Report overview
Segments covered: substrate type, technology, package type, application, end use.
The Glass Core Substrates Market comprises glass-based packaging substrates, including through-glass via (TGV)-enabled and non-TGV glass core substrates, glass interposers, and glass-based package substrates, which serve as foundational components connecting semiconductor dies to printed circuit boards in advanced packaging architectures. Unlike conventional organic resin substrates, glass core substrates offer superior flatness and dimensional stability, lower dielectric loss, improved coefficient of thermal expansion (CTE) matching, and the potential for finer redistribution-layer patterning, making them increasingly attractive for large, high-density semiconductor packages used in AI accelerators, high-performance computing (HPC), and co-packaged optics. SEMI and Global Net Corp. identified glass core substrates as a potential USD 13 billion opportunity by 2040, highlighting their emerging role in next-generation semiconductor packaging.
The market is progressing from pilot-scale development toward initial commercial manufacturing, although large-scale adoption remains in the qualification and technology-development phase. In February 2026, SKC announced a KRW 1 trillion capital increase, with approximately KRW 590 billion allocated to its Absolics glass substrate business, underscoring the company's commitment to accelerating product development and commercialization. In May 2026, SEMI and Global Net Corp. projected that limited-volume production of glass core substrates could begin around 2028 in selected high-performance applications, with the market expected to expand at a 67.2% CAGR from 2028 to 2040 under their average scenario.
Adoption is being driven by semiconductor manufacturers and advanced-packaging ecosystem participants seeking solutions to the scaling limitations of conventional organic substrates as AI and HPC packages become larger and more complex. Intel continues to advance its glass substrate roadmap, while in July 2026 Intel announced a strategic collaboration with Lens Technology to develop glass substrate-based packaging solutions for future AI, data-center, and specialized computing workloads. At the same time, industry development is expanding across Asia, North America, and Europe, with activity spanning glass suppliers, substrate manufacturers, semiconductor companies, equipment providers, and research organizations. SEMI identifies TGV formation, metallization, build-up, dicing, cracking, and SeWaRe defects among the key technical bottlenecks that must be addressed before high-volume adoption.
Market dynamics
10 factors across 5 forcesRising Demand for AI & High-Performance Computing
The rapid expansion of AI accelerators, high-performance computing (HPC), and data-center infrastructure is emerging as a major driver of glass core substrate development, as increasingly large and complex semiconductor packages place greater demands on warpage control, dimensional stability, signal integrity, and electrical performance. According to SEMI, global semiconductor equipment billings reached a record USD 40.53 billion in Q2 2026, up 23% year over year, driven by continued investment in AI infrastructure and advanced semiconductor manufacturing capacity. SEMI also forecasts total semiconductor manufacturing equipment sales to reach USD 165.9 billion in 2026, with assembly and packaging equipment sales projected to increase 9.6% to USD 6.7 billion, reflecting growing adoption of advanced and heterogeneous packaging for AI and HBM devices.
As AI packages increase in size and integration density, conventional organic substrate materials face increasing challenges related to warpage, thermal expansion, package rigidity, and fine-line interconnect formation. Glass core substrates offer higher flatness, rigidity, dimensional stability, and improved CTE alignment with silicon, making them a potential solution for next-generation large-format packages. SEMI and Global Net Corp. estimate that the glass core substrate market could represent a USD 13 billion opportunity by 2040, with limited-volume production expected around 2028 in selected high-performance applications and a projected 67.2% CAGR from 2028 to 2040.
The continued build-out of AI computing capacity is therefore accelerating industry investment in advanced packaging technologies that can support larger dies, higher interconnect densities, HBM integration, and increasingly complex heterogeneous architectures. SEMI projects global 300mm fab equipment spending to reach approximately USD 133 billion in 2026 and USD 151 billion in 2027, with AI and HPC identified among the principal drivers of advanced logic and memory investment.
Increasing Demand for Large & High-Density Semiconductor Packages
As AI accelerator packages continue to grow in physical size to accommodate more compute and memory dies, organic substrates face mounting warpage and dimensional stability challenges that glass core substrates are specifically engineered to address. This growing package size and density is a central reason leading foundries and IDMs are accelerating glass substrate qualification programs even as the technology remains in the early stages of commercial-scale production.
