Abstract: PURPOSE:To dice a semiconductor wafer into individual chips at an improved yield rate by protecting semiconductor devices from cracks or breakage or loss by a method wherein a substrate region corresponding to a scribe line is covered by a metal film, the metal film is then subjected to heat treatment for the formation of an amorphous layer in the substrate region just under the metal film, and the formation of a notch is accomplished from above the amorphous layer by using a notching means for the dicing of the wafer into individual chips. CONSTITUTION:On a GaAs substrate 11, a 50mum-wide metal film layer 17 is patterned for a wafer structure in a region corresponding to a scribe line 12. A heat treatment follows whereby metal atoms present in the metal film layer 17 are diffused into the GaAs substrate 11 for the formation of an amorphous alloy layer 18 in a portion of the substrate 11 just under the metal layer 17. The silicon nitride film 15 formed on the scribe line 12 is subjected to selective removal for the exposure of the alloy layer 18. Formation of a notch 16 is accomplished along the scribe line 12 from above the alloy layer 18. The wafer is then removed from the scriber or dicing saw or the like. Pressure is applied to the wafer from the rear side of the adhesive sheet for the high-yield dicing of the wafer into the multiplicity of MES FET 12 built on the GaAs substrate 11.

Filed: 1984-05-09
Abstract: PURPOSE:To enable accurate control of the distance by which a bonding tool moves, by moving the bonding tool in proportion to the change in rotational angle of a driving motor. CONSTITUTION:A cam follower 4 and a cam follower 5 are disposed so as to sandwich a cam 3 therebetween, and a predetermined pressure is applied to the cam followers 4, 5 by a spring 10.

More specifically, since a pivoting arm 6 and an auxiliary arm 8 are supported at the same pivot point, the center distance L between the cam followers 4, 5 which are the same in terms of the distance to the pivot point is constant at all times. Accordingly, as a driving motor 1 is rotated as shown by the arrow A, a bonding tool 13 is moved as shown by the arrow B, so that the distance by which the tool 13 moves can be made proportional to the rotational angle of the motor 1.
