Abstract: The present invention relates to a thick-film pattern structure formed by repeating a stacking process, specifically a thick-film pattern structure having a reduced taper angle at a pattern edge region after all layers of the same material are stacked in gradually reducing pattern widths, and a method of forming the thick-film pattern structure. The thick-film pattern structure according to the present invention comprises a thick-film pattern coating layer having a pattern width; and multiple thick-film pattern coating layers sequentially stacked on the thick-film pattern coating layer to have gradually reducing pattern widths at an edge region of the thick-film pattern coating layers, wherein the thick-film pattern coating layers provide a thick-film pattern having a stepped shape.

Abstract: Provided are a high-performance touch sensor and a method of manufacturing the same. The touch sense includes a substrate, a sense electrode part formed on the substrate, and an insulating layer formed on the sense electrode part. A pitch of a unit sense cell including the sense electrode part is in a range of 50 μm to 70 μm. A dielectric constant of the insulating layer is in a range of 6 to 10. A unit sense cell pitch and a mutual capacitance sufficient for stably identifying a user's fingerprints may be achieved and both light transmittance and visibility may be improved.

Abstract: The present invention relates to a high-performance film-type touch sensor that has a low sheet resistance and can have a high resolution, a large area, and a small thickness, and a method of fabricating the same. In the high-performance film-type touch sensor which is peeled off from a substrate and to which a base film is bonded, at least a separation layer, an electrode pattern layer, and a protection layer are sequentially stacked on the base film, and one or more of first and second electrode patterns arranged in different directions on the separation layer are formed of a plurality of conductive layers to reduce sheet resistance.
