Abstract:
A method of manufacturing a chip carrier comprising the steps of:forming through holes in a resin sheet; providing connecting wiring for connection to an electrode of a semiconductor device on a first face of an electrical insulating board; forming an external connecting electrode for connection to a connecting electrode of a circuit wiring board; and bonding, to the back face of the electrical insulating board, the resin sheet with through holes already formed, the through holes being in corresponding positions to the external connecting electrodes, the sheet being bonded to the electrical insulating board in such a manner that the external connecting electrodes correspond to the through holes, so that a resin layer is formed, the external connecting electrodes being below the surface of the resin layer and exposed, and a surface of the external connecting electrode being without a bump.
