  • Patent number: 9105628
    Abstract: Through substrate via (TSuV) structures and method of making the same are disclosed herein. In embodiments, TSuV structures are metal filled selectively to avoid forming significant metal overburden on non-via surfaces of the substrate. In certain embodiments, post-fill metal removal/planarization operations are eliminated for reduced process complexity and manufacturing cost. In embodiments, selective metal fill entails selective electroless or electrolytic deposition. Both front side and back side selective deposition methods are described along with features of through substrate via structures made with such methods.

  • Patent number: 6706463
    Abstract: A method for making a lithographic printing plate comprises the steps of imagewise exposing, to a laser beam, a PS plate comprising a substrate, a heat-sensitive layer containing at least one light-heat conversion agent and a binder polymer formed on the substrate and a hydrophilic or lipophobic layer applied onto the heat-sensitive layer; and then removing the hydrophilic or lipophobic layer on the laser-exposed area by developing the imagewise exposed printing plate within 120 seconds from the completion of the laser-exposure to thus give a lithographic printing plate, wherein the developing treatment comprises the step of rubbing the exposed printing plate surface with an abrasion means in the absence of any liquid. This method permits the production of a lithographic printing plate without causing any deterioration of the developing properties of the PS plate even when the imagewise exposed PS plate is developed within a short period of time after the completion of the laser-exposure.

    Abstract: In a developing processing method and apparatus in which developing processing is carried out in such a manner that a processing solution is jetted from jetting holes to an emulsion surface of a photosensitive material, a hole diameter of the jetting holes is set to be 0.5 mm to 0.9 mm. In this case, clogging of the jetting holes does not easily occur and the processing solution can be jetted from the jetting holes stably for a long period of time. Accordingly, non-uniform processing is rarely caused. Intervals between the jetting holes in the transverse direction of the photosensitive material are each in a range of 3.0 mm to 4.5 mm. The jetting holes are disposed in such a manner that jetting holes of adjacent three rows in a direction in which the photosensitive material is conveyed are located at different positions to form a staggered arrangement, and the three rows of jetting holes are formed repeatedly.

  • Patent number: 4853320
    Abstract: A method of locally providing metal on a surface of a substrate, in which the substrate is provided at the surface with an electrocatalythic image. The surface is then brought into contact with an electroless metal-plating solution. The electrocatalythic image is capable of binding metal to it from the metal-plating solution. Due to the fact that the image is brought into contact with the metal-plating solutin, the image is gradually strengthened with metal from the solution. With images smaller than 10 .mu.m, this strengthening is prevented, however, due to the fact that oxygen is present in the solution. Because oxygen is reduced, a reduction of metal ions in the solution cannot occur, as a result of which no metal deposition takes place on the image. According to the invention, the reduction of oxygen in the solution is counteracted at least relatively so that also in the case of images smaller than 10 .mu.m metal ions are reduced without hindrance to the metal, which is then deposited on the image.

  • Patent number: 4282314
    Abstract: A mask for selectively transmitting therethrough a desired light radiant energy is disclosed. The mask comprises a stress-relieved, essentially dimensionally stable base, comprising a copolymer of tetrafluoroethylene and hexafluoropropylene, which is capable of transmitting therethrough the light radiant energy. A blocking film is deposited on at least a portion of the base for blocking the transmission of the light radiant energy through the portion of the base.

  • Patent number: 4251623
    Abstract: Tellurium images are formed by the decomposition of tellurium (II) coordination complexes in the presence of a catalyst. The complexes are characterized in that at least one of the four coordination positions of the tellurium (II) is occupied by a sulfur containing ligand. Preferred ligands that can be coordinated with tellurium are sulfur containing bidentate anionic ligands. Complexes formed using these preferred ligands are more hydrolytically stable than other tellurium (II) complexes having sulfur containing ligands and yet are still capable of providing catalytic amplification.

  • Patent number: 4230788
    Abstract: A method of making an electrically conducting metal pattern on a superficially non-conducting support which comprises imagewise exposing to light a photosensitive material containing either a diazosulfide or a diazosulfonate, which produces a light reaction product which is capable of forming free silver and mercury metal from water-soluble silver and mercurous compounds. A mixture of water and at least one solvent from the group consisting of chloroform, toluene, ethylacetate, liquid alcohols and ketones is used in the treatment of the exposed photosensitive material to form a latent image.

  • Patent number: 4225658
    Abstract: A process is disclosed for producing an ultrasonographic image using an element containing a catalyst and a diffusion barrier. When the element is placed into contact with a solution containing a catalyst poison and ultrasound is imagewise applied, the catalyst is selectively poisoned in ultrasonically exposed areas. Thereafter the unpoisoned catalyst remaining is employed to form a viewable image. The catalyst can be electrically biased to avoid poisoning during extended contact with the catalyst poisoning solution in the absence of ultrasound. In one form the catalyst can be generated using a photographic silver halide emulsion.

  • Patent number: 4192764
    Abstract: A method for depositing a metal on a surface is disclosed. The method comprises treating the surface with a sensitizing solution comprising at least a reducible salt of a non-noble metal and a radiation-sensitive reducing agent for the salt to form a sensitized surface. The sensitized surface is exposed to a source of light radiation to reduce the metal salt to a reduced metal salt species. Either or both of the preceding sensitizing or radiation exposing steps is restricted to a selected pattern on the surface to form a catalytic real image capable of directly catalyzing the deposition of a metal thereon from an electroless metal deposition solution. The catalytic real image is treated with a stabilizer comprising (a) a reducing agent for the non-noble metal ions of said reducible salt, (b) a complexing agent and (c) an accelerator to at least stabilize the catalytic real image.
