Sometimes it may be necessary to prepare the surface. Among the known possibilities, there is deposited on the surface a random copolymer whose monomers may be identical in whole or in part to those used in the block copolymer composition and / or the compound to be deposited. In a pioneering article Mansky et al. (Science, vol 275 pages 1458-1460, 1997) describes this technology well, now well known to those skilled in the art.
- the surfaces may be said to be “free” (planar and homogeneous surface both from a topographic and chemical point of view) or to have structures for guiding the block copolymer "pattern", whether this guidance is chemical guidance type (called “chemistry-epitaxy guidance”) or physical / topographical guidance (called “graphoepitaxy guidance”).
- a solution of the block copolymer composition is deposited on the surface and then the solvent is evaporated 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 solution of PS-r-PMMA as described in WO2013083919 typically 2% by weight in PGMEA (propylene glycol ether-methyl acetate)
- S / MMA composition is then deposited on the clean substrate by spin coating (or any another suitable technique known to those skilled in the art to make this deposit) so as to obtain a film ⁇ 70nm thick.
- the substrate is annealed at 220 ° C for 10 minutes (or any other suitable temperature / time pair) so as to perform the covalent grafting of a monolayer of molecules on the substrate; the excess of non-grafted molecules is removed by rinsing with PGMEA.
- the PS-j-PMMA block copolymer ("BCP") or block copolymer blend solution (typically 1% by mass in PGMEA) is dispensed onto the functionalized substrate by spin coating (or another technique) in order to obtain a dry film of desired thickness.
- the film is then annealed according to the chosen technique, for example a thermal annealing at 230 ° C.
- the substrate can be immersed for a few minutes in acetic acid and then rinsed with distilled water, or the film can undergo a very mild oxygen plasma, or a combination of these two techniques, in order to to increase the contrast between the different phases of the block copolymer film in order to facilitate imaging of the nanostructures by the chosen technique (SEM, AFM ).
- the block copolymer (or mixing) solution When the block copolymer (or mixing) solution is dispensed onto the functionalized substrate, the final BCP film thickness is set at 50 nm, and the annealing for self-organization of the nanostructures is carried out at 230.degree. a variable time ranging from 5 to 20 minutes, as illustrated in FIG.
- the block copolymer mixture produced is a mixture between the reference BCPs No. 2 and No. 3, at a level of 6: 4 (60% of No. 2 mixed with 40% of No. 3). It is noted that the mixture can be made either in the solid state (for example by mixing the BCPs in powder form) or in the liquid state (for example by mixing solutions of pure BCPs of the same concentrations; concentrations of the solutions are different, mixing will be done in order to respect the fixed ratio).
- PCO "Reference # 1" serves as a reference system for the study.
- the imaging is performed on a scanning electron microscope "CD - SEM H9300" from Hitachi. Images are taken at a constant magnification of 100,000, to facilitate comparison between different systems; each image measures 1349nm * 1349nm.
- FIG. 2 the assembly obtained for different assembly times is visualized with the block-only and mixed copolymer compositions.
- Mixed copolymer compositions exhibit less defect for the same assembly times. For a given defect rate it means that the mixed copolymer compositions will assemble more quickly.
