Abstract

Owing to their low dielectric constant (D_k), processability, and mechanical properties, siloxane‐based polymers have attracted attention as insulating materials for next‐generation communication. However, a major challenge regarding siloxane‐containing materials is their high dielectric loss tangent (dissipation factor) (D_f). A polymer is designed and synthesized by combining polysiloxanes with phenyl side groups on the main chain and a polyimide structure (polysiloxane‐imide) to improve the D_f value. Compared with conventional dimethylsiloxane‐based polymers, the resulting polysiloxane‐imide, obtained as a bendable, self‐supporting film, exhibits a significantly reduced D_f value. The rigidity of the phenyl group‐containing polysiloxane presumably contributes to the improvement in the D_f value. Furthermore, polysiloxane‐imides exhibit excellent hydrophobicity and high heat resistance with their 5% weight loss temperature of over 400 °C. The synthesized polysiloxane‐imides with phenyl side groups, which possess various properties, including low D_k, low D_f, and excellent hydrophobicity, are expected to contribute to the future practical application of siloxane‐based insulating materials.

Abstract

High-frequency electronic applications increasingly require polymer-based insulators with low dielectric constants (D _k) and dissipation factors (D _f). Reducing molecular mobility effectively decreases the D _f of polyimides (PIs), which are widely used as interlayer dielectrics in semiconductor integrated circuits. In this study, we reduced molecular mobility by synthesizing smectic liquid crystalline polyimides (LC-PIs) via the use of diamines with phenyl benzoate structures and alkyl chains, and promoting mesogen stacking in LC structures. Self-supporting films were fabricated, and their dielectric properties were evaluated, revealing significantly lower D _f values than those of conventional PI. The functional groups responsible for increasing D _f are visualized via molecular dynamics simulations performed by applying a virtual alternating electric field to 3D models of the LC-PIs whose structure was confirmed via wide-angle X-ray diffraction. This study highlights the potential of smectic LC-PIs in the molecular design of polymeric materials with lower D _f.

Abstract

Extreme ultraviolet (EUV) lithography currently enables the creation of ultrafine patterns. However, as miniaturization progresses, stochastic defects become a significant challenge. Directed self‐assembly (DSA) of block copolymers (BCPs) has gained attention for pattern rectification to improve the quality of EUV patterns or for density multiplication to obtain sub‐10 nm features. DSA is one of the most promising miniaturization processes because it does not cause stochastic defects. However, dislocation defects are an important issue in density multiplication using strongly segregating BCP. This study demonstrates the use of DSA on 300 mm silicon wafers with higher‐Flory‐Huggins interaction parameter (χ) polystyrene‐block‐poly(methyl methacrylate) derivatives for sub‐10 nm features. These higher‐χ polymers, synthesized from polystyrene‐block‐[poly(glycidyl methacrylate)‐random‐poly(methyl methacrylate)] (PS‐b‐PGM) and 2,2,2‐trifluoroethanethiol (PS‐b‐PG_FM), show excellent reproducibility of perpendicular lamellae. Line patterns with a sub‐10 nm half‐pitch are successfully formed by DSA on 300 mm wafers. Line patterns without parallel‐oriented structures or dislocations can be achieved by optimizing the chemical guides and annealing conditions. A polymer with a higher χN value exhibits improved roughness in the resulting line patterns.

It is highly desirable to enhance the heat conduction of polymeric heat-dissipating materials for applications in power electronics, automotive components, light-emitting diodes, and telecommunication equipment. However, the thermal conductivity of polymeric materials is one to three orders of magnitude lower than that of metals and ceramics due to phonon scattering in amorphous regions. Several attempts have been made to overcome this limitation by increasing heat flow along the orientation axis of the self-assembly of liquid crystalline polymers, but the design of liquid crystalline polymers remains largely empirical. In this study, we developed a machine learning model that can predict with over 96% accuracy whether a polymer will form a liquid crystalline state based on its compositional or structural characteristics. By exploring the inverse mapping of this model, we identified a comprehensive set of chemical structures for liquid crystalline polyimides. De novo monomer synthesis and polymerization reactions of six selected polymers were performed, and all synthesized polymers were experimentally confirmed to form liquid crystalline structures with thermal conductivities ranging from 0.722 to 1.26 W m−1 K−1. These are the first liquid crystalline polymers predicted and discovered via machine learning.

