Description

The charged sub-element of GHz is with resin combination and the charged sub-element of GHz
Technical field
The present invention relates to the charged sub-element resin combination of GHz.Know clearly it, the present invention relates to possess low dielectric loss angle tangent and be suitable for making circuit board material, particularly GHz electric, electronics be with the circuit board material of usefulness and the resin combination of other electronic component.In addition, the invention still further relates to the electronic component that obtains by this resin combination.
Background technology
In recent years,, expect very much miniaturization, lightweight, the high speed of information communication devices such as PHS, portable phone, seek the electrically insulating material of corresponding low-k with it along with the rapid increase of communication information amount.Particularly the frequency band of the radiowave of using in the mobile communication equipments such as portable mobile communicating such as car phone, digital mobile phone, satellite communications etc. uses the high frequency band of band from MHz to GHz.In addition, because the high frequency band that is called as microwave milli wavestrip is used in the minimizing of spendable wavelength band more and more.In addition, the CPU frequency of computer has also reached GHz band level, and high frequencyization is just in fast development.For the miniaturization that realizes the signal equipment that high frequency band therewith adapts, lightweight, must develop and have the good high frequency transmission characteristic and the electrically insulating material of low dielectric characteristics concurrently.
Physical propertys such as under many situations, the circuit board material of electronics requires that dielectric characteristicies such as specific inductivity and dielectric loss angle tangent are low, thermotolerance and physical strength are good.So-called specific inductivity (∈) is the parameter of the degree of polarization in the expression dielectric medium, and specific inductivity is high more, and the propagation delay of electrical signal is big more.Therefore, in order to improve the velocity of propagation of signal, can carry out high-speed computation, preferred specific inductivity is low.Dielectric loss angle tangent (tan δ) is the parameter of the conversion of signals propagated in the expression dielectric medium loss of signal amount when becoming hot, and dielectric loss angle tangent is low more, and the loss of signal is few more, and the signal transport is just high more.
That is, be called the energy waste in the transmittance process of dielectric loss in the element circuitry, but since this energy waste emit in element circuitry as heat energy, so not preferred.This energy waste is to produce owing to the dipole that produces by dielectric polarization vibrates because of electric field change in low-frequency band, produces by ionic polarization and electronic polarization in high frequency band.The ratio of energy stored is called dielectric loss angle tangent in energy that 1 alternating-electric field was consumed in the dielectric medium in the cycle and the dielectric medium, represents with tan δ.
Owing to tan δ increase along with frequency in high frequency band increases, and cause the thermal value of per unit area to increase, therefore,, must use the little material of tan δ for the dielectric loss that makes insulating material is as much as possible little by the High Density Packaging of electronic component.By the little low medium electrical property high polymer material of working medium loss, suppress the heating that dielectric loss and resistance cause, its result, the flase operation of signal also tails off, and therefore, in the high frequency communications field, expects very much the few material of signal transmission loss (energy waste).
As material, thermosetting resins such as thermoplastic resins such as polyolefine, vinyl chloride resin, fluoro-resin, unsaturated polyester resin, polyimide resin, Resins, epoxy, bismaleimide-triazine resin (BT resin), crosslinkable polyphenylene oxide, curable polyphenylene oxide etc. have been developed usually in order to satisfy following characteristic with electrical characteristic such as electrical insulating property, low-ks.
The boring processibility of veneer sheet, machinability
High heat resistance
The low linear expansion rate
Adaptation or tackiness (Copper Foil adaptation) with metal conductor layer
Physical strength
Film forms ability power
Can in wider scope, set specific inductivity arbitrarily
Insulativity
Weathering resistance
Dielectric characteristics is little to the dependency of temperature, humidity.
But there is problem as described below in above-mentioned resin.
(1) polyolefine
Because polyolefine such as polyethylene, polypropylene have covalent linkage such as C-C key, and do not have big polar group, therefore, its electrical characteristic, particularly insulated electro are resistive good, but have the low shortcoming of thermotolerance.Electrical characteristic (dielectric loss, specific inductivity etc.) when therefore at high temperature using worsen, and are not suitable as the insulating film (layer) of electrical condenser etc.
