Definitions
- the invention relates to a method for the creation of nanometric structures by the self - assembly of diblock copolymers, one of whose blocks is obtained by (co) polymerization of at least one cyclic entity corresponding to formula (I) and the other block is obtained by (co) polymerization of at least one vinylaromatic monomer.
- T 0; S; C (R 7 , R 8 )
- R 1, R 2 , R 3, R 4 , R 5 , R 6 / R 7, Re are chosen from hydrogen, linear, branched, cyclic alkyl groups, with or without heteroatoms, aromatic groups with or without heteroatoms.
- the invention also relates to the use of these materials in the fields of lithography in which the block copolymer films constitute lithography masks, one or the other of the constituent domains of each block can be selectively degraded, from storage of information in which the copolymer films to blocks make it possible to locate magnetic particles in one or other of the constituent domains of each block that can be selectively degraded.
- the method also applies to the manufacture of porous membranes or catalyst supports, one or other of the constituent domains of each block can be selectively degraded to obtain a porous structure.
- the method advantageously applies to the field of nanolithography using block copolymer masks, one or the other of the constituent domains of each block can be selectively degraded in order to obtain positive or negative resins.
- the invention also relates to the block copolymer masks obtained according to the process of the invention and the positive or negative resins thus obtained, the block copolymer films containing magnetic particles in one or other of the constituent domains of the invention. each block that can be selectively degraded, the porous membranes or catalyst supports of which one or other of the constituent domains of each block are selectively degraded in order to obtain a porous structure.
- block copolymers it is possible to structure the arrangement of the constituent blocks of the copolymers, by phase segregation between the blocks thus forming nano-domains, at scales of less than 50 nm. Because of this ability to nanostructure, the use of block copolymers in the fields of electronics or optoelectronics is now well known.
- block copolymer films in particular based on polystyrene-poly (methyl methacrylate), noted hereinafter PS-b-PMMA, appear as very promising solutions because they allow you to create patterns with high resolution.
- a block of the copolymer In order to be able to use such a block copolymer film as an etching mask, a block of the copolymer must be selectively removed to create a porous film of the residual block, the patterns of which can be subsequently transferred by etching to an underlying layer.
- the PMMA block Poly (methyl methacrylate)
- PS Polystyrene
- the nano-domains must be oriented perpendicular to the surface of the underlying layer. Such structuring of the domains requires special conditions such as the preparation of the surface of the underlying layer, but also the composition of the block copolymer.
- the ratios between the blocks make it possible to control the shape of the nano-domains and the molecular mass of each block makes it possible to control the dimension of the blocks.
- Another very important factor is the phase segregation factor, still referred to as the Flory-Huggins interaction parameter and noted " ⁇ ".
- This parameter makes it possible to control the size of the nano domains. More particularly, it defines the tendency of blocks of the block copolymer to separate into nano-domains.
- the product ⁇ of the degree of polymerization, N, and the Flory-Huggins parameter ⁇ gives an indication of the compatibility of two blocks and whether they can separate. For example, a di-block copolymer of symmetrical composition separates into micro-domains if the product ⁇ is greater than 10.5. If this product ⁇ is less than 10.5, the blocks mix and the phase separation is not observed.
- US Patents 8304493 and US 8450418 describe a process for modifying block copolymers as well as modified block copolymers. These modified block copolymers have a value of the modified Flory-Huggins interaction parameter, such that the block copolymer has nano-domains of small sizes.
- the application WO 2015087003 provides improvements to the PS-b-PMMA system, however the films obtained do not allow the manufacture of masks whose respective domains constituting blocks of the block copolymers can be selectively eliminated.
- diblock copolymers one of whose blocks is derived from the polymerization of monomers comprising at least one cyclic entity corresponding to formula (I) and the other block comprising a vinylaromatic monomer, exhibit the following advantages when deposited on a surface: -A fast self-assembly kinetics (between 1 and 20 minutes) for low molecular weights leading to domain sizes well below 10 nm, and at low temperatures (between 333K and 603 K, and preferably between 373 and 603 K).
- the orientation of the domains during the self-assembly of such block copolymers does not require any preparation of the support (no neutralization layer), the orientation of the domains being governed by the thickness of the block copolymer film deposit.
- the invention relates to a nanostructured assembly process using a composition comprising a diblock copolymer, one block of which results from the polymerization of at least one monomer corresponding to the following formula (I):
- the other block comprising a vinylaromatic monomer, and comprising the following steps:
- surface is meant a surface that can be flat or non-planar.
- annealing is meant a heating step at a certain temperature allowing evaporation of the solvent when it is present, and allowing the establishment of the desired nano-structuring in a given time (self-assembly).
- Annealing also means the nano-structuring of the block copolymer film when said film is subjected to a controlled atmosphere of solvent vapor (s), these vapors giving the polymer chains sufficient mobility to organize themselves by themselves on the surface.
