Definitions
- the invention relates to a method for depositing a layer on at least a portion of the surface of a substrate.
- a deposition of a layer on at least a portion of the surface of a substrate by contacting said surface with a liquid phase containing general ⁇ one or more compounds suspended or dissolved in a solvent, or phase of the ground gel type.
- the contacting can be carried out by coating with a stage li ⁇ quide or immersion in a liquid phase of the substrate, or by passing the substrate under a phase curtain li ⁇ quide.
- the layer is then formed by evaporation from soil ⁇ efore the surface of the substrate, evaporation optionally followed by one or more treatments of the forma ⁇ layer, heating type in order to get re ⁇ act / transform / curing compounds or at least superficially modify the layer in formation, and thus obtain the layer with the desired composition and properties.
- Known techniques such as respective ⁇ Anglo-Saxon terms “spin coating” and "dip coating”.
- the control of the thickness, of the homogeneity, and, more generally, of the quality of the layer is delicate because it depends on many parameters. Indeed, especially when one chooses to immerse the substrate in a solution, the thickness of the final layer obtained can be chosen according to the speed with which the substrate is removed from the solution, but the control of the various para ⁇ meters of deposit of this type (rate of withdrawal of the substrate of the solution, temperature conditions ...) is not always sufficient to fully control the characteristics of the layer.
- the object of the present invention is to overcome the disadvantages of the layer deposition techniques mentioned above, by proposing a new deposition method and a new deposition device which may, in particular, make it possible to further improve the control of the properties of the layers thus obtained.
- the invention relates to a process for depositing a layer on at least a portion of the surface of a substrate by immersion at least partially the substrate in a solu ⁇ comprising a solvent and at least one compound for forming the layer, and then drying the substrate which is carried out at least partially in an atmosphere which is isolated from the solution.
- the immersion in the solution and the drying of the substrate take place in the same controlled atmosphere enclosure.
- the compound within the meaning of the invention comprises one or Sev- eral non-volatile compounds which, once dried and EVEN ⁇ tuellement treated, will become the major constituents of the layer, optionally after chemical processing and / or reaction between them.
- the inventors have taken this phenomenon into consideration and have taken care to isolate the substrate during drying from the solution in which it has been immersed beforehand, so as to eliminate this difficult competition to be controlled, or at least to limit to a very short period of time.
- net master ⁇ better drying of the layer by evaporation from the soil ⁇ efore it contains, the vapor pressure of solvent re ⁇ Gnant in the atmosphere where the substrate is located not resulting as the amount of solvent from the forming layer.
- the solution is introduced into the controlled atmosphere chamber to proceed with the immersion of the subs ⁇ trat, and is removed from the chamber with controlled atmosphere during the drying of the substrate .
- the solution is contained in a movable tank to be introduced into the chamber and evacuated therefrom, in particular by a movement ⁇ ment of translation of the vessel relative to the enclosure.
- the substrate is not disposed in a ⁇ surrounded during its immersion and drying and the solution is contained in a vessel provided with one type of closure system cover 1 to prevent evaporation volatile compounds that the solution can comprise between two immersions of substrate.
- a controlled atmosphere is maintained in the enclosure by organizing inside it a flow of gas through.
- the gas may be inert or not, it can have properties change from those of the formation in a layer, for example it may present reducing or oxidizing properties, acid or basic, or be at a temperature ⁇ ticular influencing the composition of the layer formed ⁇ .
- the heating may be moderate, for example from 50 to 100 ° C., to accelerate the evacuation of an organic or aqueous solvent.
- composition of the layer trai ⁇ ted before, during and / or after drying will depend on that of the controlled atmosphere and chemical exchange between neck ⁇ che and atmosphere. These exchanges are governed by bal ⁇ bers condensation / evaporation, existing balances for all known chemical species.
- the subject of the invention is also a device for implementing the method described above and which comprises :
- the means of introduction and evacuation of the solu ⁇ may also comprise:
- a receiving tank mounted the solution by rap ⁇ port to the chamber to get in and out;
- the passage means may include advantageously ⁇ at least one door that is pushed by the vessel to open upon introduction of the vessel in the chamber and which closes automatically during the evacuation of the tank.
