  • Patent number: 7033735
    Abstract: A method is described for reducing the space width of holes in a first resist pattern and simultaneously removing unwanted holes to change the pattern density in the resulting second pattern. This technique provides holes with a uniform space width as small as 100 nm or less that is independent of pattern density in the second pattern. A positive resist is patterned to form holes with a first pattern density and first space width. A water soluble negative resist is coated over the first resist and selectively exposed to form a second patterned layer consisting of water insoluble plugs in unwanted holes in the first pattern and a thin water insoluble layer on the first resist pattern in unexposed portions. The plugs may form dense and isolated hole arrays while the thin insoluble layer reduces space width to the same extent in remaining holes in the second pattern.

    Abstract: An ink transfer sheet and method for using the same. The transfer sheet includes a backing layer, a release layer on the backing layer, and an ink receiving layer on the release layer. The ink receiving layer contains a quaternary ammonium salt thereon or impregnated therein. To use the transfer sheet, an ink containing an anionic coloring agent is applied to the ink receiving layer, preferably using thermal inkjet methods. Thereafter, the transfer sheet is positioned on a fabric substrate. Heat is applied to the sheet which causes the release layer and ink receiving layer to adhere to the substrate. The backing layer is then detached from the release layer leaving the release and ink receiving layers (with the printed image thereon) on the substrate. This process transfers the image to the fabric substrate, with the image being stabilized by interactions between the quaternary ammonium salt and anionic coloring agent.

    Abstract: In the manufacture of a screen suitable for use as a rear projection screen, a first layer (10) of a photopolymerisable monomer or oligomer which is tacky in its monomeric or oligomeric form and non-tacky in its polymerised form, is exposed to polymerising light, such as ultra-violet light, in a pattern comprising an array of spots of such light, and consequent selective polymerisation is allowed to take place in the first layer (10). There is then applied to the exposed surface of the first layer (10) a printing medium comprising an opaque pigment layer (28) on a supporting substrate (30) so that the pigment layer (28) contacts the exposed surface of the first layer (10) and sticks to the unpolymerised and therefore still tacky regions of the first layer (10), but not to the polymerised regions. The substrate (30) carrying the pigment layer (28) is then stripped from the first layer (10), leaving pigment (28) adhering only to the unpolymerised regions.

  • Patent number: 5409800
    Abstract: A photosensitive transfer material comprises a temporary substrate having provided thereon an alkali-soluble thermoplastic resin layer, an intermediate layer, and a photosensitive resin layer in this order, the interlaminar adhesion in the transfer material being the smallest at the interface between the thermoplastic resin layer and the temporary substrate. The photosensitive resin layer can be transferred to a permanent substrate without involving failure due to fine dust, air bubbles or unevenness of the permanent substrate. An image can be formed with the transfer material by adhering the transfer material to a permanent substrate at least under heat and, after stripping the temporary substrate, imagewise exposing the photosensitive resin layer to light, and processing the transferred layers to develop the photosensitive resin layer.

  • Patent number: 5378583
    Abstract: In the formation of microstructures, a preformed sheet of photoresist, such as polymethylmethacrylate (PMMA), which is strain free, may be milled down before or after adherence to a substrate to a desired thickness. The photoresist is patterned by exposure through a mask to radiation, such as X-rays, and developed using a developer to remove the photoresist material which has been rendered susceptible to the developer. Micrometal structures may be formed by electroplating metal into the areas from which the photoresist has been removed. The photoresist itself may form useful microstructures, and can be removed from the substrate by utilizing a release layer between the substrate and the preformed sheet which can be removed by a remover which does not affect the photoresist. Multiple layers of patterned photoresist can be built up to allow complex three dimensional microstructures to be formed.

  • Patent number: 5366837
    Abstract: An image receiving sheet of the present invention for receiving a desired image thereon includes a support layer and an absorbing layer containing heat-meltable or thermoplastic particles. A desired image can be formed in the absorbing layer of the image receiving sheet. Through heating the image receiving sheet formed with the desired image, the heat-meltable or thermoplastic particles are thermally melted or softened to attain a glossy and transparent surface formed with the desired image. As a result, an image bearing product coated with a glossy and transparent surface formed with the desired image is obtained. Through thermally pressing the image receiving sheet formed with the visible image toward an article of arbitrary type, on the other hand, the heat-meltable or thermoplastic particles are thermally melted or softened to be adhered to a surface of the article, so that the desired image is transferred onto the surface of the article.

  • Patent number: 5304453
    Abstract: A method of preparing a fine pattern on a substrate characterized by the dry development of a photoimaged, etch resistant pattern on a receiver substrate. The pattern is transferred from a carrier substrate to the receiver substrate via a hardenable liquid adhesive. This method eliminates adverse reflection effects caused from substrate topography in single layer photoresist systems and also avoids time consuming multiple coatings in multilayer photoresist systems used to make fine patterns. The method is particularly useful in the fabrication of integrated circuits and fine dimension patterns.
