Definitions
- the technical field of the invention is that of processes for the preparation on a micrometric scale of multilayer composite materials consisting of stacks of conductive and insulating layers.
- Multilayer composites are known to have attractive microwave properties.
- finely laminated magnetic / insulating multilayer stacks make it possible to produce high-performance microwave components, such as, for example, tunable filters (see document [1]).
- These composites also make it possible to produce inductive cores having applications in the radio frequency domain (see documents [2] and [3]).
- the optimal thicknesses of the ferromagnetic layers are generally in the range between 0.1 and 3 ⁇ m.
- the ferromagnetic layers are generally obtained by vacuum deposition. It is thus possible to produce ferromagnetic / insulating alternations.
- the total thickness of the multilayer is increased, the internal stresses in the layers are added and can cause ruptures of layers and detachments, which are harmful to applications.
- the object of 'the invention is to allow the realization of multi-layer composite consisting of a stack of layers of ferromagnetic material and finely divided insulating material, the thickness of insulating layers being located in a desired range and the layers of multilayer being free of stresses applied by the substrate.
- a process for producing a composite multilayer comprising a stack of layers of electrically conductive material alternating with layers of electrically insulating material, said process being characterized in that it comprises the following steps : a) deposition of electrically conductive material, in the form of a layer, on a peelable surface of a deposition support, b) adhesion, by coating of the glue of electrically insulating material, of a layer of said electrically conductive material deposited on a peelable surface of a depositing support, on a receiving support, c) separation, by peeling, of the depositing support and the layer of electrically conductive material adhering to the receiving support, this separation providing a elementary stack comprising a layer of glue and a layer of electrically conductive material, d) adhesion, by coating of the glue of electrically insulating material, of another layer of said electrically conductive material deposited on a peelable surface of a deposition support, on the elementary stack obtained previously
- the deposition support is composed of a polymer film and one or more transfer layers, that is to say one or more layers allowing the transfer.
- the receiving support can be a film or an object on which the elementary stack is pressed. According to a particular embodiment, the receiving support is moved by a rotational movement.
- the separation steps are carried out during winding after a partial winding of the elementary stack around the support.
- the receiving support is a cylindrical support, for example a roller.
- the steps of deposition, adhesion and separation are carried out continuously.
- the deposition of the electrically conductive material is carried out by magnetron-assisted sputtering.
- the electrically conductive material is a ferromagnetic material.
- it is a soft amorphous or nanocrystallized ferromagnetic material.
- the ferromagnetic material can for example be based on CoFeSiB, CoNbZr or FeNi.
- the electrically conductive material is chosen from an amorphous ferromagnetic alloy based on cobalt, iron or nickel.
- the layers of electrically conductive material can be composed of materials having the same chemical compositions and / or the same electromagnetic properties.
- the layers of electrically conductive material can be composed of materials having different chemical compositions and / or electromagnetic properties.
- the layer of electrically conductive material has a thickness of between 0.1 and 10 times the skin thickness of the material. It is recalled that the skin thickness corresponds to the zone in which an electromagnetic wave can propagate by penetrating into a conductor. More specifically, skin thickness is defined as the depth at which the amplitude of a wave incident electromagnetic is divided by e 1 .
- the adhesive layer is deposited on the peelable surface of a deposition support, on the receiving support or on both.
- the adhesive is preferably activatable by pressure or temperature.
- step d) of separating the deposition support from the layer of electrically conductive material can be done continuously, after the contacting step, if the adhesive used is quick setting. If the adhesive is slow setting, it is necessary to observe a crosslinking step of said adhesive before proceeding with the release of the support film.
- the adhesive (s) used are preferably of the high tack type, activated hot or cold, or of the quick setting type.
- the advantage of these adhesives is that they can be coated in very thin thicknesses ( ⁇ 1 ⁇ m) while retaining the covering character and the properties required for immediate bonding by pressure. This glue thickness can be adjusted up to a few micrometers to improve the quality of the coating.
- the adhesive is chosen from the group comprising adhesives of the polyester, polyurethane, epoxy, phenoxy or cyanoacrylate type.
