Abstract
A multilayer circuit board is fabricated by: preparing a film comprising a first protective film and a first interlayer adhesive; preparing a first circuit board having a first base and a conductive post protruding therefrom; stacking the first interlayer adhesive and the conductive post together; peeling off the first protective film; preparing a second circuit board including a conductive pad receiving the conductive post; and bonding the first circuit board and the second circuit board through the first interlayer adhesive so that the conductive post and the conductive pad face each other, wherein the first interlayer adhesiveat the top portion of the conductive post is selectively removed while peeling off the first protective film.
