Abstract:
Development of resists are useful, for example, to form a patterning mask in the context of high-resolution patterning. Development can be accomplished using an organic vapor such as a carboxylic acid. In some implementations, the organic vapor is trifluoroacetic acid. In some implementations, the organic vapor is hexafluoro-acetylacetone. A metal-containing resist film such as an EUV-sensitive organo-metal oxide may be deposited on a semiconductor substrate using a dry or wet deposition technique. The metal-containing resist film on the semiconductor substrate may be developed using the organic vapor, or residue of metal-containing resist material formed on surfaces of a process chamber may be removed using the organic vapor.
Abstract:
The present disclosure relates to a film formed with a tantalum-based precursor, as well as methods for forming and employing such films. The film can be employed as a photopatternable film or a radiation-sensitive film. In non-limiting embodiments, the radiation can include extreme ultraviolet (EUV) or deep ultraviolet (DUV) radiation.
Abstract:
The invention relates to a process for the preparation of a substrate coated with a relief structure comprising the steps of a) coating a substrate with a coating composition comprising a polymeric binder, a photoinitiator and a compound having at least two crosslinkable groups per molecule to form a coated substrate and b) exposing said coated substrated to a pulsed light while moving said coated substrate with respect to the pulsed light to obtain a substrate coated with a relief structure. The invention also relates to films, tapes and fibres obtained with said process and to use of these films, tapes and fibres in various applications.
Abstract:
A heating step is performed in a printing operation where a gas jet emitting from a nozzle assembly impinges the exterior surface of a printing plate. The gas impingement provides rapid and specific convective heat flux to the exterior surface of the printing plate.
Abstract:
A method of making a patterned dried polymer from a polymer solution or polymer dispersion, the method comprising the step of placing a mask above the polymer solution/dispersion so that there are exposed areas of polymer solution/dispersion and unexposed areas of polymer solution/dispersion, and irradiating the masked polymer solution/dispersion with infrared radiation.
Abstract:
The invention relates to a process for the preparation of a polymeric relief structure comprising the steps of coating a substrate with a coating composition comprising one or more radiation-sensitive ingredients, locally treating the coated substrate with electromagnetic radiation having a periodic or random radiation-intensity pattern, forming a latent image, and polymerizing and/or crosslinking the resulting coated substrate, wherein the coating composition comprises one or more radical scavengers in an amount sufficient to inhibit/retard substantial polymerization in the non-treated areas of the coated substrate, and low enough to allow polymerization and/or crosslinking in the treated areas in step c, with the proviso that the amount of oxygen present in the coating composition is not equal to the equilibrium amount of oxygen present when the coating composition is in contact with air.
Abstract:
An improved flexo processor and a method of using the improved flexo processor to increase the flexibility of both the type and the size of the flexographic printing element that may be processed. The novel thermal plate processor system is capable of processing both flat and round photosensitive printing elements with only minimal changes to the system. The thermal plate processor system may also include means for exposure and post-exposure/detack in the same system.
