  • Patent number: 10399851
    Abstract: A master tool is provided with an ink pattern on a major surface thereof. The ink pattern is formed by a screen printing process. A stamp-making material is applied to the major surface of the master tool to form a stamp having a stamping pattern being negative to the ink pattern of the master tool. The stamping pattern is inked with an ink composition and contacted with a metalized surface to form a printed pattern on a metalized surface of a substrate according to the stamping pattern. Using the printed pattern as an etching mask, the metalized surface is etched to form electrically conductive traces on the substrate.

  • Patent number: 10303053
    Abstract: Diazo-resin-containing photoresist compositions and methods of preparing the same are provided for solving the problem that existing diazo-resins cannot be applied in LCD photoresists because the storage periods of the diazo-resins themselves and the printed boards made thereby are both short due to poor thermal stability of the diazo-resins. The diazo-resins of the present invention have excellent thermal stability and exhibit strong resistance to dry etching when being used in negative photoresists, while high resolution can be achieved. Meanwhile, during exposure, portions of the diazo-resins can crosslink with hydrogen bonds on surface of SiO or SiON film forming a barrier layer or passivation layer, such that the adhesion between the photoresists and the film layer is increased, and the photoresists would not peel during development. Thus, the utilization of tackifiers for enhancing the adhesion between a photoresist and surface of SiO or SiON film before masking can be omitted.

  • Patent number: 6884561
    Abstract: A negative-working lithographic printing plate has a coating which is imaged by heating an area of the coating with an infrared laser and actinically reacting the coating in the heated area with ultraviolet or visible radiation. The coating contains an infrared absorber but the coating is not imageable by infrared radiation or by the heat generated. The imaging time is reduced since the actinic reaction rate is increased at the elevated temperature.
