  • Publication number: 20060208633
    Abstract: An organic electroluminescent device with improved lifetime and a method of fabricating the same are provided. The device comprises a barrier layer on an upper surface of a color filter, and etching and removing part of the barrier layer uncovered by first electrodes to form moistness removed channel after defining and forming at least one first electrode on an upper surface of the barrier layer. It is convenient to bake and eliminate a solvent or mist existed in the color filter in a baking process, thereby reducing speed of going bad of the organic light emitting layer and effectively improving lifetime of the organic electroluminescent device.

  • Publication number: 20050230711
    Abstract: A connecting circuit structure is provided for a circuit carrier. The circuit connecting structure includes at least two insulating layers, two conductive layers, and one conductive pad, wherein a via hole is formed from each of the insulating layers through corresponding insulating layer. One insulating layer is formed over the other. The conductive pad is disposed between the two insulating layers, and two surfaces of the conductive pad are connected to the two via holes respectively. Two conductive layers are respectively formed in the via hole on a same side of the circuit connecting structure in order to connect to the conductive pad respectively. Since a depth/width ratio of the via hole is reduced according to the circuit connecting structure in the present invention, voids and bubbles are effectively avoided and the reliability of fabricating method thereof is increased.

  • Patent number: 6395633
    Abstract: A method of forming a micro-via, for fabrication and design of a layout of a circuit board. A patterned conductive wiring layer is formed on the substrate. A copper layer is plated onto the substrate and the conductive wiring layer. A photoresist layer is formed on the copper layer. A part of the photoresist layer is removed to expose a part of the copper layer. Using the copper layer as a seed layer, a conductive pillar is formed on the exposed part of the copper layer. The photoresist layer is removed. The exposed plated copper layer is removed. An insulation layer is formed on surfaces of the substrate and the conductive pillar. A part of the insulation layer is removed to expose the conductive pillar. A patterned conductive wiring layer is formed on the conductive pillar.
