Definitions
- the present invention relates to a process for producing organized 3D nanostructures, in particular in semiconductor material.
- the nanostructures are in the form of a network. They are produced on a substrate which may be a dielectric layer, for example made of Si0 2 , or Al 2 C> 3, or Si 3 N 4 , or Hf0 2 or another metallic oxide.
- These nanostructures are intended for the production of optical or opto-electronic electronic devices (memories, tansistors with 1 electron). These are in particular coulomb blocking devices using quantum dots.
- These nanostructures are also intended for the production of probes for biochips, a piece of DNA that can be attached to a nanostructure.
- Chemical vapor deposition allows nanostructures to be deposited industrially on a dielectric. These nanostructures have already been able to be integrated into devices such as memories or transistors.
- the deposition of silicon nanostructures (ns-Si) on dielectric by CVD involves the formation of a new layer of silicon, by CVD, from precursors such as silane or disilane, is of the ' Volmer-ebber type : are first formed three-dimensional islands which grow until coalescing before forming a continuous layer. It is thus possible, by stopping the growth during the first stages of the deposition, to obtain islets of nanometric dimensions.
- the main limitation of this technique is that the nanostructures are arranged randomly on the substrate, as indicated in the reference [1] cited at the end of this description. This is due to the spontaneous nature of the nucleation process of silicon on dielectric. These nanostructures actually form preferentially on sites or faults which it is not currently possible to. check the arrangement on the surface of the substrate. This severely limits the quality and performance of devices based on such structures. To manage to organize the distribution of these nanostructures, it is therefore necessary to create preferential nucleation sites regularly distributed on the surface of the substrate. For this, it has been proposed to deposit the nanostructures on a Si0 2 substrate having a regular deformation field on its surface.
- the nanostructures deposited on this kind of substrate are organized along lines, as described in reference [2] cited at the end of this description.
- the resulting organization is not satisfactory and the spacing between the nanostructures is very difficult to control.
- this method requires the use of very fine dielectrics which do not guarantee electrical insulation between the nanostructures and the substrate. The problem therefore arises of finding a method for controlling the. localization and growth of nanostructures.
- the present invention creates a regular network of nucleation sites to control the location and growth of nanostructures. These are for example deposited by chemical vapor deposition (CVD) on a substrate, which may advantageously be made of a dielectric material. In other words, the present invention makes it possible to organize the nanostructures on a surface. First, the surface of the substrate is locally functionalized by depositing a nucleation site using a focused ion beam.
- CVD chemical vapor deposition
- FIB for example a beam of silicon ions or germanium ions.
- the nanostructures grow, for example by chemical vapor deposition (CVD), selectively on the nucleation sites previously formed by the FIB.
- CVD chemical vapor deposition
- nucleation centers are therefore regularly deposited by means of a beam of focused ions FIB (Focused Ion Beam).
- FIB focused ions
- Three-dimensional nanostructures then grow selectively on the nucleation centers thus formed.
- the invention makes it possible in particular to produce, on insulator, an organized deposition of semiconductor nano-structures, for example of silicon or Germanium or in semiconductor material of column IV or of type III - V. It is also possible to prepare metallic nanostructures.
- the localization of these nanostructures is controlled since the FIB allows a very local irradiation, therefore the formation of very localized growth sites, and allows a control of the spacing between nanostructures. Finally, the density of these nanostructures is also controlled, since it is equal to the density of sites created by FIB.
- the size of the nanostructures is therefore properly controlled, and the size dispersion is reduced compared to a random deposition of nanostructures.
- the element used to irradiate may be the same as, or may have properties close to, the constituent element of nanostructures. The electrical or optical properties of the nanostructures are therefore not degraded by the presence of impurities.
- Figures 1 and 2 represent steps of a method according to the invention.
- a method according to the invention will be described in connection with FIGS. 1 and 2.
- a surface 2 is exposed to an ion beam in order to locally deposit therein a material which will serve as preferential nucleation sites 4, where the nanostructures can then grow.
- an ion beam focused in FIB Fluorine Beam
- FIB workstation used for this purpose, enables the ion beam to be focused very precisely on the surface of substrate 2 with a very high current density. Such a workstation is for example described in the document 4 cited at the end of this description.
- the exposure of predetermined areas of the surface to the focused ion beam (FIB) generates a local modification of the properties of the substrate 2.
- a reactive site 4 created by irradiation with the ion beam can be, for example, a cluster (a few atoms) of the element used to irradiate the surface, or an introduction of this element into the substrate, or alternatively defects created by ion bombardment (or implantation). Nucleation sites 4 are therefore first created at the chosen positions, by irradiation of the surface with a localized ion beam (FIB).
- the element used to irradiate the surface preferably has properties close to the constituent element of the nanostructures which it is desired to produce. To make nanostructures of silicon or germanium, it is possible to irradiate with, for example, silicon. We can also use a germanium beam.
- a precursor is preferably used which generates a selective deposit on the site relative to the substrate.
- the dielectric is Si0 2 and if the prior irradiation is done with silicon, it will be possible to deposit nanostructures of silicon or germanium using respectively Dichlorosilane or Germane, which are precursors making it possible to generate a deposit on a site of selective silicon with respect to an Si0 2 substrate. This is particularly the case if the irradiation is such that aggregates of silicon or zones rich in silicon are formed on the surface of the substrate. The nanostructures therefore grow selectively over the irradiated zones 4.
- the desired material is, for example, selectively deposited on the nucleation sites 4 by chemical vapor deposition (CVD).
- CVD chemical vapor deposition
- a deposit of the nucleation site (a few atoms of a chosen material) is therefore first obtained by FIB, while the FIB technique is known to be in principle ineffective for obtaining a 3D nanostructure, or in volume. Then comes the selective growth of nanostructures 8 on the growth germs deposited by FIB.
- each nanostructure is thus well localized and its size controlled (maximum diameter D, measured in a plane parallel to plane 2, of the order of a few nanometers, for example between lnm and 10 nm or 15 nm or 20 nm, the height is for example around 100 nm, and the approximate shape of these structures is between a hemisphere and a sphere In microelectronic applications the height will be less than 20 nm and advantageously of the order of 10 nm.
- the nanostructures thus regularly arranged are formed at a density which may be between 10 8 / cm 2 and 10 13 / cm 2 .
- the size dispersion obtained is less than 20%: when we average all the sizes, we obtain a difference between crystals of less than 20%.
- the intervention of an electrochemical process is not essential for obtaining such selective growth as in certain known processes.
- various heat treatments can be carried out to improve their electrical or optical properties, in particular to cure the defects caused by irradiation in the substrate 2.
- the invention relates to all materials which have a selectivity of deposition with respect to substrate 2. The irradiation with FIB then brings the nucleation site to the deposited material.
- a substrate which may be of an insulating nature (for example Si0 2 , A1 2 0 3 , SiN x , ...), materials from column IV (for example silicon carbide Sic, Diamant C.), or III-V materials (gallium arsenide, gallium nitride, GaP ....), or metals ...
