Abstract:
1. A bonding apparatus comprising: a bonding processor for executing a bonding process on a bonding subject using a bonding tool; a plasma capillary having a high-frequency coil wound on a tip end portion thereof; an inductively coupled microplasma generator including the plasma capillary and for performing a surface treatment on the bonding subject by ejecting gas being a plasma in an interior of the plasma capillary by supply of electric power to the high-frequency coil of the plasma capillary, from an opening at a tip end portion of the plasma capillary onto the bonding subject; a position changing unit for changing positions a tip of a thin wire being made of a prescribed material inserted the interior of the plasma capillary between a surface removal position being outside of a plasma region and a surface deposition position being inside of the plasma region in the interior of the plasma capillary; and a controller for depositing the prescribed material on the bonding subject to move positions of the tip of the thin wire to the surface deposition position in the inductively coupled microplasma generator by controlling the position changing unit after removing foreign matter or contaminants of a surface on the bonding subject to move positions of the tip of the thin wire to the surface removal position in the inductively coupled microplasma generator by controlling the position changing unit.
