Abstract:
1. A semiconductor device packaged at the wafer level comprising: a semiconductor chip including one or more semiconductor devices formed therein; a plurality of bonding pads being positioned on the semiconductor chip; a protective layer bonded over the semiconductor chip at the plurality of bonding pads or through a plurality of studs positioned over the bonding pads; an insulation material positioned on at least side edges and a lower surface of the semiconductor chip; interconnection bump metallization positioned adjacent one or more side edges of the semiconductor chip; an under bump metallization layer formed between each of the bonding pad pads and the interconnection bump metallization; and a patterned insulation material layer covering selected portions of the bonding pads and supporting the under bump metallization layer, wherein the patterned insulation material layer is formed with a same insulation material as that of the insulation material layer and with a same level as that of the insulation material layer, and comprises one or more openings for formation of one or more remaining walls formed with the insulation material at the level, and the openings being to expose portions of the bonding pads to the interconnection bump metallization, and the patterned insulation material layer assisting formation of the under bump metallization layer and providing structural support, and the remaining walls providing mechanical reinforcement of the under bump metallization layer; and a separate insulation material formed between the insulation material layer and the protective layer, surrounding the semiconductor chip, and surrounding each of the bonding pads and the studs for isolating each of the bonding pads and the studs, for providing electrical isolation of the semiconductor chip, and for avoiding device contamination by particulates generated during device separation.