Polyethylene and polypropylene be as membranaceous formation, and use binding agent lining to be bonded on the electro-conductive material it, but this method complete processing complexity not only, and the problem that exists linings such as being difficult to make the cambial thickness attenuation of film to form.
(2) vinyl chloride resin
The resistive height of the insulated electro of vinyl chloride resin, chemical-resistant, flame retardant resistance are good, but and polyolefine be short of thermotolerance equally, have the big shortcoming of dielectric loss.
(3) pvdf resin, trifluoro-ethylene resin and perfluoro-ethylene resin
These polymkeric substance that contain fluorine atom in the molecular chain, electrical characteristic (low-k, low dielectric loss), thermotolerance, chemical stability are good, but obtaining being shaped and shortcoming is being arranged aspect the shaping processability of classes such as thing or film, the formation ability of filming by heat-treat processing as thermoplastic resin, when making device by this resin, cost is quite high.And, there is the restricted shortcoming of Application Areas because the transparency is low.
(4) Resins, epoxy
The performance that Resins, epoxy is resistive in insulated electro, meet the demands aspect insulation breakdown intensity and the heat resisting temperature.But its permittivity ratio is higher to be more than 3, can not obtain satisfied characteristic.And exist film to form the shortcoming of scarce capacity.Known polyphenylene oxide resin (PPO) and multifunctional cyanate ester resene, further in these resins, add other resin, add radical polymerization initiator, make it carry out the formed curable MODIFIED PP O resin combination of preparatory response, but its low-kization is not able to the level that fully satisfies.And, in order to improve the insufficient Resins, epoxy of thermotolerance, also studying for example combination of phenol linear phenolic resin, vinyl cyanate resin etc., but also having the significantly shortcoming of decline of mechanical characteristic as film.Therefore, in order to keep the above-mentioned problem of improvement on the basis of electrical characteristic, specifically, for improve its hot workability and with the adaptation and the cohesiveness of metallic conductors (layer) such as copper, branching ring-type amorphous fluoropolymer, perfluoro-ethylene monomer and other monomeric multipolymer etc. have been proposed, though electrical characteristic such as its specific inductivity, dielectric loss can satisfy, but because the influence of the methene chain that exists in the high polymer main chain makes its thermotolerance deterioration, so do not obtain yet to good materials of adaptation such as electronics substrates.
(5) polyimide, polyethersulfone, polyphenylene sulfide, polysulfones, thermosetting polyphenylene ether (PPE), polyethylene terephthalate
As the resistive good advanced low-k materials of dielectricity, insulated electro the performance that further requires, owing in the process of making device, must have welding sequence, therefore, at least require it can bear 120 seconds thermotolerance of heating in the time of 260 ℃, and must be chemical stability and wet fastness and all good materials of mechanical characteristics such as thermotolerance, alkali resistance.As everyone knows, the macromolecular material that satisfies these requirements for example has: polyimide, polyethersulfone, polyphenylene sulfide, polysulfones, thermosetting polyphenylene ether (PPE), polyethylene terephthalate etc.But even these resins, its dielectric loss also can increase in the GHz band.
Realize foregoing characteristic in view of independent use resin and have all difficulties, therefore, proposed in resin, to add additive, to improve the electrical properties of resin.For example, open in flat 8-134263 number the spy, proposed: when in synthetic resins, mixing the specific metal silicate fibre-like thing of specified quantitative, specific inductivity and dielectric loss angle tangent can not risen to the degree that obstruction is used in high frequency band, also can improve heat conductivity, thermotolerance and physical strength, and, according to the resin kind of adding, under the situation of the specific inductivity of keeping same degree, dielectric loss angle tangent is significantly descended, therefore, can be highly suitable for as with synthetic resins in the past be suitable for electric, electronic component has the circuit board material of different electric purposes, high frequency circuit board material particularly.
