Semiconductor advancements: Elastic strain ‘map’ guides the fine-tuning of material properties

📅 Date:

✍️ Author: Lisa McDonald

🔖 Topics: Elastic strain engineering, Materials Science

🏭 Vertical: Semiconductor

If manufacturers are to meet the demand for semiconductors and improved computing performance, new materials and system structures must be identified and implemented. Elastic strain engineering (ESE) may help address this need. In contrast to doping, which tunes a semiconductor’s properties by adding trace amounts of other elements into the material, ESE tunes a material’s properties solely through the introduction of controlled mechanical strain. This method can be an easier way to tune the properties of wide-bandgap semiconductors, such as diamond, which are difficult to dope.

In February 2024, the researchers published their latest paper on the topic. In contrast to previous studies, which focused on answering specific open questions in the field, the new open-access paper took that knowledge and created a general “map” showing how to tune crystalline materials to produce specific thermal and electronic properties. The map, which was created using a combination of first principles calculations and machine learning, plots the stability regions of a crystal in six-dimensional strain space. Looking at the map reveals the conditions under which a material can exist in a particular phase and when it might fail or transition to another phase.

Chemicals and materials to play key role in chips as 2-nm milestone nears

🔖 Topics: Materials Science

🏭 Vertical: Semiconductor

🏢 Organizations: Entegris, Merck

James O’Neill, chief technology officer of American chip material maker Entegris, said it is no longer the chipmaking machines, but advanced materials and cleaning solutions that are taking center stage in making advanced production processes possible. “Thirty years ago, it was all about lithography [equipment] to make [transistors on chips] smaller and improve device performance,” O’Neill said. Lithography refers to the key chipmaking process in which integrated circuits are printed onto a chip. How finely a machine can print these circuits generally defines how advanced the chips are.

Kai Beckmann, CEO of Merck’s electronics business, echoed that sentiment. “We are moving from the past two decades where [chipmaking] tools are most important to advance technologies to the next decade, what our customers call the age of materials,” Beckmann said. “The tools are still important, but now materials make all the difference.”

The jump to 2-nm production for logic chips, for example, required a completely new chip architecture. In this new configuration, referred to as gate-all-around (GAA), transistors are stacked in a more complex, three-dimensional way than in earlier, planar configurations. Developing the materials for new transistor configurations like gate-all-around requires innovative materials “that will coat the top, the bottom and the sides equally,” O’Neill said, adding that the industry is engineering ways to do this “at atomic scale dimensions.”

Merck’s Beckmann gave another example of the industry’s material evolution: Copper is widely used as a conductive layer in current chipmaking processes, but to make ever smaller and more advanced chips, the industry is exploring new materials such as molybdenum.

Multiple Rounds of In Vivo Random Mutagenesis and Selection in Vibrio natriegens Result in Substantial Increases in Rare Earth Element Binding Capacity

📅 Date:

✍️ Authors: Sean Medin, Anastacia Dressel, David A. Specht

🔖 Topics: Materials Science

🏢 Organizations: Cornell University

Rare earth elements (REE) are essential ingredients to many technologies including catalysts, high-efficiency lighting, and lightweight high-strength magnets found in hard drives, wind turbines, electric vehicles, and many other applications. These magnets often utilize multiple REE such as neodymium, praseodymium, dysprosium, and terbium. The demand for these technologies is rapidly increasing, and the corresponding supply of REE needs to increase with it. Current methods of purifying REE utilize solvent extraction, which often requires high temperatures and harsh chemicals, giving these important elements a high carbon and environmental footprint.

Adsorption, or biosorption, of REE onto bacterial cell membranes offers a sustainable alternative to traditional solvent extraction methods. But in order for biosorption-based REE purification to compete economically, the capacity and specificity of biosorption sites must be enhanced. Although there have been some recent advances in characterizing the genetics of REE-biosorption, the variety and complexity of bacterial membrane surface sites make targeted genetic engineering difficult. Here, we propose using multiple rounds of in vivo random mutagenesis induced by the MP6 plasmid combined with plate-throughput REE-biosorption screening to improve a microbe’s capacity and selectivity for biosorbing REE.

🔖 Topics: Additive Manufacturing, Materials Science, Fiber Reinforced Polymers

🏢 Organizations: ETH Zurich

Advancements in additive manufacturing in composites have transformed various fields in aerospace, medical devices, tissue engineering, and electronics, enabling fine-tuning material properties by reinforcing internal particles and adjusting their type, orientation, and volume fraction. This capability opens new possibilities for tailoring materials to specific applications and optimizing the performance of 3D-printed objects. Existing reinforcement strategies are restricted to pattern types, alignment areas, and particle characteristics. Alternatively, acoustics provide versatility by controlling particles independent of their size, geometry, and charge and can create intricate pattern formations. Despite the potential of acoustics in most 3D printing, limitation arises from the scattering of the acoustic field between the polymerized hard layers and the unpolymerized resin, leading to undesirable patterning formation. However, this challenge can be addressed by adopting a novel approach that involves simultaneous reinforcement and printing the entire structure. Here, we present SonoPrint, an acoustically-assisted volumetric 3D printer that produces mechanically tunable composite geometries by patterning reinforcement microparticles within the fabricated structure. SonoPrint creates a standing wave field that produces a targeted particle motif in the photosensitive resin while simultaneously printing the object in just a few minutes. We have also demonstrated various patterning configurations such as lines, radial lines, circles, rhombuses, quadrilaterals, and hexagons using microscopic particles such as glass, metal, and polystyrene particles. Furthermore, we fabricated diverse composites using different resins, achieving 87 microns feature size. We have shown that the printed structure with patterned microparticles increased their tensile and compression strength by ∼38% and ∼75%, respectively.

