Abstract
A method of manufacturing a multi-layer circuit layer is provided. One example method includes the steps of: preparing an upper substrate and a lower substrate, wherein each of the upper and lower substrates includes a carrier layer and a seed layer, which are detachably connected to each other; forming circuits including first circuit patterns on the upper substrate and second circuit patterns on the lower substrate by plating on the seed layer; preparing a core substrate, wherein circuit patterns comprising a conductive material are formed on the core substrate; coupling the upper substrate, the core substrate, and the lower substrate by interposing adhesive members; detaching the carrier layer from the seed layer; etching the seed layer, wherein the seed layer is removed; and electrically connecting the first circuit patterns and the second circuit patterns to the third circuit patterns, respectively.
