Abstract
A semiconductor element-housing package, comprising an insulating substrate composed of a plurality of laminated insulating layers and having a mounting portion for mounting a semiconductor element, in the center of a top surface thereof; a ground bonding pad and a power-supply bonding pad formed on the top surface of the insulating substrate, at the periphery of the semiconductor element-mounting portion, to which a ground electrode and a power-supply electrode of the semiconductor element are connected; and a pair of capacitor-connecting pads, formed on the underside of the insulating substrate, one of which is connected to the ground bonding pad, the other of which is connected to the power-supply bonding pad, and to both of which electrodes of a chip capacitor are connected, characterized by having a ground plane and a power-supply plane sandwiching at least one of the insulating layers buried opposing each other within the insulating substrate, and having electrical connections from the ground plane and the power-supply plane to the ground bonding pad and the power-supply bonding pad, respectively, at the periphery of the semiconductor element-mounting portion of the insulating substrate, to thereby downsize the package and to produce a satisfactory, noise-reducing effect.
