COB type IC package to enhanced bondibility of bumps embedded in substrate and method for fabricating the same
Abstract:
An IC package to enhance the bondibility of embedded bumps, primarily includes a substrate having a plurality of bump-accommodating holes, a bumped chip, an encapsulant, and a plurality of external terminals. The substrate further has a plurality of inner pads at one ends of the bump-accommodating holes respectively. The inner pads may be meshed or a soldering layer is disposed thereon for improving bump connection. The chip is attached to the substrate with the bumps aligned and embedded in the corresponding bump-accommodating holes. The encapsulant is at least formed on a lower surface of the substrate to encapsulate the meshes or the soldering layer. By the suspended meshes or/and the soldering layer, the bumps can be easily bonded at lower temperatures to simplify the manufacturing process with shorter electrical conductive paths and thinner package profiles without wire sweeping.
