The parallelism adjustment mechanism 13 used is, for example, the one shown in FIG. 3, but is not limited thereto. This parallelism adjustment mechanism 13 consists of three square stages 14, 16.
18 are superimposed on each other. The stage 16 is configured such that the angle α with respect to the stage 14 can be arbitrarily changed by rotating the stage 16 with one side aligned with the stage 14 around this side. Further, the stage 18 is configured such that the angle β relative to the stage 16 can be arbitrarily changed by rotating the stage 18 with one side aligned with the stage 16 around this side. These two rotations are sideways to each other,
Thereby, the inclination of the stage 18 can be adjusted freely. The suction nozzle 12 and the contact sensor 11 are mounted on the stage 18

At the time of bonding, the inclination of the suction nozzle 12 is controlled so that a plurality of contact sensors 11 provided at positions corresponding to the height detection projections 23 contact the height detection projections 23 at the same time. Thereby, the parallelism of the suction nozzle 12 with respect to the virtual plane A formed by the tips of the plurality of height detection protrusions 23 is managed. The parallelism with respect to the protruding electrode 22 that is actually involved in bonding is within a very small deviation, for example, about 2 to 3n, since the semiconductor element bonding area is in a narrow range.

The tilt of the semiconductor element is adjusted, for example, as follows. While lowering the suction nozzle holding the semiconductor element,
Change the inclination of the suction nozzle so that the distance between the height detection protrusions and the sensors is the same, so that three or more or all sensors come into contact with the height detection protrusions at the same time, and then Join the elements. In this case, the descending speed of the suction nozzle is kept constant, the inclination is calculated based on the timing of the contact signal of each sensor, and the parallelism is adjusted. Alternatively, once the suction nozzle holding the semiconductor element is lowered, the sensor is brought into contact with the height detection protrusion, and the suction nozzle is tilted so that three or more or all sensors contact the height detection protrusion at the same time. After changing the temperature, the semiconductor elements are bonded. In this case, in order to prevent the position of the sensor in contact with the height detection protrusion from rising or falling, for example, calculate the angles α and β of the parallelism adjustment mechanism 13 shown in FIG. Alternatively, all sensors are brought into contact at the same time, and semiconductor elements are bonded in this state. No matter how the inclination is adjusted, it is sufficient that the virtual plane formed by the tip of the protruding electrode and the bonding surface of the semiconductor element are parallel or nearly parallel at the time of bonding.

Since the height detection protrusion 23 does not open for actual joining,
In other words, it is a dummy bump. Height detection protrusion 23...
is formed, for example, as follows. An electric path is formed on the board using the desired pattern. This pattern is
For example, as shown in FIG. 2, it consists of a bonding electrical path 24 and a branched electrical path 24a. A photoresist is coated on top of these electric circuits to cover the electric circuits, and holes in the photoresist are made by photolithography at the protruding electrode forming portions of the electric circuits, and holes for providing height detection protrusions are also made. Then, using the electric path as an electrode, the holes are filled with a protruding electrode material such as Au by electroplating or the like to form a protruding electrode and a height detection protrusion on the edge of the electric path. The height deviation between the protrusion electrode and the height detection protrusion can be made much smaller than the deviation caused by warpage of the substrate or the like. Therefore, if a height detection protrusion is provided in the same way as a protrusion electrode, and the inclination of the semiconductor element is adjusted using the same height detection protrusion during bonding, the deviation from the virtual plane formed by the tip of the protrusion electrode will be very large. becomes smaller.
