Underfill materials market was valued at $540.1 million in 2025 and is projected to reach $1,076.9 million by 2035, growing at a CAGR of 7.2% from 2026 to 2035. The global underfill materials market is being shaped by the continued transition toward advanced semiconductor packaging, where materials must accommodate finer interconnects, larger dies, higher thermal loads, and increasingly complex package structures. The expansion of AI processors, high-performance computing, chiplets, 2.5D and 3D integration, and high-bandwidth memory is increasing the importance of reliable underfill solutions. Underfills provide mechanical reinforcement and help manage stresses caused by differences in thermal expansion between semiconductor dies, substrates, and interconnects. Manufacturers are therefore developing formulations with improved flow, adhesion, thermal performance, low warpage, and faster curing characteristics. Demand is also supported by automotive electronics, mobile devices, industrial electronics, and communication equipment.
Advanced Packaging Driving Material Innovation
Underfill development is increasingly linked to the requirements of advanced package architectures. Larger dies, finer pitches, greater interconnect density, and heterogeneous integration require materials that can fill narrow gaps while maintaining mechanical integrity and controlling package deformation. Suppliers are focusing on low-viscosity formulations, improved filler dispersion, higher thermal conductivity, reduced coefficient of thermal expansion, and faster curing. The development of chiplet-based architectures is particularly relevant because multiple dies and substrates increase the number of interfaces that require reliable mechanical protection. TSMC identifies underfill layers as an important buffer for managing thermal expansion mismatch in advanced CoWoS structures.
AI and HPC Increasing High-Performance Underfill Demand
AI and high-performance computing are becoming important demand drivers for advanced underfill materials because processors and memory systems are moving toward larger and more complex packages. Advanced AI packages increasingly combine logic dies, high-bandwidth memory, interposers, and chiplets, creating demanding requirements for thermal and mechanical reliability. These architectures also increase package dimensions and interconnect density, making void control, adhesion, warpage management, and stress reduction increasingly important. Packaging companies are expanding their advanced packaging capabilities specifically around AI and HPC applications, reinforcing the need for compatible material technologies. The resulting demand is encouraging suppliers to develop underfills capable of supporting high-volume manufacturing while maintaining reliability under demanding operating conditions.
Market Segmentation
Capillary Underfill Segment to Lead the Market with the Largest Share
Capillary Underfill is a leading subsegment because it remains well suited to flip-chip and other advanced semiconductor packages requiring reliable filling around dense interconnect structures. Its ability to flow into the gap beneath a die makes it useful where mechanical reinforcement and protection against thermal cycling are required. Material suppliers are improving flow characteristics so that increasingly narrow gaps can be filled with fewer voids and better process consistency. The technology also remains relevant as package designs become larger and interconnect pitches become finer. Henkel's advanced capillary underfill portfolio, for example, is designed for large-die and high-density packaging applications, while Panasonic offers capillary underfill materials for narrow-gap and narrow-pitch packages.
High-Performance Computing and Data Centers: A Key Segment in Market Growth
High-Performance Computing and Data Centers represent a rapidly expanding application area for underfill materials as AI accelerators, advanced processors, and high-bandwidth memory require increasingly sophisticated package structures. The movement toward multi-die and heterogeneous integration creates additional mechanical interfaces that require protection from thermal and physical stresses. Large package bodies and high interconnect densities also increase the importance of low warpage, strong adhesion, thermal stability, and reliable filling. TSMC states that its CoWoS technology is designed for HPC and AI products and uses underfill layers to reduce strain associated with thermal expansion mismatch.
Regional Outlook
The global underfill materials market is further divided by geography, including North America (the US and Canada), Asia-Pacific (India, China, Japan, South Korea, Australia and New Zealand, ASEAN Countries, and the Rest of Asia-Pacific), Europe (the UK, Germany, France, Italy, Spain, Russia, and the Rest of Europe), and the Rest of the World (the Middle East & Africa, and Latin America).
Asia-Pacific Region Dominates the Market with Major Share
Asia-Pacific is the dominant region in the global underfill materials market, supported by its concentration of semiconductor manufacturing, assembly, testing, and electronics production facilities. Countries such as China, Taiwan, South Korea, and Japan have established semiconductor ecosystems that generate sustained demand for advanced packaging materials. The region is also at the forefront of flip-chip, wafer-level, 2.5D, and 3D packaging development. Expansion of semiconductor fabrication and advanced packaging capacity is increasing local requirements for high-performance underfill materials. Strong consumer electronics and automotive electronics manufacturing further support demand. The presence of major material suppliers and semiconductor packaging companies strengthens the regional supply chain.
North America to Witness the Fastest Growing Region
North America is expected to be the fastest-growing region, driven primarily by expanding domestic semiconductor manufacturing and advanced packaging investments. The development of AI processors, high-performance computing systems, and data-center hardware is increasing demand for sophisticated semiconductor packaging technologies. Government support for semiconductor manufacturing is also encouraging investment across fabrication, packaging, and materials supply chains. Growing adoption of chiplets, high-bandwidth memory, and heterogeneous integration is creating additional requirements for advanced underfill solutions. The region also benefits from a strong presence of semiconductor designers, technology companies, and specialized materials suppliers. These factors are expected to support continued demand for high-reliability underfill materials.
The major companies operating in the global underfill materials market include Henkel AG & Co. KGaA, NAMICS Corporation, Shin-Etsu Chemical Co., Ltd., Resonac Holdings Corporation, and Sumitomo Bakelite Co., Ltd., among others.