- the method further comprises, before the adhesion steps, a step of depositing a layer of electrically insulating material on the layer of material electrically conductive, prior to coating the adhesive.
- the method further comprises, after step e), a step of depositing a layer of an electrically insulating material on the layer of electrically conductive material of the elementary stack.
- a layer of electrically insulating material is deposited on the surface of the receiving support. This embodiment is particularly advantageous when the receiving support is a stack of layers of electrically insulating material and layers of electrically conductive material.
- a layer of electrically insulating material is deposited on the peelable surface of the deposition support, prior to the deposition of the layer of electrically conductive material carried out in step a).
- an electrically insulating material makes it possible to perfect the uniformity of the layers of adhesive, the electrical insulation of the elements of electrically conductive material and the parallelism of the stacks, or even to give an internal geometry to the composite material.
- This electrically insulating material acts as a fixed space and as an insulator between the layers of electrically conductive material during the structuring of the multilayer. It preferably has a sufficient covering character and good chemical resistance to the adhesives solvents.
- this electrically insulating material is combined with a wetting agent which makes it possible to facilitate the coating of the adhesive and to avoid the appearance of defects in the adhesive layer during the evaporation of the solvents.
- the electrically insulating material is chosen from an inorganic, organic or mixed varnish, a compound obtained by a sol gel type process, and a primer reactive with the layer of electrically conductive material.
- the adhesive layer has a thickness of between 0.3 and 10 ⁇ m. These thicknesses are adapted according to the type of adhesive used so as to give the composite multilayer the best mechanical strength.
- the layer of electrically insulating material has a thickness of between 0.1 and 20 ⁇ m.
- the application of the layer of adhesive and / or of electrically insulating material is carried out by coating in the unrolled manner smoothly or according to a pattern.
- Smooth applicator rollers can be used for coating glue or electrically insulating material in continuous thickness and rollers comprising profiles or patterns for depositing glue or electrically insulating material in discontinuous form.
- the presence of patterns in the layer of glue or material electrically insulation can allow contacts between layers of electrically conductive material.
- hard varnishes preferably inorganic
- These hard varnishes can be deposited in the form of continuous thin films or in a pattern.
- the mechanical properties of these varnishes can allow, by their hardness, to impose a geometry between the layers of electrically conductive materials.
- flexible varnishes preferably organic, are used.
- the layers of electrically insulating material are composed of materials having the same chemical compositions.
- the layers of electrically insulating material or not are composed of materials having different chemical compositions.
- the adhesion steps are carried out by a technique chosen from calendering, plating or co-winding under tension.
- the plating is carried out by joint passage under tension on idler rollers.
- the advantages of this method compared to the methods of the prior art are numerous.
- the method according to the invention makes it possible in particular to rapidly obtain a continuous and modular composite multilayer.
- the area of the composite multilayer obtained is limited only by the size of the deposition supports and not by the process itself.
- composite multilayers having a three-dimensional architecture can be obtained by adjusting the thickness of the layers of electrically insulating material and their periodicity. It is thus possible to obtain a composite multilayer which remains flexible while comprising a large number of layers using a varnish with low rigidity.
- the method according to the invention makes it possible to obtain high metal charge rates while preserving the dielectric nature of the composite multilayer.
- a large composite stack can be produced containing successive layers of a micrometer of insulation (varnish and glue) and metal.
- the ratio of the active material (metal) to the total volume of the multilayer is greatly increased.
- the layers of electrically conductive materials deposited under vacuum on a flexible support are often constrained by this deposit support.
- the method according to the invention proposes to remedy this drawback, by distinguishing the deposition support and the support used in the multilayer (receiving support), and by revealing how to pass from one to the other. It is thus possible to relax the constraint that the deposition support imposes on the electrically conductive material, which has an influence on the magnetic properties of magnetostrictive materials.
- Composite multilayers are then obtained having the thicknesses of insulation in the desired range and the layers of which are free of stresses.
- the invention also relates to a radio inductor characterized in that it comprises a composite multilayer produced according to the production method seen above.