Abstract

While block copolymer (BCP) lithography is theoretically capable of printing features smaller than 10 nm, developing practical BCPs for this purpose remains challenging. Herein, we report the creation of a chemically tailored, highly reliable, and practically applicable block copolymer and sub-10-nm line patterns by directed self-assembly. Polystyrene-block-[poly(glycidyl methacrylate)-random-poly(methyl methacrylate)] (PS-b-(PGMA-r-PMMA) or PS-b-PGM), which is based on PS-b-PMMA with an appropriate amount of introduced PGMA (10–33 mol%) is quantitatively post-functionalized with thiols. The use of 2,2,2-trifluoroethanethiol leads to polymers (PS-b-PG_FMs) with Flory–Huggins interaction parameters (χ) that are 3.5–4.6-times higher than that of PS-b-PMMA and well-defined higher-order structures with domain spacings of less than 20 nm. This study leads to the smallest perpendicular lamellar domain size of 12.3 nm. Furthermore, thin-film lamellar domain alignment and vertical orientation are highly reliably and reproducibly obtained by directed self-assembly to yield line patterns that correspond to a 7.6 nm half-pitch size.

Abstract

The formation of ABC triblock terpolymers through solution casting is still challenging. In this study, core–shell double gyroid network structures are fabricated via solution casting using poly(2,2,2‐trifluoroethyl methacrylate) (PTFEMA) (F)‐b‐[poly(4‐vinylpyridine) (P4VP) (P)]‐b‐[polystyrene (PS) (S)] (FPS) triblock terpolymers in N,N‐dimethylformamide (DMF). Upon heat treatment, the polymer tends to form a sphere‐in‐lamellar structure at the F/S interface. Given the solubility properties of each component in DMF, it is anticipated that the effective volume fraction of F relative to P would increase in concentrated solutions and the effective volume fraction of S would decrease. The microphase‐separated structure derived from the DMF solution consistently results in the formation of a network structure composed of a core–shell double gyroid, with F as the matrix, P as the shell, and S as the core, and their periodic lengths gradually increase to 110.8, 131.8, and 162.7 nm as increase molecular weights of PS blocks to 13.8, 20.7, and 28.8 kg mol⁻¹. Based on the solubility properties of the polymer components highlighted in this study, the solvent selection strategy is broadly applicable to ABC triblock terpolymers featuring various polymer components, offering a more efficient avenue for fabricating core–shell double gyroid structures.

Abstract

The optoelectronic properties of π‐conjugated polymers in the film state are known to be strongly affected by their structure. Inspired by this idea, the ordered‐structure‐induced electrochemical post‐functionalization (ePF) of poly(3‐(2‐ethylhexyl)thiophene) (P3EHT) films are reported. The structure of P3EHT films can be controlled by changing the solvent used to prepare them. The use of chloroform or chlorobenzene as the solvent results in amorphous P3EHT films, whereas P3EHT films with ordered structures are prepared when tetrahydrofuran is used as the solvent. The amorphous P3EHT films are not electrochemically functionalized. By contrast, ePF of the P3EHT films with an ordered structure is successful. In situ conductance measurements reveals that the successful ePF of the P3EHT films with an ordered structure originates from their greater electrochemical conductivity compared with that of amorphous P3EHT films.

Topology-transformable block copolymers based on a rotaxane structure: change in bulk properties with same composition

<title>Abstract</title>The topology of polymers affects their characteristic features, i.e., their microscopic structure and macroscopic properties. However, the topology of a polymer is usually fixed during the construction of the polymer chain and cannot be transformed after its determination during the synthesis. In this study, topology-transformable block copolymers that are connected via rotaxane linkages are introduced. We will present systems in which the topology transformation of block copolymers changes their 1) microphase-separated structures and 2) macroscopic mechanical properties. The combination of a rotaxane structure at the junction point and block copolymers that spontaneously form microphase-separated structures in the bulk provides access to systems that cannot be attained using conventional covalent bonds.

