Abstract
A method for fixing a semiconductor chip on a circuit board is provided, which includes following steps. The circuit board is provided, which sequentially includes a substrate having a chip connecting portion, at least one metal wire and an insulating layer. An organic insulating material is formed on the insulating layer of the outside edge of the chip connecting portion. An anisotropic conductive film (ACF) is then formed to cover the chip connecting portion and a portion of the organic insulating material. Finally, a semiconductor chip is hot-pressed on the ACF. The organic insulating material formed on the insulating layer is used to prevent the metal wires beneath the insulating layer from occurring of corrosion. A semiconductor chip package structure is also provided.