- the composite multilayer of this radio inductor has layers of electrically conductive material which have a thickness of between 0.1 and 3 ⁇ m and layers of electrically insulating material and of glue which have a thickness of between 0.5 and 50 ⁇ m .
- FIG. 1 represents the steps for producing a composite multilayer according to the invention
- FIG. 2 illustrates a composite multilayer according to the invention
- FIG. 3 is a particular case of the invention where the layer of electrically insulating material is applied in a pattern
- FIG. 4 represents a three-dimensional composite multilayer according to the invention
- FIG. 5 illustrates a step of producing a cylindrical composite according to the invention.
- steps A to F of FIG. 1 The different steps of the process for producing a multilayer composite material according to the invention are described in steps A to F of FIG. 1.
- a layer of material amorphous ferromagnetic 1 is deposited on a support.
- This support is composed of an organic polymer film 2 on which a transfer layer 3 has previously been deposited.
- a protective layer can optionally be deposited on the transfer layer 3 to protect said transfer layer against possible phenomena of alterations in the case of deposits made under vacuum. This layer will thus be part of the final stack.
- This protective layer can therefore in itself be made of material electrically insulator and constitute a hard insulator, preventing electrical contacts in the final composite.
- the assembly consisting of layers 2 and 3 forms a peelable film.
- the deposition of the layer of amorphous ferromagnetic material 1 can, for example, be carried out by magnetron-assisted sputtering.
- a layer of electrically insulating material 4 is deposited on the layer of amorphous ferromagnetic material 1.
- a layer of adhesive 5 is then deposited, necessary when the composite is structured, on the layer of electrically insulating material 4 and a second layer of adhesive 5 is deposited on the receiving support 6 onto which it is envisaged to transfer the electrically insulating deposit 4.
- the receiving support 6 can be a flexible film reinforcement with a thickness of between 1.5 and 100 ⁇ m which will, for example, be made of polyester or polyimide or any other polymer or flexible material.
- the glued receiving substrate 6.5 and the glued transferable film 2,3,4,1,5 are then placed opposite.
- a composite is then obtained comprising an additional deposition layer separated from the previous one by the adhesive layer or layers.
- the receiving substrate can be a film or an object on which the film is pressed.
- a tensile force 11 is exerted on the multilayer consisting of the layers 2,3,4,1,5,6 on either side of the transfer layer 3 (see step E of FIG. 1).
- the ferromagnetic layer 1 is separated from its deposition substrate 2,3.
- a layer of glue 5 see step F of FIG.
- step 1 1) is deposited on the multilayer 4 , 1,5,6 containing the first ferromagnetic layer transferred and the production process is then resumed at the coating step, the support 5, 6 then being replaced by the multilayer 4,1,5,6. It is possible to deposit this layer of adhesive 5 on the new film to be transferred (as in the case of step B in FIG. 1) or on both sides. Note that the insulation layers and the ferromagnetic layers are not necessarily always the same: in fact, it is easy to produce multilayer composites of mixed composition, as long at the ferromagnetic layer deposited only
- the composite multilayer can be structured by the successive stacking, by gluing on the unwinding, of continuously bonded and peeled layers of their deposition supports on which they were first deposited.
- a multilayer 20 is obtained in the form of a set of plates 4, 1, 5, 1 on a receiving support 6 as shown in FIG. 2.
- the ferromagnetic-insulating multilayer stack has thicknesses of electrically insulating material between 0.5 and 50 ⁇ m and thicknesses of ferromagnetic layers between 0.1 and 3 ⁇ m.
- the receptor support 6, useful during the deposition phases or during the preparation of the composite multilayer can be kept or eliminated at any time during the operations for implementing the final product, depending on its use.
- the latter can be cut or grooved mechanically, chemically, or thermally and undergo various thermomagnetic and protective treatments.
- thermomagnetically anneal the multilayer in order to optimize the magnetic properties of the electrically conductive material (s).
- This annealing could also have been carried out on the deposition support comprising the layers of electrically conductive and insulating material before transfer to the receiving support.
