Abstract:
A chip carrier comprising:an electrical insulating board;a connecting wiring for connection to an electrode of a semiconductor device which is provided on a first face of the electrical insulating board; andan external connecting electrode for connection to a connecting electrode of a circuit wiring board,wherein the external connecting electrode is formed by a bump made of a conductor, a resin layer is previously formed and hardened so as to cover a side of the bump before mounting of the chip carrier on a circuit wiring board, the resin layer having a thickness sufficiently small so that the resin layer does not contact a circuit wiring board when the chip carrier is mounted on the circuit wiring board via the bump, and the bump is covered with the resin layer to a level of 20% or more with respect to a height thereof from the chip carrier.
