- the invention also relates to the compositions used to improve the critical size uniformity of ordered films of block copolymers and the ordered films thus obtained which can be used in particular as masks in the field of lithography.
- Critical dimension uniformity (CDU) in an ordered film of block copolymers having a cylindrical morphology corresponds to the roll size uniformity of the rolls.
- all the cylinders must have the same diameter, because any variation of this diameter will induce variations on the performances (conductivity, characteristics of the transfer curves, evacuated thermal power, resistance, etc.) for the applications. considered. Pure BCPs organized into ordered films with as good a roll diameter regularity as possible are difficult to obtain.
- Mixtures comprising at least one BCP are a solution to this problem, and it is shown in the present invention that in the case where it is sought to obtain ordered films having a regularity of the diameter of the rolls as good as possible, the mixtures comprising at least one PCO having an order-disorder temperature (TODT), associated with at least one compound having no TODT, is a solution, when the order-disorder transition temperature (TODT) of the mixture is lower than the TODT of the BCP alone . In this case, an improvement of the CDU is observed with respect to an ordered film obtained with a single block copolymer having a TODT of equivalent period.

- the ordered film images of BCP are made on a Hitachi CD-SEM H9300.
- CD measurements are determined from SEM images with the imageJ software developed by the National Institutes of Health (http://imagej.nih.gov) following a specific treatment, although other image processing software may also be used to achieve the same result.
- the images are processed in four different steps: 1 / "thresholding" of the image to delineate the perimeter of the perpendicular cylinders (determination of the detection threshold of the different gray levels), 2 / determination of the area and diameter of the cylinders thus defined (these are assimilated to ellipsoids), 3 / distribution of the diameters of the cylinders of the image according to a Gaussian distribution, 4 / extraction of the best parameters characterizing the Gaussian curve, whose own “sigma” (the standard deviation) of this giving the value of the CDU.
- the apparent diameter of the cylinders depends closely on the threshold value of the image: when the threshold is too low, the number of cylinders detected is correct and close to its maximum value, but their diameter is underestimated hence the sigma of the Gaussian too.
- the threshold value is correct, the correct number of cylinders is detected, and their diameter is close to its maximum value, without being certain that the apparent diameter is the right one.
- the value of the threshold is too important, the apparent diameter is very close to its maximum value but by higher value (the value of the sigma is therefore possibly overestimated in this case), but a large number of cylinders is no longer detected because there is no longer any possible differentiation between the gray level of the holes and the matrix. This effect of the value is illustrated in FIG. 1 (influence of the treatment of the initial SEM image on the values of the roll diameter of the ordered BCP film, initial image: 1349xl349nm).
- the best adjustment parameters of the Gaussian curve depend on the "pitch" of it: if the pitch is too small, some frequency values will be zero even if located in the middle of the diameter range of the cylinders. On the other hand, if the step is too big, the adjustment according to a Gaussian curve no longer makes sense because all the values will take a single value. It is therefore necessary to determine the adjustment parameters of the Gaussian for different values of the pitch of the curve ( Figure 2, evolution of the characteristics (amplitude, position of the maximum, sigma value) of the Gaussian curve (solid line) adjusted on experimental values (dashed) for different step values).
- Example 1 T odt measurement by dynamic mechanical analysis. Two different molecular weight PS- ⁇ -PAM copolymers are synthesized by anionic polymerization, but commercially available products can also be used. The characterizations of these products are summarized in Table No. 1.
- the AMD makes it possible to measure the conservation modulus G 'and the loss module G' 'of the material and to determine the damping factor tanA defined as the ratio G' '/ G'.
- the measurements are made on an ARES type viscoelastic meter, on which the PLANS 25mm geometry is installed.
- the gap setting is made at the initial temperature of 100 ° C.
- the sample pellet is placed between the planes inside the oven heated to 100 ° C, a slight normal force is applied to ensure the sample-to-plane contact and thus avoid slip problems that could distort the measurement. torque and therefore modules.
- the temperature sweep is performed at the frequency of 1Hz.
- the initial strain applied to the sample is 0.1%, then it is automatically adjusted to stay above the sensor sensitivity limit of 0.2 cm. boy Wut.
- the temperature varies from 100 to 260 ° C in the bearing mode with one measurement every two degrees and a temperature equilibrium time of 30 seconds before the measurement.
- the lower molecular weight block copolymer After the rubber tray, the lower molecular weight block copolymer has a G 'lower than G''thus reflecting the destructuring of the copolymer, hence the order-disorder transition.
- the T odt is thus defined as being the first intersection between G 'and G''.
- T odt is not observed in the case of the copolymer of higher molar mass, where at any time G 'remains greater than G ". This block copolymer do not present T odt below its degradation temperature.
- Table 2 T odt of the various PS-block copolymers>
- the silicon substrates are cleaved into 2.5x2.5cm pieces, then the residual particles are removed under a stream of nitrogen.
- the substrates can be cleaned with either an oxygen plasma or a piranha solution (H 2 SO 4 / H 2 O 2 mixture in a proportion of 2: 1 by volume) for a few minutes and rinsed with distilled water.
- a solution of PS-r-PMMA as described for example in WO 2013083919 typically 2% by weight in PGMEA (propylene glycol ether-methyl acetate)
- PGMEA propylene glycol ether-methyl acetate
- 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 solution of block copolymer ("BCP") PS-j-PMMA or block copolymer mixture (typically 1% by mass in the PGMEA) is dispensed on the substrate functionalized by spin coating (or another technique ) so as 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 increase the contrast between the different phases of the block copolymer film to facilitate the imaging of nano structures by the chosen technique (SEM, AFM ).
- the block copolymer mixture produced is a mixture between the reference BCP # 2 and # 3, at 8: 2 (80% of No. 2 mixed with 20% 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. Comparisons of characteristics of realized films:
- 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.
- block copolymer mixtures according to the invention have the best results both in terms of period uniformity and critical dimension uniformity.
