Definitions
- the invention relates to the production of a thin fragmented layer of material on a support. It applies in particular to obtaining a catalyst for the production of carbon nanotubes or nanofibers.
- the catalyst is one of the important elements allowing the growth of carbon nanotubes as well for the growth methods in
- CVD chemical vapor deposition
- the qualities sought for the catalyst there is of course its effectiveness: the problems of technological integration make that one seeks to obtain catalysts which allow growth reactions at the lowest possible temperatures.
- a catalyst that can be integrated into microelectronic devices. For this purpose, thin layers of nickel, cobalt or iron are used.
- the plasma is either a relatively high temperature nitrogen plasma, from 600 ° C to 900 ° C (see the publication of Gao JS, Materials Science and Engineering 2003, A352, p. 308-313) or an ammonia plama at 390 ° C, (see for example the publication of Choi JH, Thin Solid Films 2003, 435, p. 318-323).
- the objective in the latter case, is to etch the catalyst to control the density of particles.
- the particles obtained are relatively large (between 60 and 100 nm in diameter) except for deposited layer thicknesses of the order of nm. It can therefore be seen that the 4 parameters mentioned above are not satisfied and that the only parameter making it possible to vary the diameter of the particles obtained is the thickness of the deposited layer.
- the object of the invention is a process for producing a divided material making it possible to obtain a large state of division.
- This state of division is controllable by means of another parameter than the thickness of the deposited layer of this material.
- the invention relates firstly to a method comprising a step of depositing in a discontinuous form a thin layer of a first material on one face of a support and then a step of placing in drops, by a heat treatment or by treatment with low temperature hydrogen plasma.
- deposition in discontinuous form means a succession of deposits of the same material interspersed with waiting phases in vacuum or in a controlled atmosphere, that is to say that the deposition is discontinuous over time.
- the thin layer is usually in the form of a film, and can have a thickness of between one and a few nanometers, for example between 1 nm and 10 nm. It is preferable, moreover, that the surface tension of the material situated on the surface of the support is lower than that of the material to be divided.
- the drops formed are rounded regularly, and / or distributed homogeneously. It is also preferable that these materials do not interact little or not together (few diffusion phenomena, no or few chemical reactions).
- a diffusion barrier layer may be produced beforehand, for example a TiN layer if the first material is nickel. This barrier layer will also determine the dividing properties and the stability of the divided material.
- the first material will be a catalytic metal such as nickel, iron or cobalt.
- a catalytic metal such as nickel, iron or cobalt.
- an active catalyst is obtained from 300 ° C. which can be used for growth processes.
- the step of depositing a layer of catalytic metal can be carried out in the presence of a partial pressure of oxygen, which makes it possible to better control the diameter of the grains of the catalyst.
- the invention also relates to a process for growing nanotubes or carbon nanofibers, comprising: - The production of a catalyst layer as described above, - The growth of nanotubes or nanofibers on the catalyst layer thus obtained.
- the growth of nanotubes or nanofibers can be obtained by chemical vapor deposition.
- the invention also relates to a method for producing a surface of a support with controlled roughness, comprising the production of a thin layer, for example a continuous film, of material on this support, according to one of the methods described below. -above. It also relates to a process for producing a metal / oxide mixture on the surface of a support, comprising: - the production of a thin fragmented layer of a metallic material on this support, as above, - the formation an oxide layer on the layer of material thus formed, - a polishing step.
- FIG. 1 shows a device used to carry out a method according to the invention.
- Figure 2 shows a compound according to the invention.
- FIGS. 3A and 3B represent a scanning electron microscopy (SEM) image of a 3 nm nickel film, obtained by a method according to the prior art, and by a method according to the invention.
- FIG. 4 represents nanotubes obtained by growth on a catalyst according to a process in accordance with. the invention.
- FIG. 1 illustrates a device which allows very precise control of the thickness of the layer deposited and especially the discontinuous deposition in time of this layer, moreover continuous on a surface: of a group of evaporation by electron gun having a planetary system.
- a charge 1 for example of nickel, is evaporated at room temperature through a cover 2 towards a sample holder 3 itself fixed on a planetary rotating system 5.
- a detector 4 makes it possible to control the thickness of nickel deposited on the holder -sample 3.
- the measurement, carried out using the measuring means 4 takes place over a thickness greater than the thickness deposited on the substrate 3, according to the ratio between the size of the opening 7 made in the cover 2 and the perimeter of this same cache.
- the sample holder 3 only undergoes deposition when it is in the axis of the opening 7 made in the cover, while the detector 4 undergoes a continuous deposition, during all the rotations of the planetary system.
- This device makes it possible to carry out controlled discontinuous evaporation with, for example, a deposition time of 1/10 and a deposition time of 9/10 if the size of the opening corresponds to one tenth of the perimeter of the cover.
- the structure obtained is illustrated in FIG. 2 and comprises a substrate 10, a layer, or film, 14 of deposited material, typically of thickness
- a heat treatment or a plasma treatment at hydrogen, at low temperature makes it possible to drop the deposited material, that is to say to structure the film so as to form a discontinuous set of drops of material, more or less homogeneous and / or regular in terms of their shape, size and distribution.
