  • Publication number: 20060016553
    Abstract: A method of fabricating a high density printed circuit board by applying a strippable adhesive layer on a reinforced substrate (rigid substrate or carrier film) used as a base substrate, forming a metal foil on the adhesive layer by means of plating, lamination or sputtering, and forming a high density circuit on the metal foil serving as a seed layer by means of pattern plating. Specifically, the method of the current invention includes the steps of attaching adhesive means to one surface of a reinforced substrate (rigid substrate or carrier film), forming a seed layer on the adhesive means and forming a circuit pattern on the seed layer, laminating an insulating layer on the circuit pattern and removing the reinforced substrate (rigid substrate or carrier film), and removing the seed layer.

  • Patent number: 6933995
    Abstract: An LCD device includes a transparent glass plate 122 and thin film transistor electrodes 124 formed on the glass plate 122. A photosensitive insulation film 128 is coated on the glass plate 122 and the thin film transistor electrodes 124. The insulation film 128 includes transparent and reflective regions 134 and 133 which are different in thickness. Light shielding films 126 are positioned underneath boundaries of the transparent and reflective regions 134 and 133. Where an optical exposure stage includes different reflection coefficient portions, the light shielding films 126 prevent light reflected by the exposure stage from reaching the insulation film thereby maintaining the accuracy of its patterning.

  • Patent number: 6873174
    Abstract: A first signal line and a second signal line are paired, and in one signal line selection period, CPU of the inspection circuit controls a write circuit and writes analog signals into the first signal line selected by means of a switch of the selection circuit. In the next signal line selection period, CPU controls a read circuit and reads output signals from the second signal line selected by means of the switch. CPU detects a short circuit between the paired signal lines based upon the output signals from the second signal line.

  • Publication number: 20040238370
    Abstract: A method of manufacturing a printed circuit board is disclosed. A seed layer is removed while etching of a circuit pattern is prevented. In a printed circuit board manufacturing process according to a semi-additive method, a seed layer is formed by electroless copper plating. Using a resist pattern, a circuit pattern is formed by electrolytic copper plating. After the formation of the circuit pattern, the exposed regions of seed layer are subjected to etching. According to the invention, an etching liquid at a temperature of about 15° C. or less is used. As a temperature of the etching liquid is lowered, a potential difference between the seed layer and the circuit pattern increases. Due to the increase in potential difference, the seed layer becomes more susceptible to being etched, while the circuit pattern becomes less susceptible to being etched.
