Abstract
A flip-chip assembly comprises a semiconductor chip, a substrate, a first buffer layer, a second buffer layer and a conductive bump. The semiconductor chip includes a first region and a second region adjacent to the first region. The substrate is disposed under the semiconductor chip. The first buffer layer is disposed between the first region of the semiconductor chip and the substrate. The second buffer layer is disposed between the second region of the semiconductor chip and the substrate. The conductive bump is formed through the second buffer layer and electrically connects the semiconductor chip to the substrate.