N-cyclohexylphthalimide-substituted trifluoroacetylamino (CF3CONH-) group (3TfAPI), which forms an intramolecular hydrogen bond, was synthesized, and it exhibited a bright yellow fluorescence owing to the excited-state intramolecular proton transfer (ESIPT) in the solution and crystalline states. In addition, CF3CONH-substituted phthalic anhydride (3TfAPA) was synthesized, which was attached to the termini of a blue-fluorescent semi-aromatic polyimide (PI) chain. Owing to the efficient Förster resonance energy transfer (FRET) occurring from the main chain to the termini and the suppression of deprotonation (anion formation) at the 3TfAPA moiety by H2SO4 doping, the resulting PI films display bright white fluorescence. Moreover, the enhancement of the chain rigidity by substituting the diamine moiety results in an increase in the quantum yield of white fluorescence (Φ) by a factor of 1.7, due to the suppression of local molecular motion. This material design strategy is promising for preparing thermally stable white-light fluorescent PIs applicable to solar spectral convertors, displays, and ICT devices.

Language：Japanese Publisher：The Society of Polymer Science, Japan

The development of strongly segregating block copolymers (BCPs) is essential for sub-10 nm pattern formation in next-generation semiconductor fabrication. Directed self-assembly (DSA) using BCPs addresses stochastic defects and rising costs in EUV lithography while enabling further miniaturization. This paper highlights the background and fundamentals of DSA, focusing on the design, synthesis, and phase separation control of a novel higher-χ BCP, PS-b-(PGMA_F-r-PMMA), namely PS-b-PG_FM, which exhibits χ values approximately 3.5 to 4.5 times higher than PS-b-PMMA and forms stable vertical lamellar structures with a 12.4 nm period on silicon substrates. DSA experiments on 300 mm wafers demonstrated high reliability, achieving defect-free sub-10 nm line patterns through optimized guide patterns and annealing. Additionally, new BCPs with peptide linkages at block junctions enable phase separation at lower molecular weights. Advances in higher-χ BCPs are expected to integrate DSA with existing semiconductor technologies, enabling precise, cost-effective nanoscale patterning.

We investigated the effects of nano-structure (pore size and depth) on the thermoelectric properties of porous p-Bi_<0.4>Te_3Sb_<1.6> and n-Bi_<2.0>Te_<2.7>Se_<0.3> thin films.The cross-plane thermal conductivity of the porous p-Bi_<0.4>Te_3Sb_<1.6> and n-Bi_<2.0>Te_<2.7>Se_<0.3> thin films is 0.26 and 0.22 W m^<-1> K^<-1>, respectively. The value was significantly reduced from that of standard p- and n-type flush evaporated bismuth telluride films. The figure of merit (ZT) of the porous p-Bi_<0.4>Te_3Sb_<1.6> and n-Bi_<2.0>Te_<2.7>Se_<0.3> thin films is estimated to be ZT = 1.30, 1.47, respectively. We evaluated the thermoelectric power generation of porous and flat p-Bi_<0.4>Te_3Sb_<1.6> single cell. The output power is improved 25 % by nano porous structure.

SynopsisDevelopment of a new series of self-assembling lithographic materials based on polyhedral oligomeric silsesquioxane(POSS) containing block copolymers was achieved. The POSS-containing diblock copolymer of PMMA-b-PMAPOSS was successfully synthesized via living anionic polymerization technique. Thin fi lms were prepared by spin-cast from the polymer solution on silicon wafers and subsequent solvent annealing. Dot-like nanostructures were successfully obtained in the thin fi lms. A long-range nanostructure ordering in the resulting thin fi lms was achieved by using two kinds of Directed Self-Assembly of PMMA-b-PMAPOSS.

KOBUNSHI RONBUNSHU 66 ( 8 ) 321 - 330 2009

　More details

Language：Japanese Publisher：The Society of Polymer Science, Japan

In this work, the first example of fabricating feature sizes less than 10 nm by using block copolymer lithography on an organic-inorganic hybrid block copolymer material is described. A unique class of well-defined block copolymers which contain polyhedral oligomeric silsesquioxane (POSS) was used for this achievement. Two POSS containing block copolymers (BCPs) with high a degree of polymerization of POSS and a narrow polydispersity index (PDI) were synthesized by living anionic polymerization of styrene (PS-b-PMAPOSS) or methyl methacrylate and methacrylate functionalized POSS (PMMA-b-PMAPOSS). Both BCPs indicate well-defined lamellar or cylinder microphase-separated domains. The excellent self-assembly characteristics of these BCPs in thin-films combined with the outstanding high contrast in etching resistance and etch selectivity between PS or PMMA and PMAPOSS blocks leads to well-ordered line or hexagonally packed hole structures with a hole diameter of 9 nm. A one step oxygen plasma exposure converts the soft mask into a hard mask. The synthetic flexibility and the simplicity and ease of the self-assembly and etching process make these materials very attractive for creating small feature sizes.<br>

Language：Japanese Publisher：THE JAPANESE LIQUID CRYSTAL SOCIETY

In this work, we prepared cyclic dimers C-n in which the spacers are folded between the mesogens to form an LC, and examined their characteristic LC properties. The smectic structure and the phase transition behavior are remarkably different from those in liner dimers L-n. These differences are explained as an effect of macrocyclization, which forces the spacer to fold and thereby causes the two mesogens within a molecule to face each other closely.

