摘要:
A method for fabricating a radiation-cured structure is provided. The method includes the steps of providing a first radiation-sensitive material and a second radiation-sensitive material adjacent the first radiation-sensitive material. The first radiation-sensitive material has a first sensitivity. The second radiation-sensitive material has the first sensitivity and a second sensitivity different from the first sensitivity. At least one mask is placed between at least one radiation source and the first and second radiation-sensitive materials. The mask has a plurality of substantially radiation-transparent apertures. The first and second radiation-sensitive materials are then exposed to a plurality of radiation beams through the radiation-transparent apertures in the mask to form a first construct in the first radiation-sensitive material and a second construct in the second radiation-sensitive material. The first construct and the second construct cooperate to form the radiation-cured structure.

Compositions for use as immersion fluids are described. In general, the immersion fluids can be utilized to perform lithography at short wavelengths (e.g., in a range from about 120 nm to about 260 nm). Some embodiments can be used in a range of actinic radiation between about 140 nm and about 160 nm (e.g., about 157 nm). Immersion fluids can exhibit any number of advantageous features including a relatively high index of refraction (e.g., greater than about 1, or greater than about 1.3, or about greater than about 1.4) and/or a relatively low absorbance (e.g., lower than about 2 μm−1, or lower than about 1 μm−1, or lower than about 0.5 μm−1). Some immersion fluids can include silicon-containing compounds and/or germanium containing compounds. Such compounds can include at least one Ge—O bond or at least one Si—O bond. Such compounds can also include one or more fluorinated moieties.

A process for etching a metal or alloy surface which comprises applying an etch-resistant ink by ink jet printing to selected areas of the metal or alloy, exposing the etch-resistant ink to actinic radiation and/or particle beam radiation to effect polymerisation, optionally thermally treating the etch-resistant ink and then removing the exposed metal or alloy by a chemical etching process wherein the etch-resistant ink is substantially solvent-free and comprises the components: A) 30 to 90 parts acrylate-functional monomers; B) 0 to 50 parts metal adhesion promoting organic compound; C) 0 to 20 parts polymer and/or prepolymer; D) 0 to 20 parts radical initiator, E) 0 to 5 parts colorant; and F) 0 to 5 parts surfactant; wherein the ink has a viscosity of not greater than 200 cPs (mPa·s) at 40° C., all parts are by weight and the total number of parts A)+B)+C)+D)+E)+F)=100, provided that where the metal or alloy is supported by a non-etchable substrate, it does not constitute a printed circuit board.

A process is disclosed for the solvent-less development and production of flexographic printing plates. Relatively thin metal backed printing plate elements with a layer of photopolymer are selectively exposed to actinic radiation heated to at least 70° C. and then blotted to form a relief image. The process is particularly suited to the production of flexographic printing plates for printing newspapers and other publications.
摘要:
A method of projecting a pattern from a mask onto a substrate comprises providing an energy source, a substrate, and a mask containing a pattern of features to be projected onto the substrate, and projecting an energy beam from the energy source though the mask toward the substrate to create a projected mask pattern image. The projected mask pattern image is created by zeroth and higher orders of the energy beam. The method then includes diffracting zeroth order beams of the projected mask pattern image to an extent that prevents the zeroth order beams from reaching the substrate, while permitting higher order beams of the projected mask pattern image to reach the substrate. Preferably, the zeroth order beams of the projected mask pattern image are diffracted at an obtuse angle.
