- -It relates to fixed abrasive wire saws used for cutting optical substrates, etc., especially fixed abrasive wire saws suitable for precision cutting in hard and brittle materials, especially resin bond wire saws (abrasives are used as resin adhesives)
- the present invention relates to a method for producing a wire saw fixed to a wire and an adhesive composition used in the production method.
- a wire saws used in such cutting processes: free abrasive grains and fixed abrasive grains.
- a wire such as a piano wire as a core material is used by applying an abrasive liquid in which fine abrasive grains such as diamond and silicon carbide are dispersed in an aqueous slurry or oil.
- cutting is performed by running while applying tension to the wire coated with the abrasive liquid.
- abrasive grains interposed in the gap between the wire and the workpiece.
- a fixed abrasive wire saw in which diamond or the like is fixed to a wire has been proposed.
- means for fixing the diamond include a resin bond method and an electrodeposition method.
- Electrodeposition is a method in which diamond is fixed to a piano wire by nickel plating or the like (for example, see Patent Documents 2 and 3).
- This method is a method in which diamond is embedded in the nickel film while nickel is deposited on the surface of the piano wire in the nickel plating solution, and is firmly fixed.
- the strong fixing force is excellent from the point of cutting the ingot,
- the wire diameter gradually increases in the nickel plating process.
- a metal layer made of solder, etc., having a thickness of 5 to 40% of the grain size of diamond (abrasive grain) was formed on the wire, and the diamond was adhered and solidified in the molten state of the metal layer.
- a featured fixed abrasive wire saw is disclosed (for example, see Patent Document 4). In such a method, if the melting point of the solder constituting the metal layer is high, the wire is excessively heated due to melting of the metal layer, the wire is annealed, and there is a high possibility that the tensile strength of the wire is reduced. The selection becomes difficult.
- piano wires and hard steel wires whose hardness and tensile strength are lowered due to annealing of the core wire at a relatively low temperature cannot be used as the core wires. Instead, they are susceptible to repeated bending due to stainless steel or embrittlement. A tungsten wire or the like having the same tensile strength is used.
- the melting point of solder or the like constituting the metal layer is low, the metal layer is melted by heat generated by friction during cutting of the workpiece by the wire saw, and the abrasive grains easily fall off the wire.
- a mixture of a resin adhesive such as a phenol resin and an abrasive such as diamond is coated on a piano wire by using a floating die and heat-treated using an enamel baking furnace (see Patent Document 4). It is something to apply.
- the diamond is fixed by the cured resin (see, for example, Patent Documents 5, 6, and 7).
- an enamel baking furnace a hot air drying method is known (for example, see Patent Documents 8 and 9).
- the resin bond method is suitable for manufacturing a relatively long and inexpensive wire saw.
- the wire saw can be run at a high speed in the cutting of the ingot, and is stable. Cutting can be performed at high speed. Moreover, a thin wafer can be obtained.
- the holding power by the resin is low, diamonds drop off one after another during cutting, and the sharpness and thinning of the wire diameter are likely to occur, and the short life is pointed out as a drawback.
- thermosetting resin adhesive when using a thermosetting resin adhesive, the curing cannot be performed in a short time, and if it is performed at a high temperature, there is a problem with foaming due to decomposition of the curing agent and volatile components accompanying the reaction. For this reason, there has been a problem that the production speed of the wire saw cannot be increased.

- the present invention it is possible to obtain a resin bond wire saw having more stable performance by reheating the wire heated by the infrared heating described above (core wire coated with paste). This reheating is performed for the purpose of removing the thermal strain received by the resin layer and the core wire that repeats expansion and contraction due to the above-mentioned short-time curing by infrared heating.

It was found that production with stable quality was possible with small variations in wafer thickness, deviation in thickness within the wafer, and variation in thickness deviation.
- Table 2 shows cutting (A1) using the resin bond wire saw (a1) obtained in Example 1. Cutting (A2) using the resin bond wire saw (a2) obtained in Example 2 Wire saw by electrodeposition [Abrasive: Nickel-plated diamond grains (particle size 10-20 ⁇ m)], cutting using core diameter 100 ⁇ m) (c) (B) Cutting by free abrasive method (using SiC abrasive # 5000) (C) Shows the arithmetic average surface roughness (Ra) and maximum height (Ry) of the wafer according to JIS B 0601 when a wafer (pitch set to 170 ⁇ m) is cut out from the silicon ingot. The numerical values in Table 2 are average values of measured values at three locations. The cutting conditions are the same as those in FIGS.
- SEM is used to determine the thickness of the damaged layer (work-affected layer) on the wafer surface cut under the same conditions as the cutting conditions in Table 2 by cutting (A1), cutting (A2), cutting (B), and cutting (C).
- Table 3 shows the measurement results using cross-sectional observation.
- Table 4 shows the measurement results of the strength by three-point bending of the wafer cut under the same conditions as the cutting conditions in Table 2 by cutting (A1), cutting (A2), and cutting (B). However, a single crystal silicon ingot was used as the silicon ingot, and the measurement samples were stacked so that the cutting directions crossed alternately. Measurement conditions Sample: 5 wafers overlap bending span length: 30mm Crosshead speed: 5mm / min
- the resin bond wire saw obtained by the present invention can be applied to a TFT substrate, a solar cell substrate, a compound semiconductor substrate, etc. from a single crystal or polycrystalline ingot such as silicon, gallium arsenide, copper / indium / selenium (CIS). It is an indispensable tool for efficiently cutting out the wafer to be used simultaneously. In addition, it is an indispensable tool for efficiently cutting out wafers used for substrates for optical devices, substrates for electronic devices, etc. from magnetic materials, quartz, glass, sapphire, etc. at the same time.