- the final product obtained can also be in the form of a multilayer film wound around a central mandrel. In this case, the multilayer film will be wound under tension during its production, the pressure that the layers exert on each other sufficient to ensure the cohesion of the composite multilayer.
- the deposition support consisting of a polymer layer 2 and a transfer layer 3, receives a layer of electrically conductive material 1.
- a layer of varnish 7 is then deposited therein according to a predefined pattern.
- the glue 8 is selectively deposited so that the areas not covered with varnish are not covered by the glue.
- the assembly is carried out taking care to position the insulating patterns so that the desired periodicity of the contacts is obtained.
- the distances between the contact points of the ferromagnetic layers can for example be fixed at a fraction of the wavelength of the incident field.
- the stacks can be wound around a cylindrical or non-cylindrical receiving support, moved by a rotational movement, for example around a roller or a torus.
- the receiving support 6 of the transferred 2,3,4,1,5 films can be directly a torus 9 driven by a rotational movement on which the composite film is pressed and stripped of the deposition support 2,3 after a partial winding as illustrated in FIG. 5.
- a stack is made on a deposition support according to the method for producing a composite multilayer according to the invention, then a layer of adhesive is deposited on the layer of material electrically conductive of the stack 2,3,4,1,5.
- the stack obtained is then brought into contact with a torus which here acts as a receptor support. This torus is rotated.
- the deposition support 2,3 is separated from the rest of the stack after the latter has been partially wound around the torus.
- the uses of the composite multilayer once produced are multiple. It can be integrated into high frequency devices (for example, in a microstrip line) for electronic applications such as magnetic switches, filters ... It can be integrated into inductive devices for radio applications or be applied on sensitive components to protect them from pulses or electromagnetic interference.
- the deposition support supplied by MALAHIDE®, is composed of a film of polyethylene terephthalate (PET) with a thickness of 50 ⁇ m on which are successively deposited a transfer layer, a layer of varnish and a protective aluminum layer. Then, a 0.8 ⁇ m thickness of Co 8 8Nb7Zr 5 alloy (in atomic percentage (at%)) is deposited by magnetron sputtering on the aluminum layer. On the ferromagnetic film, a layer of 0.3 ⁇ m of protective silica obtained from a colloidal silica gel LUDOX HS40 ® is then deposited, by coating on the unwound.
- PET polyethylene terephthalate
- a 0.8 ⁇ m thickness of Co 8 8Nb7Zr 5 alloy in atomic percentage (at%)
- a layer of 0.3 ⁇ m of protective silica obtained from a colloidal silica gel LUDOX HS40 ® is then deposited, by coating on the unwound
- a layer of 1 ⁇ m of E505 glue supplied by Epotecny ® is deposited, still by uncoating.
- the whole is assembled on a receiving support and the transfer layer and the PET layer are removed, once the crosslinking of the adhesive is complete.
- These steps are repeated 25 times until a lamellar composite with a thickness of 50 ⁇ m is obtained, with a volume charge rate of magnetic material of 40%.
- the composite multilayer obtained, once cut to suitable dimensions, can be inserted into a micro-ribbon line to obtain a tunable frequency filter.
- the deposition support supplied by MALAHIDE®, is composed of a film of polyethylene terephthalate (PET) with a thickness of 50 ⁇ m on which are successively deposited a transfer layer, a layer of varnish and then a protective aluminum layer.
- PET polyethylene terephthalate
- a 2 ⁇ m thickness of Co 88 Nb 7 Zr 5 alloy (in at%) is then deposited, by magnetron spraying, on the aluminum layer.
- a layer of 1 ⁇ m of glue E505 supplied by Epotecny® is then deposited, by coating in place, and the stack thus formed is wound around a torus by continuously peeling off the deposition substrate after three quarters of a turn.
- the ferromagnetic volume charge rate of this torus is 66%.
- the deposition support supplied by MALAHIDE®, is composed of a layer of PET of thickness 50 ⁇ m on which are successively deposited a transfer layer, a layer of varnish and a layer of aluminum. protective. A thickness of 2 ⁇ m of alloy Co 88 b 7 Zr 5 is then deposited in the unwinding by magnetron spraying.
