Abstract
Connection terminals are provided on the upper surface of a film substrate. Each terminal comprises an electrodeconnecting part and a circular reinforcing part connected to the distal end of the electrode-connecting part. Connection electrodes are provided at a predetermined pitch P on the lower surface of a semiconductor chip. The side length L of the connection electrodes and the pitch P may be reduced to accomplish fine pitching. In this case, the width T of the connection terminal is decreased to some extent, in consideration of the bonding precision. In spite of this, the reinforcing part of each connection terminal hardly peels from the film substrate if it has a diameter that is equal to the length L of the side of the connection electrode.