- Annealing also means any combination of the two methods mentioned above.
- T 0; S; C (R 7 , R 8 )
- X Si (R 1, R 2 ) in which R 1 and R 2 are linear alkyl groups, and preferably methyl groups
- Y C (R 5 , R 6) where R 5 and R 6 are hydrogen atoms
- Z C (R 3 , R 4 ) wherein R 3 and R 4 are hydrogen atoms
- T C (R 7 , R 8 ) where R 7 and R 7 are hydrogen atoms.
- the monomeric entities used in the other block of diblock copolymers used in the process of the invention comprise a vinylaromatic monomer such as styrene or substituted styrenes including alpha-methylstyrene, silylated styrenes in mass proportions. between 50 and 100% preferably between 75 and 100% and preferably between 90 and 100% within this other block.
- the monomeric entities used in the other block of the diblock copolymers used in the process of the invention consist of styrene.
- the block copolymers used in the invention are prepared by sequential anionic polymerization. Such a synthesis is well known to those skilled in the art.
- a first block is prepared according to a protocol described by Yamaoka et al., Macromolecules, 1995, 28, 7029-7031.
- the next block is constructed in the same way by sequentially adding the monomers concerned.
- One of the advantages of combining the sequence of the polymerization of the block comprising the monomer (I) with vinylaromatic monomers and more particularly styrene is the non-deactivation of a part of the block comprising the entity (I) during the synthesis of the second block on the one hand, the need not to add ethylene diphenyl to adjust the reactivities of the other species.
- the small difference in PKa of the conjugate acid of the propagating anion and the PKa of the conjugate acid of the initiating species typically less than 2 also allows the incorporation of vinylaromatic monomers and more particularly styrene. (Between 0 and 75%, and preferably between 0 and 50%) within the block comprising the entity (I), allowing a fine adjustment of the Flory Huggins parameter.
- a di-block copolymer comprising in the first block at least one monomer corresponding to formula (I) and a vinylaromatic compound, and more particularly styrene, the other block comprising a styrene compound and more particularly styrene is particularly advantageous in the context of the process of the invention and constitutes another aspect of the invention.
- the invention therefore also relates to di-block copolymers whose first block is derived from the polymerization of at least one monomer corresponding to formula (I) and a vinylaromatic compound, and more particularly styrene; the other block is derived from the polymerization of at least one vinylaromatic compound and more particularly styrene.
- the block copolymer is synthesized, it is dissolved in a suitable solvent and then deposited on a surface according to techniques known to those skilled in the art such as the so-called “spin coating” technique, “doctor blade”, “knife system” “Slot die System” but any other technique can be used such as a dry deposit, that is to say without going through a prior dissolution.
- a heat treatment or solvent vapor is carried out, a combination of the two treatments, or any other treatment known to those skilled in the art, which allows the block copolymer chains to organize themselves properly by being nanostructured, and thus to establish the film having an ordered structure.
- the films thus obtained have a thickness up to 200 nm.
- Preferred surfaces include silicon, silicon having a native or thermal oxide layer, hydrogenated or halogenated silicon, germanium, hydrogenated or halogenated germanium, platinum and platinum oxide, tungsten and oxides, gold, titanium nitrides, graphenes.
- the surface is mineral and more preferentially silicon. Even more preferably, the surface is silicon having a native or thermal oxide layer.
- the surfaces can be said to be “free” (flat or non-planar surface and homogeneous from both a topographic and chemical point of view) or to have guide structures for the "pattern" block copolymer, whether this guidance is of the chemical guidance type (called “chemistry-epitaxy guidance”) or physical / topographical guidance (called “graphoepitaxial guidance”).
- the orientation of the block copolymer is defined by the thickness of the block copolymer film deposited or induced by the use of solvent vapor annealing. It is obtained in relatively short times, between 1 and 20 minutes inclusive and preferably between 1 and 5 minutes and at temperatures between 333 and 603 K and preferably between 373K and 603 K and still more preferably between 373 and 403 K.
- Another advantage in the choice of the monomers used in the diblock copolymers used in the process of the invention is the choice of the small difference in PKa of the conjugated acid of the anion that propagates and PKa conjugated acid initiating species.
- This small difference in PKa (typically less than 2) allows the statistical sequence of the monomers and thus easily prepare a random copolymer allowing the neutralization of the surface, with the optional functionalization for the grafting of the random copolymer on the chosen surface.
- the surface may be treated with a random copolymer thus synthesized prior to deposition of the di-block copolymer, said random copolymer comprising the entity (I) and an aromatic vinyl monomer, preferably styrene.
- the process of the invention makes it possible the manufacture of positive or negative resins, which can be used in the fields of lithography, porous membranes or magnetic particle transfer media.
- the polymerization is conducted anionically in a 50/50 (vol / vol) THF / heptane mixture at -50 ° C by sequential addition of the two monomers with the secondary butyl lithium initiator (sec-BuLi).