More specifically, open the spy and to have proposed a kind of high-frequency electronic element resin combination in flat 8-134263 number, it is characterized in that, in thermoplastic resin (except the polyamide resin) and/or thermosetting resin (except the resol), will be with general formula aMxOybSiO 2CH 2(at this, a, b and c represent arithmetic number to O.X is that 1 o'clock y represents 1, and x is that 2 o'clock y represent 1 or 3.M represents to be selected from the metallic element more than at least a kind in the group that is made of Mg, Cr, Mn, Fe, Co, Ni, Cu, Zn, Al, Ga, Sr, Y, Zr, Nb, Mo, Pb, Ba, W and Li.) the metal silicate fibre-like material of expression is the fortifying fibre of main component, is that the ratio of benchmark 5~60 weight % is added with the gross weight of above-mentioned resin and above-mentioned fibrous material.
But, to open in the flat 8-134263 communique above-mentioned spy, fortifying fibre is at least more than about 5 weight % with respect to the cooperation ratio of thermoplastic resin or thermosetting resin, and must use this fortifying fibre in a large number.
Summary of the invention
Main purpose of the present invention is that the additive that just can reduce the dielectric loss (or tan δ) in the GHz band is on a small quantity added in exploitation in resin, the electronic component resin combination that can satisfy various requirement neatly is provided.
In addition, other purpose of the present invention is, provide be highly suitable for making have low-k, circuit board material, the particularly circuit board material of GHz band usefulness that the Electrical and Electronic equipment of low dielectric loss angle tangent, high heat resistance, high mechanical strength is used and the resin combination of other electronic component.
To achieve these goals, the present inventor studies without single devotion, found that, in synthetic resins during with a small amount of interpolation nano-scale carbon tube in the specialized range (Na ノ ス ケ one Le カ one ボ Application チ ユ one Block), be suppressed at high frequency band, the particularly rising of GHz band medium loss tangent, and, because energy maintenance heat conductivity, thermotolerance, physical strength, the characteristic that synthetic resins such as specific inductivity have, therefore, the resin combination that contains specific a spot of nano-scale carbon tube can be highly suitable for circuit board material, particularly GHz is with the circuit board material of usefulness.
Because nano-scale carbon tube itself has electroconductibility, therefore, also add 5 weight % opening flat 8-134263 number when above when resembling the spy, the electronic component that is formed by the resin combination that obtains also has electroconductibility.Thereby, think can not resemble the spy open flat 8-134263 number described in the resin combination that the electronic component of high frequency band is used the heavy addition nano-scale carbon tube, and do not attempt reducing the dielectric loss angle tangent of high frequency band so far with nano-scale carbon tube yet.But, research according to the inventor, by using the trace of opening flat 8-134263 number described 5 weight % well below above-mentioned spy to add nano-scale carbon tube, obtained this result outside beyond expectation fully of rising who descends and maybe can suppress dielectric loss angle tangent in GHz band medium loss tangent.

<carbon nanotube 〉
Carbon nanotube is the airtight one-tenth piped hollow carbon material of graphite flake (being the carbon atomic layer or the graphite flake of graphite-structure), and its diameter is a nano level, and wall construction has graphite-structure.In the carbon nanotube, wall construction is to be called single-layer carbon nano-tube with the one piece of airtight one-tenth piped of graphite flake material, and many pieces of airtight respectively one-tenth tubuloses of graphite flake, the material that becomes nested shape are called the multilayer carbon nanotube of nesting structure.Among the present invention, the multilayer carbon nanotube of these single-layer carbon nano-tubes and nesting structure can use.
Operable single-layer carbon nano-tube among the present invention, preferred diameter is that about 0.4~about 10nm, length are those of about 1~about 500 μ m, further preferred diameter is that about 0.7~about 5nm, length are those of about 1~about 100 μ m, and preferred especially diameter is that about 0.7~about 2nm, length are those of about 1~about 20 μ m.