- this treatment can also make it possible to activate said catalyst for layer 14.
- room temperature about 20 ° C.
- 500 ° C. for example 200 ° C to 500 ° C, and preferably around 300 ° C. Examples will now be given of the production of catalysts according to the invention.
- Example 1 the material is treated by annealing.
- Layer 12 is a TiN layer 60 nm thick deposited by reactive sputtering at room temperature.
- the spray gas is a mixture of argon and nitrogen (80% / 20%).
- the Ni layer 14 is produced by electron gun at room temperature with the device described above, discontinuously. Setting drop is obtained by a standard heat treatment at 600 ° C under partial pressure of hydrogen. More generally, this heat treatment can be carried out between 500 ° C. and 600 ° C., a range conventionally used. Under these conditions, a distribution of Ni particles is obtained, the mean and standard deviation of the diameter of which are given in Table I below as a function of the thickness of Ni deposited. The results obtained on standard Ni layers (that is to say deposited continuously) are collated in Table II below.
- Table I Parameters of the particle distributions obtained according to the invention.
- FIGS. 3A and 3B each represent a SEM image of a 3 nm nickel film deposited on an identical sublayer of TiN put in drop at 600 ° C.
- FIG. 3A (x 40000) relates to the case of a standard method
- FIG. 3B (x 100000) that of a method according to the invention. Again, it appears that a gain of the order of 3 is obtained with a method according to the invention.
- Example 2 (with plasma) In this example, the material is treated with plasma.
- the deposits are the same as in Example 1 with treatment of the deposit at 300 ° C with a radio frequency plasma (RF) of hydrogen.
- the RF power is 300 W
- the treatment time 10 minutes the hydrogen pressure 150 mTorr.
- Table III illustrates the result of the treatment with a hydrogen plasma at 300 ° C. on a film deposited according to the process of the invention (that is to say discontinuously) and according to a standard process (that is to say - say continuously).
- Example 3 (partial pressure of 0 2 + plasma)
- the material is treated under partial pressure of 0 2 and with plasma.
- the TiN layer 12 is a 60 nm thick layer deposited by reactive sputtering.
- the spray gas is an argon / nitrogen mixture (80% / 20%).
- the Ni layer 14 is produced by electron gun at room temperature with the device described above. When depositing Ni, a partial oxygen pressure of 3.10 ⁇ 5 mbar is added.
- the layer is fractionated using the H 2 plasma process, as described in the previous example, at 300 ° C. Table IV collates the results relating to the size of the catalyst particles with the introduction of a partial pressure of oxygen during the deposition.
- Table IV shows the role of oxygen during the deposition of Ni.
- the diameter of the catalyst grains can be controlled by adjusting the partial pressure of oxygen, typically between 10 - ⁇ and 10 ⁇ 4 mbar.
- the catalysts produced according to the invention therefore exhibit very good thermal stability, at least up to 650 ° C. After two hours at 630 ° C., for a 3 nm layer of Ni treated with plasma, the mean distribution value increased from 18 nm to 23 nm. Nanotubes can then be grown quite satisfactorily with a CVD (chemical vapor deposition) process at 540 ° C and with C 2 H 2 as reactive gas.
- CVD chemical vapor deposition
- FIG. 4 illustrates the growth of nanotubes obtained on a catalyst according to the invention, at 540 ° C., with a CVD process at 540 ° C. (tubes of approximately 20 nm). This is a SEM image with magnification ⁇ 100,000.
- the catalyst produced according to the invention meets the following criteria: - high reactivity, at temperatures between 500 ° C and 600 ° C; - very strong division of the catalyst, the average diameter of the particles obtained can be between 10 nm and 90 nm, depending on the thickness of the catalyst; - stability under the temperature conditions used, that is to say at least up to 650 ° C; - ease of integration into the technology of a device because deposits are made at the room temperature and are therefore compatible with conventional resin "lift off” steps. We can thus easily, by these steps, locate the deposition of the catalyst.
- the invention relates more generally to a method making it possible to obtain, on one face of a support, particles of controlled density and size of a given material.
- This material can be metallic (iron, or nickel, or cobalt, or semiconductor compounds, for example silicon). It is therefore deposited discontinuously in thin film (typically a few nanometers) on the support, then drop by heat treatment or plasma treatment.
- the face of the support is chosen to interact little with the material to be divided (little diffusion, no or little chemical reaction). This is the case for nickel on TiN, but also more generally for metals on an oxide or silicon on an oxide. If necessary, a diffusion barrier can be interposed (for example in TiN, or in an oxide, etc.).
- This process can have applications other than catalysis for the growth of nanotubes.
- the particles thus distributed can be used to control the surface roughness of said support, its structuring on the scale of the size of the drops, ie approximately 20 nm. This structured surface can then be covered with an oxide (for example silica), then polished to obtain a calibrated mixture of particles, for example metallic, in an oxide (with CERMET type applications).
