A rotary self-propelled endoscope system includes an insertion section body, an insertion section, a drive unit, a torque detection unit, and a control unit. In a distal end portion of the insertion section body, a rigid distal end portion including an image pickup apparatus is disposed. The insertion section is rotatably fit to the outside of the insertion section body, and includes a rotary tubular member having a helical portion formed by a helical concave-convex portion. The drive unit applies the rotary tubular member with axial and rotational drive force. The torque detection unit detects torque information of the rotary tubular member. On the basis of the torque information detected by the torque detection unit, the control unit compares a present value with a preset limit value for controlling the torque of the rotary tubular member, and controls the drive unit on the basis of the comparison result.

A semiconductor chip is bonded onto a die pad portion of a lead frame including nickel/palladium/gold stacked plate layers. Then, a first bonding procedure is carried out with a metal wire of gold pressed against an electrode pad of the semiconductor chip while applying a load of approximately 60 g and ultrasonic waves with a power of approximately 55 mW by using a bonding tool. Subsequently, a second bonding procedure is carried out with the metal wire pressed against an inner lead portion of the lead frame while applying a load of 150 through 250 g and the ultrasonic waves with a power of 0 through 20 mW. In the second bonding procedure, the wire bonding in conformity with the property of the stacked plate layers can be conducted using a large load and a small ultrasonic power, resulting in attaining firm bonding in a short period of time without causing peeling of the gold plate layer.
