摘要:
A semiconductor package includes a semiconductor chip, a protruding pillar electrode provided on the semiconductor chip, and resin covering the semiconductor chip and the pillar electrode. The resin has a concave part and exposes a front edge portion of the pillar electrode from the resin at the bottom face of the concave part. The front edge portion of the pillar electrode is exposed from the concave part of the resin, which makes it possible to suppress increase in the height of the pillar electrode and to form the pillar electrodes having fine patterns or a narrow pitch.

Disclosed are a method of forming a solder on pad on a fine pitch PCB and a method of flip chip bonding a semiconductor device using the same. The method of forming a solder on pad on a fine pitch PCB includes: applying a solder bump maker (SBM) paste with a predetermined thickness to an entire surface of a PCB including a metal pad and a solder mask; heating the SBM paste at a temperature higher than a melting point of solder contained in the SBM paste and then cooling the SBM paste to form a solder on pad; and washing a residual polymer resin and residual solder particles of the SBM paste by using a solvent.

A semiconductor device including a dielectric layer formed on the surface of a post-passivation interconnect (PPI) structures. A polymer layer is formed on the dielectric layer and patterned with an opening to expose a portion of the dielectric layer. The exposed portion of the dielectric layer is then removed to expose a portion of the PPI structure. A solder bump is then formed over and electrically connected to the first portion of the PPI structure.

A method comprises connecting a substrate having a plurality of integrated circuit (IC) dies to a package substrate, so that the package substrate extends beyond at least two edges of the substrate, leaving first and second edge portions of the package substrate having exposed contacts. The first and second edge portions meet at a first corner of the package substrate. At least a first upper die package is placed over the substrate, so that first and second edge portions of the first upper die package extend beyond the at least two edges of the substrate. Pads on the first and second edge portions of the first upper die package are connected to the contacts of the first and second edge portions of the package substrate.
