2. Description of the Related Art FIG. 5 shows a process of a conventional dicing apparatus, in which 21 is a substrate, 22 is a dicing tape, 23 is a high-speed rotating blade, and 24 is ultraviolet rays (irradiation). In FIG. 5, the dicing tape 22 is attached to one surface of the substrate 21 in advance, but the dicing tape 22 has a characteristic that the adhesive force is rapidly reduced when the ultraviolet rays 24 are irradiated. Next, a predetermined position of the substrate 21 is cut by a high-speed rotating blade 23 that rotates at a high speed while cutting the dicing tape 22 while providing an uncut portion. When the cutting is completed, the adhesive force is reduced by irradiating the dicing tape 22 with the ultraviolet rays 24, and then the substrate 21 is peeled off from the dicing tape 22 to complete the dicing process. In this case, since the dicing tape 22 is attached to one surface of the substrate 21, it is possible to prevent the cutting scraps from adhering, but the cutting surfaces and the opposite corners (corner portions) of the other surface are not covered with the cutting scraps. May adhere or remain.

On the other hand, a method has also been proposed in which cutting scraps (cutting scraps) adhering to a cut substrate are directly removed by a brush (see Japanese Patent Laid-Open No. 11-271704). In this method, a cylindrical brush is brought into contact with the sectional surface (cut surface) of the panel to remove dust adhering to the sectional surface during dicing.

In the process of FIG. 5, the dicing tape 22 is preliminarily attached to the substrate 21, and after cutting, the adhesive 24 of the dicing tape 22 is irradiated with ultraviolet rays 24 to reduce the adhesiveness of the substrate. A post-treatment process for peeling 21 is required, and a dedicated facility is required for each process. Further, the cost of the special member such as the dicing tape 22 and the investment in the dedicated equipment have a considerable influence on the product cost, and the adhesive of the dicing tape 22 remains on the substrate 21 depending on the irradiation condition of the ultraviolet rays 24. There is concern that it may be difficult to secure product quality and reliability. In order to solve the above-mentioned problems, when the dicing tape 22 is cut without using it, the substrate 21
Pattern scraps, burrs, etc. remain on both corners of the cutting groove on the back side of
New issues arise in terms of processing and quality. Furthermore, it is difficult to remove the dust remaining at the corners of the substrate, which is the most important, by the method of removing dust by bringing a cylindrical brush into contact with the sectional surface of the panel.

That is, according to the present invention, the jig is used to hold the substrate at the time of cutting, thereby eliminating the need for the dicing tape and the preparatory step and the post-treatment. Since the cutting waste (including the separation scraps and burrs of the pattern) of the surface (when starting from one surface of the substrate and ending at the other surface) may remain without being separated from the substrate, On the other side of the board,
A specific rotating brush is provided so that cutting debris, especially the debris and burrs, can be removed. And, particularly in the present invention, not a cylindrical shape,
Use a disc-shaped rotating brush with two specific inclined surfaces on its outer periphery, not on the cut surface of the substrate or on the other surface, but on the opposite corners (corner portions) on the other surface of the substrate immediately after dicing cutting. By bringing them into contact with each other, it is intended to remove the generated cutting debris, particularly pattern delamination debris and burrs, and prevent damage to the other surface of the substrate.

As described above, according to the first embodiment of the present invention, since the jig 4 for sandwiching and fixing the substrate 1 from both sides is used as the substrate fixing method for cutting (dividing), the dicing tape is unnecessary. Yes, the preparation and post-processing steps such as attachment and peeling can be omitted,
It is possible to reduce dedicated equipment costs and significantly reduce product costs. Further, there is no adhesive residue of the dicing tape on the pattern on the back surface of the substrate, which is advantageous in terms of quality.
Further, by applying the rotary brushes 14 to the opposite corners of the back surface of the substrate immediately after cutting, it is possible to effectively remove pattern peeling debris and burrs on the back surface of the substrate which are generated when the dicing tape is not used.

And burr can be removed at the same time,
Further, since the pattern does not hit the back surface of the substrate, it is possible to prevent the back surface pattern from being scratched.
