<p>PURPOSE:To facilitate the setting of a cutting point by mounting a fine adjustment rotary jig for setting a cutting point on a diamond cutter. CONSTITUTION:A fine adjustment rotary jig 1 is formed of a cylindrical body 3 which has a hole 2, to which a diamond cutter 6 is inserted, at the center, and a fine adjustment rotary jig clamping screw 4 is engaged. The cutter 6 is mounted on the end of the arm 7 of a scriber, the cutter end 8 and a wafer stage 9 are determined in height, and temporarily clamped by a stationary screw 10. The cutter 6 is inserted until the jig 1 is contacted with the upper surface of the arm 7, and fixed by the screw 4 to the cutter 6. Then, the wafer 11 is trially cut to judge the cutting state, and the cutter 6 is finely rotated by a projection 5 to trially cut if improper. When the cutting point is determined, the screw 10 is clamped to secure the cutter 6.</p> |
