Abstract
A method for manufacturing a circuit board includes: preparing a first substrate and a second substrate, wherein: the first substrate comprises a convex post member formed at a top surface of the first substrate, and the second substrate including a first surface and a second surface opposite to the first surface, and comprising: a first metal layer formed on at least the first surface, and an opening through which a top surface of the post member is uncovered in a plan view; bonding at least a portion of a top surface of the first substrate excluding the post member and the second surface of the second substrate so that the top surface of the post member is uncovered through the opening; and forming a circuit pattern by removing a first portion of the first metal layer.