Fiber reinforced polymers (FRP) provide favorable properties such as weight-specific strength and stiffness that are central for certain industries, such as aerospace or automotive manufacturing. Liquid composite molding (LCM) is a family of often employed, inexpensive, out-of-autoclave manufacturing techniques. Among them, resin transfer molding (RTM), offers a high degree of automation. Herein, textile preforms are saturated by a fluid polymer matrix in a closed mold. Both impregnation quality and level of fiber volume content are of crucial importance for the final part quality. We propose to simultaneously learn three major textile properties (fiber volume content and permeability in X and Y direction) presented as a three-dimensional map based on a sequence of camera images acquired in flow experiments and compare CNNs, ConvLSTMs, and Transformers. Moreover, we show how simulation-to-real transfer learning can improve a digital twin in FRP manufacturing, compared to simulation-only models and models based on sparse real data. The overall best metrics are: IOU 0.5031 and Accuracy 95.929 %, obtained by pretrained transformer models.

🔖 Topics: Additive Manufacturing, Materials Science

🏢 Organizations: Jabil

The slow but steady ascent of additive manufacturing (AM) into mainstream production environments is changing how products of all kinds are designed, made, and delivered. The evolution of advanced materials is further elevating the industry by empowering end-use parts and products with improved physical properties for greater utilization at lower costs as well as faster delivery and less waste.

Many, if not all, of the most popular additive materials can be enhanced through refinement of polymer formulations and compounding processes. Highly specialized skills in controlling the morphology and particle crystallization are needed, requiring chemists and scientists to create and iterate new material formulas.

In the world of AM, breakthroughs in polymer innovations are being driven by the demand for more affordable, lighter and higher-modulus composites as well as the ability to print materials that previously were too difficult to integrate into additive processes Additionally, the incorporation of value-added attributes to existing polymers is ushering in a new class of engineered materials with special functionality, such as flame-retardant or resistant attributes; reinforced materials containing glass fiber, as well as mineral fillers, carbon fiber, or nanotubes.

The inclusion of conductive attributes also is on the rise to address Electrostatic Dissipative (ESD), EMI-shielded or electrically conductive materials. The need for lubricated materials also is vital to reduce part friction and wear, along with the addition of UV-stable materials to reinforce part longevity. Many of these attributes are designed to extend the usefulness of materials for traditional manufacturing and 3D-printing applications, and vice versa.

The role of temperature on defect diffusion and nanoscale patterning in graphene

🏢 Organizations: Oak Ridge National Laboratory, Princeton University

Jesse said, “It heals locally, like the (fictitious) liquid-metal T-1000 in Terminator 2: Judgment Day.”

Graphene is of great scientific interest due to a variety of unique properties such as ballistic transport, spin selectivity, the quantum hall effect, and other quantum properties. Nanopatterning and atomic scale modifications of graphene are expected to enable further control over its intrinsic properties, providing ways to tune the electronic properties through geometric and strain effects, introduce edge states and other local or extended topological defects, and sculpt circuit paths. The focused beam of a scanning transmission electron microscope (STEM) can be used to remove atoms, enabling milling, doping, and deposition. Utilization of a STEM as an atomic scale fabrication platform is increasing; however, a detailed understanding of beam-induced processes and the subsequent cascade of aftereffects is lacking. Here, we examine the electron beam effects on atomically clean graphene at a variety of temperatures ranging from 400 to 1000 °C. We find that temperature plays a significant role in the milling rate and moderates competing processes of carbon adatom coalescence, graphene healing, and the diffusion (and recombination) of defects. The results of this work can be applied to a wider range of 2D materials and introduce better understanding of defect evolution in graphite and other bulk layered materials.

🏢 Organizations: Space Forge

Bacon and cofounder-CEO Joshua Western want to take advantage of the unique conditions in space—the very low gravity and the fact that it’s an almost perfect vacuum—to make materials that can’t be made on Earth. Some new materials have already been produced on the International Space Station. A new type of fiber-optic cable, for example, is cloudy when it’s made on Earth because of gravity and impurities in the air, but crystal clear when made in space.

In space, it’s possible to manufacture new alloys that can be used to make bigger, stronger, turbines on aircraft, so planes use less fuel. On electric planes, new materials can make the electronic connections between batteries and the propeller motor more efficient, so the planes need less cooling equipment and can carry more passengers. Space factories are also well-suited to make better batteries for electric planes or cars. Wind turbines, for example, are more efficient the larger they are, but have to be made in pieces so they can be transported to a site for installation, and then held together with bolts. By making bolts that are stronger than what can be manufactured on Earth, it’s possible to develop a larger, more efficient wind turbine that can create more energy.

🏢 Organizations: MIT

The growing popularity of 3D printing for manufacturing all sorts of items, from customized medical devices to affordable homes, has created more demand for new 3D printing materials designed for very specific uses.

A material developer selects a few ingredients, inputs details on their chemical compositions into the algorithm, and defines the mechanical properties the new material should have. Then the algorithm increases and decreases the amounts of those components (like turning knobs on an amplifier) and checks how each formula affects the material’s properties, before arriving at the ideal combination.

The researchers have created a free, open-source materials optimization platform called AutoOED that incorporates the same optimization algorithm. AutoOED is a full software package that also allows researchers to conduct their own optimization.
