Abstract
A semiconductor device comprises an insulating substrate such as a film carrier having wiring patterns formed thereon, lead electrodes connected to the wiring patterns, and a semiconductor chip bonded to the lead electrodes. The surface of the lead electrodes, to which the semiconductor chip is bonded, is smooth as compared with that of the wiring patterns, thereby ensuring accurate operation of the semiconductor device.
