▎ 摘　　要

NOVELTY - The wire (30) has a coating layer coated with copper. A wire body is provided with a copper alloy, a graphene wire, a diamond, carbon and carbon nanotube. The coating layer is a monolayer. Thickness of the coating layer is 0.35 ~ 200 nm. Thickness of a hetero-metal is 0.1 ~ 0.7 micron. The wire body is coated with a carbon allotrope. A capillary unit (70) is fixed in the wire body. A free air ball (90) is formed in a side end part of the wire body. USE - Bonding wire. ADVANTAGE - The wire improves conductivity process and productivity. The wire reduces manufacturing cost. The wire reduces weight of wire cross sections. The wire ensures better anti-oxidation effect and workability. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a bonding wire.
