The top surface of an insulating substrate is formed with a plurality of electrodes for bump connection, while the undersurface of the insulating substrate is formed with external terminals which are arranged in a matrix. On the insulating substrate is provided a semiconductor chip. The undersurface of the semiconductor chip is formed with bump electrodes. The electrodes for bump connection are electrically connected to the bump electrodes by means of a conductive adhesive. The space between the semiconductor chip and the insulating substrate is filled with a resin which integrates the above two and dissipates heat generated from the semiconductor chip.
