Abstract
A semiconductor package having an improved connection structure and a method for manufacturing the same is described. The semiconductor package includes a substrate having a substrate body, connection pads that are located on one surface of the substrate body, and ball lands that are located on the other surface of the substrate body opposite the one surface. The ball lands are electrically connected to the connection pads. A semiconductor chip having bumps that are formed to correspond to the connection pads is connected to the substrate. An anisotropic conductive member having an insulation element is interposed between the substrate and the semiconductor chip to connect the substrate and the semiconductor chip. Electrically flowable conductive particles within the insulation element flow in the insulation element according to applied electric fields so as to arrange the electrically flowable conductive particles between the connection pads and the bumps.
