A semiconductor chip is applied onto the semiconductor chip-mounting region. The semiconductor chip in its electrode pad is connected by bonding to the TAB tape in its inner lead. The bonded connection is subjected to plastic molding. Solder balls are provided on the backside of the TAB tape in its portion corresponding to the semiconductor chip-mounting portion. Thereafter, the package portion is cut off at the cutting position in the linking portion of the slits. By virtue of the above constitution, highly reliable BGA type semiconductor devices can be produced while reducing the thickness and reducing the size.
