Abstract
Semiconductor devices are mounted to a circuit board three-dimensionally by using a tape carrier film with device-connecting electrodes formed on both sides. Bump electrodes are formed on the devices and they are connected individually to these device-connecting electrodes each of which is connected to one of terminal electrodes on the circuit board. The film has throughhole conductors at places to electrically connect bump electrodes on opposite sides of the film.