In addition, the multilayer carbon nanotube of operable nesting structure among the present invention, preferred diameter is that about 1~about 100nm, length are those of about 1~about 500 μ m, further preferred diameter is that about 1~about 50nm, length are the material of about 1~about 100 μ m, and preferred especially diameter is that about 1~about 40nm, length are those of about 1~about 20 μ m.
<amorphous nano-scale carbon tube 〉
In addition, above-mentioned amorphous nano-scale carbon tube, as described in WO 00/40509 (No. the 3355442nd, Japanese Patent), be to have the main framing that is made of carbon, diameter is 0.1~1000nm, has the nano-scale carbon tube of amorphous structure, it is characterized in that, form with linearity is in X-ray diffraction method (incident X-rays: CuK α), utilize the interplanar of the carbon net plane (002) of X-ray diffraction method mensuration every (d002) to be More than, particularly More than, diffraction angle (2 θ) is below 25.1 degree, particularly below 24.1 degree, the half breadth of 2 θ band is more than 3.2 degree, particularly more than 7.0 degree.
This amorphous nano-scale carbon tube can obtain by following operation: comprising in the presence of the muriatic at least a catalyzer of metals such as magnesium, iron, cobalt, nickel that pyrolytic resin, for example tetrafluoroethylene, polyvinylidene chloride, polyvinylidene difluoride (PVDF), polyvinyl alcohol that decomposition temperature is 200~900 ℃ etc. excites processing.
As the shape of the pyrolytic resin of starting raw material, can be membranaceous or arbitrary shape such as sheet, Powdered, bulk.For example, when on substrate, obtaining forming the carbon material of membranaceous amorphous nano-scale carbon tube,, excite processing to get final product under suitable condition applying on the substrate or having placed under the pyrolytic state of resin.
But this excites the processing example as follows: for example, in rare gas element, preferably heating under about 450~about 1800 ℃ temperature range and more than the heat decomposition temperature at raw material, under the temperature range of room temperature~about 3000 ℃ and more than the raw material heat decomposition temperature, carry out the processing of plasma treatment etc.
The amorphous nano-scale carbon tube that uses among the present invention is the nano level carbon nanotube with amorphous structure (non-crystal structure), is the hollow linearity, has the highly micropore of control.Its shape mainly is cylinder, rectangular prism etc., and at least one of front end do not have cap (opening) mostly.Front end is when remaining silent state, and it is plane that its shape is mostly.
The external diameter of this amorphous nano-scale carbon tube is usually in the scope of about 1~about 1000nm, preferably in the scope of about 1~about 200nm, more preferably in the scope of about 1~about 100nm.Its long-width ratio (length/diameter of pipe) is more than 2 times, is preferably more than 5 times.
At this, so-called " amorphous structure " is meant not to be the graphite matter structure that continuous carbon-coating constituted by regularly arranged carbon atom, but the carbonaceous structure that is constituted by irregular carbon net plane, a plurality of trickle graphite flakes are being arranged brokenly.The picture that forms from the transmission type microscope of utilizing as the analytical procedure of representative utilizes the nano-scale carbon tube of non-crystal structure of the present invention as can be seen, and the width of the in-plane of carbon net plane is littler than amorphous nano-scale carbon tube diameter.So, amorphous nano-scale carbon tube is not graphite-structure but amorphous structure that a lot of fine graphite flake (carbon wire side) distributes brokenly because its wall portion has, therefore, it is discontinuous in managing longitudinally length range to constitute outermost carbon wire side, forms discontinuous shape.The length that particularly constitutes outermost carbon wire side is lower than 20nm, particularly is lower than 5nm.
Amorphous carbon does not show X-ray diffraction usually, and shows reflection widely.In graphite matter structure, because being regularly, piles up the carbon net plane, therefore, the carbon net plane is (d at interval 002) narrow down, reflect widely to high corner side (2 θ) and move, and narrow down gradually (half breadth of 2 θ band narrows down), can be used as d 002Diffracted ray is observed (when piling up regularly because of the position of graphite relation then
