Laminated multilayer substrates

摘要

A multilayer package includes a plurality of interconnected large-layer-count (LLC) substrates. The LLC substrates each include conductive pads on the top and bottom surfaces of the substrate, a via in the substrate including conductive material to contact the pads on the top and bottom surfaces, and a post on a pad over the via. The posts of the substrates confront and abut each other, and are electrically bonded together. A non-flowable adhesive film mechanically bonds the LLC substrates, and has an aperture receiving the posts of the substrates.
