Abstract: PROBLEM TO BE SOLVED: To raise a frictional force in the horizontal direction, which works on suction heads and the rear of a semiconductor element, and to prevent the generation of a mounting positional deviation of the semiconductor element from a wiring board at the time of mounting of the element on the wiring board by a method, wherein the rear of the element is roughened by machining to the extend such that a suction force between the rear of the element and the suction heads is not reduced. SOLUTION: When a semiconductor element 9 is sucked by suction heads 2, recesses and projections are made to form in and on the rear of the element 9 to roughen the rear of the element 9 by machining so that a frictional force F2, which works on the heads 2 and the rear of the element 9, is reduced to an external force F, which is accompanied by the high-speed movement of the heads 2, and so that the frictional force F2 becomes larger than a frictional force F1, which works on conventional suction heads 2 and the rear of a conventional semiconductor element.  In this way, since the frictional force is increased to the extent that the air does not leak from between the heads 2 and the element 9, the element 9 is sucked by the heads 2, and a suction positional deviation of the element 9 from the heads 2 at the time of the high-speed movement of the heads 2 can be reduced, the positional deviation of bump electrodes on the element 9 from conductor wirings on a wiring board can be reduced.

Prior to this measurement, only inside measurement is performed so that inside measurement data of a number corresponding to the time ratio or a multiple thereof are taken into a memory for inside measurement. Once this measurement is started, a part of the inside measurement data(10 for example) are updated in the memory for inside measurement at each cycle of measurement and a moving mean is obtained. With this moving mean, the mean value of outside measurement values of 100 for example is calibrated.