令和5年度の研究実施計画の大きな柱は、前年度に達成した「カーボンナノチューブ（CNT）への高分子の確実な導入とTEMによる形態観察の基礎確立」に基づいて、東工大グループで合成したカーボンナノチューブ（CNT）内部の高分子の高分解能透過電子顕微鏡観察を引き続き行った。まず、令和4年度に問題となったロータリーポンプの油による試料の汚損について、ポンプの改良を行い、その結果、汚損が生じないことを確認した。また、ハロゲンをマーカーとしたハロゲン化高分子の観察では、電子エネルギー損失分光法（EELS）による元素分析によって、ターゲットとなるハロゲン原子の存在を確認した。さらに、CNTへの導入を行うために高分子に導入しているフラーレン（C60）分子についても、内殻励起損失スペクトルの微細構造を検討し、その構造安定性について確認した。他方、CとHのみから構成される高分子については、高分子に起因するEELSスペクトルがCNTのそれと重畳し高分子からのシグナルの同定が困難となる可能性があることがわかったため、窒化ホウ素ナノチューブ（BNNT）を用いてCNTと同様の分散・高分子の内包が可能かどうか検討を行った。
また、合成面では、令和４年度に引き続き、原子移動ラジカル重合（ATRP）とクリック反応の組み合わせを用いて、片末端および両末端C60導入高分子の合成を行った。特にモノマーとして、クロロスチレンを用いた高分子に注力して検討した。また、制御型ラジカル重合（RAFT）による片末端C60高分子の合成に成功し、分子量制御について多少課題はあるもののポリスチレン（PS）やケイ素を有するPSの合成にも成功している。

With the aim of pioneering highly reliable technology for creating three-dimensional co-continuous nanostructures in polymers, we succeeded in establishing a material creation technology based on precise volume fraction control of block copolymers by the click reaction, thereby solving fundamental issues that have not yet been clarified and creating a research foundation for developing nanostructured materials that have broad potential for development. The establishment of this synthesis technology was particularly important for the development of nanostructured polymer materials. In particular, it was a significant achievement that the establishment of this technology ensured the formation of three-dimensional co-continuous structures, such as gyroid interfaces, which had been difficult to reproduce in previous research.

For developing advanced molecular placement technology and establishing a research foundation of sub-nano interface thin film materials utilizing the perpendicularly oriented interface of block copolymers, new block copolymers in which a variety of functional groups can be introduced were successfully developed.
In particular, by introducing functional groups with excellent surface segregation properties, thinning of nanodomains, perpendicular orientation control, and long-range structural ordering in thin films were established. Detailed structural analysis of the surface and cross-section of the thin films revealed the process of the perpendicular orientation of the microphase-separated nanostructures from an experimental point of view. Based on the results of these fundamental studies, a path to the establishment of elemental technologies for the development of next-generation lithography materials and sub-nano interface thin film materials were successfully achieved.

We performed molecular dynamics simulations to investigate the self-assembly mechanism of POSS-oligomer bilayer. At a first step, we selected a hybrid force field that could provide a reasonable estimate of the melting temperature (Tm) of the POSS molecules in the bulk. Note that in some previous studies, the Tm of POSS crystal was largely overestimated due to a high heating/cooling rate. Here we used the so-called interfacial method and successfully obtained the Tm much closer to the experimental value. Then, using the hybrid force field, we generated ideal POSS-oligomer bilayers that consisted of alternating POSS and oligomer layers, and characterized their thermal properties. It was found that the Tm of the POSS-oligomer bilayers monotonically decreased with the increase of the oligomer’s chain length, and that an asymmetric structure of the POSS-oligomer molecule played an important role on the thermal stability and self-assembly of the POSS-oligomer bilayers.
