother glass sheet, and the thin film can be photolithographically patterned, while avoiding breakage of the thin mother glass sheet. The thin mother glass sheet can be singulated into the thin touch sensor panels.

  • Patent number: 8054443
    Abstract: A developing method is used for subjecting a light-exposed resist film disposed on a wafer W to a developing process by a developing solution and a rinsing process by a rinsing liquid. In a state where the resist film on the wafer W is wet with the developing solution or rinsing liquid before a drying process is performed on the wafer W, a chemical liquid (curing chemical liquid), which contains a resist curing aid contributory to curing of a resist film remaining on the wafer W, is supplied onto a surface of the wafer W. Then, ultraviolet rays are radiated onto a surface of the wafer to cure a resist film remaining on the wafer W by a synergistic effect of the resist curing aid and the ultraviolet rays thus radiated, so as to prevent pattern fall.

  • Patent number: 8040490
    Abstract: A liquid immersion exposure apparatus includes: a first optical member having an exit surface via which an exposure beam exits; a first movable body movable with respect to the first optical member while holding a substrate; a cover member movable with movement of the first movable body and capable of retaining a liquid in a space formed between the exit surface and the cover member when the cover member is arranged at a position opposite to the exit surface; a first holding portion provided on the first movable body and holding the cover member; and a transport section removing the cover member from the first holding portion and moving the cover member independently from the first movable body. Upon exposing the substrate through the liquid, it is possible to suppress the deterioration of the performance which would be otherwise caused due to the cover member.

  • Publication number: 20110249244
    Abstract: In order to determine whether an exposure apparatus is outputting the correct dose of radiation and its projection system is focusing the radiation correctly, a test pattern is used on a mask for printing a specific marker onto a substrate. This marker is then measured by an inspection apparatus, such as a scatterometer, to determine whether there are errors in focus and dose and other related properties. The test pattern is configured such that changes in focus and dose may be easily determined by measuring the properties of a pattern that is exposed using the mask. The test pattern may be a 2D pattern where physical or geometric properties, e.g., pitch, are different in each of the two dimensions. The test pattern may also be a one-dimensional pattern made up of an array of structures in one dimension, the structures being made up of at least one substructure, the substructures reacting differently to focus and dose and giving rise to an exposed pattern from which focus and dose may be determined.

  • Publication number: 20110205505
    Abstract: Disclosed is a method and apparatus for mitigation of photoresist line pattern collapse in a photolithography process by applying a gap-fill material treatment after the post-development line pattern rinse step. The gap-fill material dries into a solid layer filling the inter-line spaces of the line pattern, thereby preventing line pattern collapse due to capillary forces during the post-rinse line pattern drying step. Once dried, the gap-fill material is depolymerized, volatilized, and removed from the line pattern by heating, illumination with ultraviolet light, by application of a catalyst chemistry, or by plasma etching.
