Abstract:
1. A method of manufacturing a substrate using a carrier, comprising: forming an adhesive layer on at least one side of a base plate; forming an auxiliary adhesive layer on the adhesive layer, the auxiliary adhesive layer having lower adhesivity and a smaller area than the adhesive layer wherein the adhesivity of the side toward the adhesive layer is higher than the other side thereof; applying a metal layer onto one side of the auxiliary adhesive layer and then heating and pressing the metal layer to bury the auxiliary adhesive layer in one side of the adhesive layer, and then attaching the edge of the metal layer to the adhesive layer and attaching the other portion of the metal layer, excluding the edge thereof, to the auxiliary adhesive layer to provide a carrier for manufacturing a substrate; and forming a build up layer on one side of the metal layer and then removing the edge of the metal layer attached to the adhesive layer to separate the metal layer from the auxiliary adhesive layer, the auxiliary adhesive layer being in a state of attachment to the adhesive layer of the base substrate, wherein the metal layer is separated from the auxiliary adhesive layer by means of warping incurred in the metal layer after removing a border of the metal layer.
