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 at locations that are offset from locations of corresponding ones of the solder points on the chip-mounting region; a plurality of conductive inner 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 inner bumps on said bonding pads; and a plurality of conductive bodies, each of which has an extension portion, an anchor portion, and a contact portion on opposite ends of said extension portion, said anchor portion filling a respective one of said access holes and connecting electrically with and encapsulating a respective one of said inner bumps and a respective one of said bonding pads, said contact portion being formed on an upper surface of said photoresist layer opposite to said pad-mounting surface and being disposed at the location corresponding to a respective one of the solder points on the chip-mounting region of the substrate, said extension portion being formed on said upper surface of said photoresist layer and interconnecting said anchor and contact portions.
