Description
Technical field
The invention belongs to silicon crystal cutting technique field more particularly to a kind of aqueous diamond wire silicon chip cutting fluids.
Background technology
With the rapid development of global solar and microelectronic industry, the demand rapid growth to silicon chip.Slice is silicon chip
Processing the first procedure, while be also cause silicon chip stress, surface layer and subsurface stratum damage and chipping one of master operation, and
The performance of cutting liquid is to influence one of the key factor of silicon chip cutting efficiency and quality.
The mainly free mortar cutting suspension of use and the boart boart wire cutting of current silicon chip cutting technique, and diamond
Abrasive wire sawing is a kind of more novel cutting technique, and the diamond being coated with using sand line outer layer is cut with silicon chip friction
It cuts, cutting liquid is no longer needed for suspension and carbonation silicon particle, also no longer needs to have higher viscosity, need not be mixed into the solution
Silicon carbide blade material, cutting speed are 2~3 times of steel wire in mortar cutting technique, and piece rate is also higher than mortar cutting mode, and
Its water power consumed reduces 2/3rds than mortar cutting technique, and the silica flour generated after cutting can all recycle use, because
This will be substantially reduced in the depreciation of specific yield, artificial and energy cost, be energy-saving and environment-friendly.
But due to diamond that in boart boart wire cutting technology, sand line outer layer is coated with and silicon chip friction, and Buddha's warrior attendant
The frictional force that stone sand line generates wants high more than mortar suspension, and when cutting generates moment stronger high temperature, and chip silica flour due to
Granularity is too thin, and specific surface area greatly increases, and which results in the silicon chip surfaces after cutting can difficult cleaning of solid silica fine powder
End, to make product smoothness decline, yield is low, easy warpage.
Invention content
Technical problem to be solved by the present invention lies in:In the technique for avoiding boart boart wire cutting silicon chip, gained silicon chip
There are the solid silicon fine powders for being much not easy to wash on surface, so that it is guaranteed that the surface flatness of silicon chip product.
In order to solve the above technical problems, the technical solution adopted by the present invention is:A kind of aqueous diamond wire silicon chip cutting is provided
Liquid, component include extreme pressure agent, surfactant, antifoaming agent, bleeding agent, SBR emulsion adhesive, deionized water,
Specifically, above-mentioned aqueous diamond wire silicon chip cutting fluid is in parts by weight, including following each component:
Wherein, extreme pressure agent selects synthesizing ester extreme pressure agent, and such as borate ester extreme pressure agent, borate ester extreme pressure agent is as a kind of
Novel Water Soluble EP Additives, anti-extreme pressure ability are much larger than sulphur phosphorous and chlorine lead-type additive, and tasteless, nontoxic,
Corrosion-free to metal with good extreme pressure anti-wear and thermal stability, inhibition is efficient;In addition, strong due to borate oil film
Degree is high, and friction coefficient is low, there is good antifriction antiwear greasy property and sealing material to have under high-temperature and high-pressure conditions good
Compatibility, effect harmless to the human body are a kind of ideal environmental type additives, effectively increase the tribology of cutting liquid
Performance embodies preferable resistance to extreme pressure;
Surfactant is alcohols nonionic surfactant, and structure is RO (C3H6O)a(CH2CH2O)b(C3H6O) cH,
Wherein, R H, allyl, normal-butyl or isobutyl group, a=10~30, b=10~30, c=10~30, the surface
Activating agent promotes the stability of system, and has good greasy property, and high temperature resistant section is wide, viscosity with temperature variation
Small, cooling performance is good, realizes that the silicon chip surface stria after cutting is relatively light or almost without making the consumption line amount of carborundum line also obtain
It is substantially reduced;
Antifoaming agent is silicon class antifoaming agent, such as dimethicone, and the antifoaming agent added in formula, main function is to press down
System generates a large amount of bubbles during hydro-peening, prevents slot phenomenon generation of overflowing, the antifoaming agent is fast with antifoaming speed, foaming capacity is low
The characteristics of;
Bleeding agent is fatty alcohol polyoxyethylene ether or alkyl phenol polyoxyethylene ether, has splendid wetting ability to silicon chip, makes
The maximum effect of sprawling can be played by obtaining the cutting liquid in cutting process;
SBR emulsion adhesive is water soluble latex, preferably SBR l006 types adhesive, this analog assistant is to cutting
The meticulous silica flour of generated granularity has good adhesive effect in the process, which is placed in cutting liquid in advance
In, then by generated partial heat when cutting, taking advantage of a situation can cause these tiny silica flours in system to reunite again, tie
The relatively large particle of grain size is synthesized, these particle parts can smoothly be deposited to cutting liquid bottom, with cutting liquid system shape
Ingredient is from even if the surface that another part has rested on silicon chip product is washed away by that can be easier if subsequent rinse, avoiding
The problem of " silica flour is not easy to be washed away since grain size is meticulous after being attached to silicon chip surface ".
The present invention also provides a kind of preparation methods of above-mentioned aqueous diamond wire silicon chip cutting fluid, are added into deionized water
Surfactant, bleeding agent, antifoaming agent, SBR emulsion adhesive and extreme pressure agent, stir evenly and obtain aqueous Buddha's warrior attendant
Line silicon chip cutting fluid.
The beneficial effects of the present invention are:The aqueous diamond wire silicon chip cutting fluid of the present invention, with it is excellent lubricate, it is cold
But, on the basis of anti-corrosion, antirust, anti-extreme pressure function, cutting process is made by SBR emulsion adhesive a small amount of in formula
In generated tiny silica flour reunite again, be combined into the relatively large particle of grain size, avoid be attached to it is thin on silicon chip surface
Silica flour is not easy the problem of being washed away.And this aqueous diamond wire silicon chip cutting fluid preparation method is simple for process, condition is easily-controllable, at low cost
It is honest and clean, low for equipment requirements, it is suitable for industrialized production.
