Abstract:
A semiconductor device adapted for mounting on a substrate, the substrate having a chip-mounting region provided with a plurality of solder points, said semiconductor device comprising:a semiconductor chip having a pad-mounting surface provided with a plurality of bonding pads which are disposed on said pad-mounting surface; a plurality of conductive first bumps electrically and respectively connected to and protruding from said bonding pads; a photoresist layer formed on said pad-mounting surface of said semiconductor chip, said photoresist layer being formed with a plurality of access holes registered with and exposing at least a portion of a respective one of said first bumps on said bonding pads; and a plurality of conductive second bumps, each of which has a lower portion filling a respective one of said access holes to electrically connect with and encapsulate said portion of a respective one of said first bumps, and an upper portion extending from said lower portion and protruding from an upper surface of said photoresist layer opposite to said pad-mounting surface.
