Abstract

PURPOSE:To make a saw and a cleavage plane parallel by a method wherein the spot of a laser beam is projected on a screen after a saw is placed on a table and the spot of the laser beam applied to the cleavage plane of a crystal which is placed on the table is projected on the screen and is made agree with the previous one by rotating the table. CONSTITUTION:A blade 18 of a saw 19 touches a table 14 on the surface, arms 21, 22 are moved, a mirror 20 adhered to the saw 19 is parallel to it is irradiated by a laser source 23 and a spot A is obtained on a screen 26. Then a single crystal 24 is placed on the table 14, the arms 21, 22 are fixed, the cleavage plane 25 of the crystal 24 is irradiated by the source 23 and a spot A' of reflected light is obtained. The table is rotated until the point A' agrees with the point A. At that time the cleavage plane and the face of the blade 18 are in parallel. The saw 19 descends and cuts the crystal and at each cutting tables 12, 13 are very slightly, so that wafers are cut out. With above configuration cutting is made in parallel with the cleavage plane and the yield of the elements is improved.
