Abstract: PURPOSE:To prevent faults of semiconductor device due to contact with conductor wires, by pushing up conductor wires by projections, which can be moved up and down, forming loops, lowering the projections when a connected semiconductor chip and a terminal conductor are sent, thereby avoiding damage of the conductor wires. CONSTITUTION:By using an ultrasonic wave bonding apparatus, electordes 21 of a semiconductor chip 2 and outer lead parts 12 of a lead frame are connected with Al conductor wires 5. At this time, each Al conductor wire 5 is lifted by a projection 31 on the upper surface of a work supporting body 3 and a loop is formed. Thus, the contact of the conductor wire to the edge part of the chip or to the other electrode is prevented. Thereafter, the work supporting body 3 is lowered in the direction of an arrow 42. Thus the conductor wire 5 is not damaged by the projection 31 when the lead frame 1 is moved in the right and left directions. The loop, which is formed by the wire connecting the semiconductor chip and a terminal, is not contacted with the edge part of the chip, and the poor connection due to said contact is avoided.
