PURPOSE:To produce wire bonding wire which allows improved flexural strength and uses less gold material by employing a tubular wire having hollow cross section. CONSTITUTION:Bonding wire 1 is a hollow cylindrical wire which has a hollow part 2. Since a space between a semiconductor element 3 and package wiring 4 is connected by the hollow cylindrical wire 1, strong connection is allowed even with a small quantity of gold material. |
