- a brittle material such as a plate glass, a semiconductor wafer, and a ceramic
- a scribe head and a scribe device provided with the scribe head.
- a rectangular glass used as an electronic component material can be obtained by dividing one large glass plate as a base material and dividing it. At the time of this division, first, an operation of pressing and rolling the cutter wheel tip in one direction with respect to the surface of the base material is performed as a travel start position. Next, the scribing line is similarly formed by changing the rolling direction of the cutter wheel tip in the direction intersecting the previous rolling direction. This forms scribe lines that cross each other (hereinafter referred to as cross scribing). Next, the base material thus cross-scribed in this way is sent to a break machine, where a predetermined pressure is applied to the base material, and a bending moment is applied along the scribe line formed on the base material. The material is cut along the scribe line to obtain the target square glass.

It is applied to the head. That is, as shown in FIG. 12, the chip holder 27 in the scribing head main body 26 A is swung around the axial center of the rotating shaft 2 9 via the rotating shaft 2 9 orthogonal to the surface of the glass plate 90. A position Q 2 that is provided so as to be freely movable and the tip holder 27 has a cutter wheel tip 2 8 in a direction opposite to the traveling direction (arrow S direction in FIG.
- the cutter wheel tip 28 is made to follow the scribe head body 2 6 A while traveling on the scribe head, thereby obtaining the straight running stability of the force wheel tip 28 and distorting the scribe line.
- the cause of this problem is that when the force cutter wheel tip passes the existing scribe line, the force cutter wheel tip is perpendicular to the glass plate 90.
- the necessary force for scribing is that it is scraped off by latent internal stress on both sides of the scribing line.
- the applicant of the present invention has been proposed to solve the above-mentioned problems by providing a main body of a slide head traveling on a brittle material, and an axial center of the pivot shaft via a pivoting axis perpendicular to the brittle material surface.

- the tip holder 32 is controlled so that the swing range is greater than 0 ° and not more than 2 ° during scribing.
- the groove 41 formed on the lower surface of the bearing case 31 is used. It is assumed that it used. That is, when the tip holder 32 is mounted so that the upper end thereof fits in the groove 41 of the bearing case 31 and the tip holder 32 swings to the maximum value of the swing range, the tip holder 32 Make sure that the pair of corners 4 2, 4 5 (4 3, 4 4) located at any one of the four corners at the upper end is in contact with the inner wall surfaces 4 6, 4 7 of the groove 4 1 There is.

- the scribing head proposed by the applicant has a configuration as described above, so that the internal movement of the tip holder near the intersection is ensured while securing the swinging motion of the tip holder which can maintain the straightness of the cutter wheel tip. Since the effect of stress can be minimized, cross fly does not occur even when the pressure applied to the cutter wheel tip is kept constant when performing cross scribing. It is possible to achieve the intended purpose without the scribe line being not formed at the start end.
- the scribing head is provided such that the cutter wheel tip is displaced on the tip holder in the direction opposite to the traveling direction with respect to the axial center position of the rotation axis, and travels with the support shaft side at the head when scribing.
- the cutter wheel tip is pushed upward when crossing the existing scribe line or when it passes through the waviness or warpage of the glass or the unevenness of the glass surface, and the tip holder rotates around the spindle. Then it tries to float up from the glass surface.

- the depth reached by the vertical crack the edge load that can control the depth reached by the tip of the vertical crack (hereinafter referred to as the depth reached by the vertical crack). That is, when the load on the cutting edge is increased, the cutting edge of the cutter wheel tip bites into the surface of the glass, and the energy for generating the vertical crack increases, so the depth of the vertical crack becomes deeper.
- the load on the cutting edge exceeds a certain size, so-called deep vertical cracks can be obtained, but at the same time internal strain accumulated near the surface of the glass becomes saturated and the growth direction of the vertical cracks is completely different.
- a so-called horizontal crack occurs in the direction of the heading crack. Such horizontal cracks are desirable And cause a large amount of swarf to be generated.

That is, as can be seen from the graph shown in FIG. 6, the depth reached by the vertical crack is such that there is a region (region A) where the depth gradually increases as the load on the cutting edge increases. There is a region (region B) that increases rapidly with the increase in edge load, and there is a region (region C) in which there is almost no increase even when the edge load increases. And in this C area, horizontal cracks not seen in the A area and B area are added significantly.

- the traveling direction of the scribe head was as in the prior art, that is, the direction of the arrow mark S in FIG. 4 and others were performed under the same conditions as the embodiment of the present invention.
- the direction of the tip holder 4 was reversed from that in the above embodiment so that the rotary shaft 13 of the cutter wheel tip 5 is positioned on the rear side of the rotary shaft 7 when traveling.
- Comparative example 1 1 0 ⁇ ⁇ ! ⁇ 1 2 0 ⁇ m
- a scribing method of the present invention is a process of forming a scribe line on a flat panel display (FPD) to which a brittle material such as a display is bonded, a transmissive projector substrate, a reflective projector substrate or the like. The scribe head is effectively applied.
- the scribing method and scribing head and scribing apparatus according to the present invention can obtain vertical cracks which form scribing lines much deeper than in the prior art, and in particular, scribing lines intersecting each other are formed on a brittle material substrate. It is preferable that the brittle material substrate can be easily cut along the scribe line in the dividing step after the cross scribing. In addition, it is possible to eliminate the occurrence of defective products, which is also beneficial in terms of dramatically improving production efficiency compared to conventional products.
- the technique for forming a scribe line according to the present invention can be applied not only to a glass plate but also to a mother substrate such as a liquid crystal display panel, PDP, FPD, transmission type projector substrate, reflection type projector substrate or the like. .