- the invention also relates to the application of the method or of the device described above in the forma ⁇ soil layers oxidic gel, oxynitride and / or metal oxycarbide and / or silica, or organic layers or silicified , the layer thicknesses ranging from a few nanometers to several micrometers.
- the substrates to which the invention can be applied can also be very varied: they can be flat or curved substrates, for example made of glass, the layer being deposited on one of the faces or on all the faces of this type of substrates.
- the inventive deposition process went ⁇ larly suitable for covering fully subs ⁇ dimensional tracts.
- the deposition of layers can be used to confer on the substrates different properties, in particular of optical, mechanical or even coating order of products in the food processing or galenic field.
- FIG. 1 represents in section a device according to the invention
- Figures 2a, 2b, 2c, 2d show the steps of depositing a layer on a substrate using the device ⁇ tif according to Figure 1.
- FIG. 1 represents a device according to the invention comprising an enclosure, here an evaporation chamber 1 delimiting a substantially parallelepipedal internal housing.
- the evaporation chamber 1 contains a substrate 2 on which it is desired to deposit a layer, the subs ⁇ trat being fixed to the upper inner wall of said chamber by holding means 3 known per se and therefore will not be detailed here.
- the device comprises means for controlling the atmosphere inside the enclosure.
- the evaporation chamber 1 is traversed by a flow of gas 4 controlled by the control means and conveyed by a duct 41 in the upper part of the chamber 1.
- control means comprise a mass flow controller 5 and a diffusion gate 6.
- the flow of gas 4 is thus controlled in flow rate with the aid of the controller 5, and reaches the chamber via two inputs 11, 11 '. passing through the diffusion grid 6.
- the diffusion grid 6 makes it possible to regularly distribute the flow of gas 4 entering the chamber 1 and to homogenize it so that the flow of gas 4 sweeps the whole chamber 1 while being animated by a moving ⁇ down from the upper wall to the lower part of the chamber 1, where it is discharged by two lateral outlets 12,12 '.
- the gas stream 4 is heated, prior to its in ⁇ tree in the evaporation chamber 1.
- the control means comprise a heating module 7 compre ⁇ ing a series of heating resistors. The heating consists of passing through the pipe 41 carrying the gas 4 by the heating module 7. This heating module 7 can be extinguished, or switched on with a possibility of setting per ⁇ 4 gas to achieve temperatures of, for example ⁇ at 50 to 500 ° C.
- the device according to the invention also comprises means for introducing a solution 13 into the enclosure and evacuating it.
- the introduction means comprise passage means through the wall of the enclosure to allow entry and exit of the solution by these passage means.
- the passage means comprise a hatch 8 closing an opening in the lower wall of the evaporation chamber 1, the hatch 8 opening upwards according to the arrows indicated.
- This trap consists of two parts 81, 82 (which will better using the figures 2a to 2d) which are articulated on two of their opposite edges, so that posi tion ⁇ folded, the two components provide both of them sealing the lower wall of the chamber 1 at this opening.
- the edges of the flaps 81, 82 may be provided with seals on all or part of their periphery.
- the introduction means also comprise a tank 10, containing the solution 13, which is mounted on a platform 9 arranged under the evaporation chamber 1.
- the platform 14, and therefore the tank 10, is movable using means motorized 14, for example here a telescopic jack whose body and stem can be seen.
- Motorized 14 for example here a telescopic jack whose body and stem can be seen.
- Motorcycle ⁇ Rises means 14 used to move the platform 9 and the tank 10 vertically upwardly and downwardly (as indicated FLE ⁇ che f) so that the vessel 10 can be introduced into the evaporation chamber 1 by the hatch 8.
- FIG. 1 represents the stage where the tank 10 is outside the evaporation chamber 1.
- FIGS. 2a to 2d An example of a deposition method according to the invention using this device is detailed hereinafter with reference to FIGS. 2a to 2d.
- the gas stream 4 is an inert gas, of the nitrogen or argon type, introduced under pressure by the inlets 11, 11 'into the evaporation chamber 1.
- the substrate 2 is a glass slide and is intended here to be covered with a sol gel layer S 1 O 2 .
- the holding means 3 of the substrate 2 to the upper internally wall of the enclosure here comprise a connection rod and hooking.
- the platform 9 is disposed under the evaporation chamber 1 and carries the tank 10 containing a solution 13 of compounds (silicon alkoxide, chloridic acid and water) in a solvent, in this case ethanol.
