A semiconductor manufacturing apparatus includes a flux container defining an accommodation space, the accommodation space configured to accommodate flux, a head tool configured to pick up and position a semiconductor device, semiconductor device including a connection terminal, and a vibration generator configured to apply vibrations to the flux container.

A wire bonding apparatus may include a wire supply portion configured to supply a conductive wire, a capillary configured to draw out the conductive wire supplied from the wire supply portion, and a wire holder disposed between the capillary and the wire supply portion. The wire holder has a first clamp and a second clamp that are spaced apart from each other and are configured to clamp the conductive wire. Each of the first clamp and the second clamp has a polygonal column shaped support body having with a plurality of contact surfaces along a circumference of each of the first clamp and the second clamp, and the polygonal column shaped support body is configured to rotate in a circumferential direction about a central axis of the polygonal column shaped support body.
