Abstract: PROBLEM TO BE SOLVED: To prevent upside-down mounting at the time of joining a semiconductor carrier to a semiconductor element. SOLUTION: A semiconductor carrier 4 having a nearly square planar shape is provided at its upper left, upper right and lower right positions with marks 12a, 12b and 12c for position recognition, so that, when the carrier 4 is mounted on a printed circuit board or the like, a user mounts the carrier on the board while recognizing the vertical and horizontal positions of the carrier based on the two marks 12a and 12c diagonally located for time saving. Among these recognition marks 12a, 12b and 12c, the mark 12a is made as a circle mark that is different in shape and larger in size from and than the mark 12c. At the time of mounting the carrier 4 on the printed circuit board, even when the user sets the carrier wrongly by 180 degrees in the orientation of the carrier, he can surely find that the carrier is wrongly mounted with 180 degrees of orientation of the carrier.  Thereby upside-down mounting can be avoided.
