Report overview
Segments covered: substrate type, core material, application.
The growth of this market is mainly driven by surging demand for AI server and accelerator packages, the rising size and layer count of advanced packages, and growth in memory and high-bandwidth memory production. However, bottlenecks in critical materials such as T-glass cloth and build-up film, the industry's history of cyclical overbuilding, very high capital intensity, and the concentration of production in Asia restrain the growth of this market.
Furthermore, the commercialization of glass core substrates, record capacity expansion in Japan and Taiwan, and the development of second sources for critical materials are expected to offer growth opportunities for the stakeholders in this market. However, achieving yield on ever-larger, finer-line substrates remains a major challenge impacting the growth of this market. Additionally, the repurposing of existing capacity for AI, the shift toward glass and panel-level formats, and a multi-year capital expenditure cycle are prominent trends in this market.
The IC Substrates Market comprises the multilayer package substrates that connect semiconductor dies to printed circuit boards, redistributing fine-pitch chip connections to coarser board-level connections while providing power delivery, signal routing, and mechanical support. The market covers flip-chip ball grid array (FC-BGA) substrates built with Ajinomoto Build-up Film (ABF) for CPUs, GPUs, AI accelerators, and networking chips; flip-chip chip scale package (FC-CSP) and wire-bond substrates built on bismaleimide triazine (BT) resin for mobile processors, memory, and RF devices; system-in-package and module substrates; emerging glass core substrates; and ceramic substrates. Silicon interposers and standard printed circuit boards are excluded. The market ecosystem extends from suppliers of build-up films, glass cloth, copper foil, and laminates to substrate manufacturers, outsourced assembly and test providers, chipmakers, and system builders.
AI is driving a new upcycle. Ibiden, a leading supplier of substrates for server processors and AI accelerators, reported fiscal 2025 (April 2025 to March 2026) revenue of JPY 416.2 billion, up 12.7%, with its Electronics business, centered on IC substrates, growing 23.4% to JPY 243.3 billion and operating profit rising 68.5% to JPY 45.2 billion, as strong AI server orders and a moderate recovery in general-purpose servers offset weaker-than-expected PC demand. Ibiden forecasts fiscal 2026 revenue of JPY 500 billion, up 20.1%, and operating profit up 45.1%. Its president stated that demand for AI server substrates continued to exceed capacity, and the company plans to increase substrate output, measured by package area, by 150% by fiscal 2027 compared with fiscal 2024.
Suppliers are investing at record levels. Ibiden opened its Ono Plant in Gifu Prefecture on 10 October 2025, beginning sequential mass production primarily for AI server products, and in February 2026 announced a JPY 500 billion investment over fiscal 2026 to 2028, including about JPY 220 billion at its Gama Plant and about JPY 280 billion at its Ono Plant and other sites, with new capacity starting from fiscal 2027. In Taiwan, the three largest PCB makers have budgeted record 2026 capital spending of more than NT$160 billion, with Zhen Ding Technology alone budgeting more than NT$50 billion, up 60%. Unimicron's chairman has forecast that AI-application PCBs will surpass smartphone PCBs in global market value by 2029.
Materials and geography are the key constraints. T-glass fiberglass cloth, essential for both ABF and BT substrates, is in acute shortage; Japan's Nittobo, which dominates supply for ABF applications, is investing JPY 150 billion to triple capacity, but meaningful relief is not expected before mid-to-late 2026, with full impact likely in 2027, while Taiwanese producers including Nan Ya, Taiwan Glass Industry, and Fulltech Fiber Glass are expanding into T-glass. At the same time, the U.S. Department of Commerce has noted that the advanced packaging substrates market is concentrated in Asia; in December 2024 it finalized up to USD 75 million in CHIPS Act funding for Absolics, a subsidiary of Korea's SKC, to build a 120,000-square-foot glass substrate facility in Covington, Georgia, the first CHIPS investment in a commercial facility manufacturing a new advanced material.
Market dynamics
16 factors across 5 forcesSurging Demand for AI Server and Accelerator Packages
Surging demand for AI server and accelerator packages is a major factor driving the IC Substrates Market. Ibiden reported that its IC substrate-based Electronics business grew 23.4% to JPY 243.3 billion in fiscal 2025, with operating profit up 68.5% to JPY 45.2 billion, driven by strong AI server orders, and forecasts group revenue growth of 20.1% to JPY 500 billion in fiscal 2026 as demand for high-performance substrates increases further. Its president stated that demand for AI server substrates continued to exceed capacity. AI accelerators and server processors use large, high-layer-count ABF substrates with high value per unit, making AI the most significant source of value growth in the market.
Rising Size and Layer Count of Advanced Packages
The rising size and layer count of advanced packages are significantly increasing substrate area and value per chip. Ibiden plans to increase its IC substrate output, measured by package area, by 150% by fiscal 2027 compared with fiscal 2024, and expects its capacity for AI substrates to reach around 2.5 times current levels by fiscal 2028, according to reports. Multi-chip AI packages combining GPUs and HBM stacks require larger substrates with more build-up layers and finer lines, and Unimicron's chairman has forecast that AI-application PCBs will surpass smartphone PCBs in global market value by 2029.
Growth in Memory and High-Bandwidth Memory Production
Growth in memory and high-bandwidth memory production is increasing demand for BT and memory substrates. SK hynix reported third-quarter 2025 revenue of KRW 24.449 trillion, up 39% year on year, and planned to begin HBM4 shipments in the fourth quarter of 2025. A strong memory cycle has tightened supply of BT substrates for memory chips, which, like ABF substrates, depend on scarce T-glass cloth. Growing memory content in AI servers, PCs, and smartphones is expected to sustain demand for FC-CSP and wire-bond substrates.

Expert perspectives
The IC Substrates Market has moved from glut to shortage in less than three years. Ibiden's idle Gama Plant, built for a customer whose demand fell away, is now being brought into production because AI server demand exceeds capacity, and the company has committed JPY 500 billion to expansion. The binding constraint has shifted upstream to materials such as T-glass cloth, where a single dominant supplier sets the pace for the entire chain.
Three structural changes are expected to shape the market through 2036. First, AI packages will drive substrate area and value, with output measured by package area rising far faster than unit volumes. Second, glass core substrates will move from pilot to production, beginning with Absolics' Georgia plant, and gradually take share in the largest AI packages. Third, supply chains will diversify, with second sources for critical materials and new substrate capacity in North America, Southeast Asia, and Europe.
For companies planning entry or expansion, the most attractive positions over the forecast period are likely to be found in high-layer-count ABF substrates for AI, glass core substrates, critical materials such as T-glass and build-up films, and substrate capacity in North America and Southeast Asia. The principal risks are materials bottlenecks, the industry's history of cyclical overbuilding, and technology transition risk.
