Abstract:
1. A method for fabricating a multilayer circuit board, comprising: preparing a first film including a first protective film and a first interlayer adhesive stacked together; preparing a first circuit board including a first base and a conductive post protruding from said first base; stacking said first film and said first circuit board together so that said first interlayer adhesive and a top portion of said conductive post are brought into contact with each other; peeling off said first protective film from said first interlayer adhesive while selectively removing said first interlayer adhesive at said top portion of said conductive post with said first protective film to expose said top portion; preparing a second circuit board including a conductive pad; and stacking and bonding said first circuit board and said second circuit board together through said first interlayer adhesive so that the exposed portion of said conductive post and said conductive pad are bonded together.
