20090140426 | FLIP CHIP PACKAGE AND METHOD FOR MANUFACTURING THE SAME - A flip chip package includes a substrate and a semiconductor chip. The substrate includes a substrate body, a metal wiring having a terminal part some of which is disposed in the substrate body, a solder resist pattern formed on the substrate body with an opening for exposing the terminal part, and an organic anti-oxidation layer for covering the terminal part. The semiconductor chip has a bump formed through (e.g., penetrates) the organic anti-oxidation layer and is electrically connected to the terminal part. The present invention prevents oxidation of the terminal part and allows easy coupling of a bump of a semiconductor chip and the terminal part of the substrate, since an anti-oxidation layer including an organic matter is formed over a surface of a terminal part including copper which is easily oxidized. | 06-04-2009 |