- the first step of the deposition process corresponds to FIG. 2a: the tank 10 and the platform 9 begin an upward vertical translation movement under the control of the motorized means 14 in the direction of the hatch 8 of the evaporation chamber 1, so that the upper edge of the tank 10 pushes the door 8 of the room.
- the hatch 8, under the effect of pressure exerted by the edge of the tank 10 gradually opens into two parts 81,82, letting the platform 9 and the tank 10 in the cham ber ⁇ Evaporation 1.
- the second step corresponds to Figure 2b: the upward movement of the vessel 10 is stopped when the subs- trat 2 disposed directly below the hatch 8 is im ⁇ Merge from the solution 13 to the desired height.
- the two flaps 81,82 of the hatch 8 are then in the maximum open position. Note that the positioning ⁇ re lative and sizing of the substrate 2, the flap 8 and the side walls of the vessel 10 are such that, in this position, the sidewalls of the vessel 10 are contact with the edges of the flaps 81, 82, so as to ensure con ointement a certain tightness of the infé ⁇ lower wall of the chamber 1.
- the third step corresponds to Figure 2c: the associated platform 9 and the tank 10 begin under control of the motor means 14 a translatory motion descen ⁇ ing, so that the substrate 2 out of solution 13, a film of the solution remaining on the surface of the substrate 2 which has been immersed, and that the tank 10 is gradually emerging from the evaporation chamber 1, leaving the shutters 81, 82 to close towards each other under the effect of sim ⁇ ple gravity.
- the fourth step corresponds to FIG. 2d: the hatch 8 has completely closed again, the platform 9 and the associated tank 10 are completely outside the evaporation chamber 1.
- This is the step of drying the film of solution ⁇ tion which has been deposited on the surface of the substrate 2.
- the evaporation of the solvent from the solution film leads to obtaining a thin layer on the surface of the substrate 2, said thin layer having a thickness between 20 and 1000 nm as a function of the rate of removal of the substrate 2 from the solution 13.
- Said thin layer is then made of weakly crosslinked silica.
- this critical step of drying the substrate 2 resulting in the Consti- tution of a solid layer is in the room to atmos phere 1 ⁇ controlled, always swept by the gas stream 4 along with it the solvent vapors in Evaporation course from the film deposited on the substrate 2.
- the vapors of volatile compounds capable of being emitted from the surface of the solution 13 contained in the tank 10 can not modify / disturb the atmosphere of the chamber 1, since the solution 13 is removed from the chamber as soon as the finished substrate 2 is immersed.
- the invention is not limited to the examples vien ⁇ NENT been described, and it encompasses any variant within the scope of the claims. It is also possible, as an alternative to the embodiment shown in figu ⁇ res, that it is the substrate 2 and the enclosure containing it that move relative to the solution 13. It is also possible that the solution 13 remains in the enclosure, but is isolated during drying of the layer by a retractable wall for example, or that the solution 13 and the substrate 2 are in two communicating speakers via a tunnel or an airlock. It is also possi ⁇ ble not to move the vessel 10 by simply drawing the solution 13 in the tank 10 out of the enclosure before drying the substrate 2. It is also possible that the relative movement between the vessel 10 and substrate 2 is made by horizontal translation, or by a combination of translational and rotational movements.
- the method contains only a step of immersing the substrate 2 and drying the substrate 2, the method may also comprise a step of treating the layer formed in the immersion of the substrate in the so lution ⁇ 13 , directly in the enclosure.
- a treatment of the layer during and / or after drying in particular of the type of chemical treatment in vapor phase or high temperature treatment.
- the method according to the invention pro ⁇ pose to heat the deposition chamber by a preheated gas flow, but one can also, alternatively, choose to directly heat the enclosure, which can help reduce the phenomena of internal gas convection in the enclosure.
- the invention is interesting for several reasons: it is particularly suited to the layers of deposits from aqueous solutions, helping to reduce the pheno ⁇ minnow dewetting associated with the high superficial tension aqueous solvents. It also reduces any phase separations at neck deposits ⁇ ches from solutions containing soluble compounds in the solvent but immiscible solvent after the evalu- pore. It also allows to select and control Preci ⁇ cally atmospheric deposition and drying the layer and allows all kinds of processing of the layer.
