Abstract
Abstract A semiconductor chip is flip chip bonded on a substrate wherein the semiconductor chip has a first surface on which bumps are provided. An insulating sealing resin is provided in a space defined between the semiconductor chip and the substrate and also around the semiconductor chip. An electrically conductive resin is provided which extends over a least a part of a second surface of the semiconductor chip, a part of the sealing resin and a ground pattern provided over the substrate.
