  • Patent number: 6964793
    Abstract: A high-throughput lithography process for creating high-resolution patterns in a polymerizable composition using carefully controlled electric field followed by curing of the polymerizable composition is described. The process involves the use of a template that includes the desired patterns. This template is brought into close proximity to the polymerizable composition on the substrate. An external electric file is applied to the template-substrate interface while maintaining a uniform, carefully controlled gap between the template and substrate. This causes the polymerizable composition to be attracted to the raised portions of the template. By appropriately choosing the various process parameters such as the viscosity of the polymerizable composition, the magnitude of the electric field, and the distance between the template and substrate, the resolution of the structures formed in the liquid may be controlled to conform to that of the template.

  • Patent number: 6933020
    Abstract: A coating composition that can be used in a process for coating a substrate where in a first step a radiation curable coating composition is applied to the substrate and/or a radiation permeable film. Next, the substrate and the film are pressed together in such a way that the coating composition is sandwiched between them. Thereafter, the coating composition is cured by irradiation through the film to obtain a coated substrate. In a subsequent step, the film is removed from the coated substrate. The coating composition applied to the film and/or the substrate is a hot melt composition comprising 20 to 100 wt. % of a radiation curable resin or mixture of radiation curable resins having a viscosity in the range of from 15 to 10,000 mPa.s in the temperature range of from 40 to 150° C.

  • Patent number: 6933015
    Abstract: A method of forming a film of a coating solution on a substrate includes steps of moving a coating solution discharge member relative to a substrate while a coating solution is being discharged from the coating solution discharge member to the surface of the substrate, and changing a discharge direction of the coating solution to an outer peripheral portion of the substrate to make the amount of application to the outer peripheral portion smaller than that to other portions. This can reduce the amount of application to the outer peripheral portion of the substrate, thereby making it possible to restrain protuberance of the coating solution at the outer peripheral portion of the substrate caused by surface tension. Consequently, a coating film which is uniform also at the outer peripheral portion on the substrate is formed.

  • Patent number: 6899775
    Abstract: This invention relates to the printing of a substrate having a pre-printed “print pattern” with a “design layer” of ink where there is differential adhesion within and without the print pattern. The print pattern is receptive to an ink, and the design layer ink forms a durable image material with good bond to the print pattern, but the ink does not form a durable image material on the portions of the substrate outside the print pattern. The design layer ink is a UV-curable ink, and the print pattern may have a higher surface energy than the portions of the substrate outside the print pattern.

  • Patent number: 6849305
    Abstract: The invention is directed to a photoresist-free method for depositing films composed of metals, such as copper or silica, or their oxides from metal complexes. More specifically, the method involves applying an amorphous film of a metal complex to a substrate. The metal complexes have a metal and a photo-degradable ligand. A preferred ligand is acac or alkyl-acac, expecially in combination with acetate ligands. These films, upon, for example, thermal, photochemical or electron beam irradiation may be converted to the metal or its oxides. By using either directed light or electron beams, this may lead to a patterned metal or metal oxide film in a single step. Low temperature baking may be used to remove residual organics from the deposited film. If silica is the metal, the deposited film has excellent smoothness and dielectric properties.

  • Patent number: 6824816
    Abstract: The invention relates generally to processes for producing electrically conductive noble metal thin films on a substrate by atomic layer deposition. According to one embodiment of the invention a substrate with a surface is provided in a reaction chamber and a vaporised precursor of a noble metal is pulsed into the reaction chamber. By contacting the vaporised precursor with the surface of the substrate, no more than about a molecular layer of the metal precursor is formed on the substrate. In a next step, a pulse of molecular oxygen-containing gas is provided in the reaction chamber, where the oxygen reacts with the precursor on the substrate. Thus, high-quality metal thin films can be deposited by utilising reactions between the metal precursor and oxygen. In one embodiment, electrically conductive layers are deposited in structures that have high aspect ratio vias and trenches, local high elevation areas or other similar surface structures that make the surface rough.
