Advanced Materials

Semiconductor packaging has evolved from traditional 1D PCB levels to cutting-edge 3D hybrid bonding at the wafer level, achieving interconnecting pitches as small as single micrometers and over 1000 GB/s bandwidth. Key parameters, including Power, Performance, Area, and Cost, are crucial considerations. Power efficiency is enhanced through innovative packaging techniques, while Performance benefits from shorter interconnection pitches. Area requirements vary for high-performance chips and 3D integration's smaller z-form factor.

The move towards 800V and above in electric vehicles is already well underway, spearheaded by numerous automotive OEMs such as GM, Hyundai, VW, and Lucid Motors. These platforms enhance efficiency by minimizing joule losses and allowing for the downsizing of high-voltage cabling, thus reducing weight.

Membrane materials are of fundamental importance for fuel cells, even giving their name to the specific type of fuel cell, as is the case for Proton Exchange Membrane (PEM) fuel cells. Typically, these membranes consist of ionomers containing perfluoroalkyl substances (PFAS), which in turn are subject to increasing concern and proposed regulations. In response to this, alternative materials for membranes are beginning to emerge.

IDTechEx Research announces the availability of a new report, "3D Electronics/Additive Electronics 2024-2034: Technologies, Players, and Markets". This IDTechEx report assesses the competing technologies that will enable PCBs to be replaced with integrated electronics. It covers technologies, materials, and applications of electronics added to 3D surfaces, in-mold electronics (IME), and fully printed 3D electronics.

Integrated sensors digitizing physical interactions are vital in everyday life. From personalized user experiences to warehouse inventory management, data-driven insights are driving demand for smarter sensors — and lots of them.

The chemical sector alone is responsible for 2% of global anthropogenic CO2 emissions, and the industry depends heavily on finite fossil fuel feedstocks. The new IDTechEx report, "Carbon Dioxide Utilization 2024-2044: Technologies, Market Forecasts, and Players", explores how captured CO2 could be utilized as a feedstock for hundreds of different chemicals instead.

When it comes to transport, safety is of the utmost importance, and due to the exponentially increasing demand in the electric vehicle market, the awareness of thermal runaway and potential fires from batteries is increasing simultaneously. IDTechEx's report "Fire Protection Materials for EV Batteries 2024-2034: Markets, Trends, and Forecasts" explores different battery technologies and fire-resistant materials as emerging options for dealing with the risks.

Materials informatics applies data-driven strategies to materials R&D. Long before generative AI technology reached peak hype, it had a long history of success in this field. A common approach is to use machine learning models trained on databases of material structures and properties, which then capture the underlying structure-property relationship.

Plant feedstocks are the biggest focus of companies entering the emerging alternative leather market. Companies are utilizing a very diverse selection of input feedstocks, including bamboo, grapes, apple skin, cactus, and pineapple leaves. Additionally, there are several different approaches to the incorporation of plant-based materials and the general manufacturing process.

Antenna-in-package (AiP) technology is essential for high-frequency telecommunications, as it enables the integration of antennas with RF components directly into semiconductor packages, unlike traditional discrete antennas. This advancement, tailored for mmWave applications and potentially extending into the sub-THz spectrum for 6G, promises much smaller footprints and enhanced performance.
