The Glass Substrate Market is transitioning from advanced research to structured commercial execution. A February 3, 2026 report published by TrendForce states that Samsung Electro-Mechanics has shifted its glass substrate initiative from an advanced research and development unit to a business-focused execution team. This internal restructuring signals a clear move from development to market deployment. According to the same report, Samsung expects the glass substrate era to enter full swing from 2027 onward. The company is currently developing glass substrate samples with customers, including global semiconductor firms, indicating early commercial engagement.
Glass Substrate Market and AI Chip Demand
Glass substrates replace conventional plastic materials in semiconductor packaging. As cited by TrendForce referencing ETNews, glass offers reduced warpage and enhanced support for ultra-fine circuit patterning. These characteristics are particularly relevant for artificial intelligence chips that require structural stability and precision interconnections. The report notes that companies including Samsung Electronics, Intel, Broadcom, AMD, and Amazon Web Services are actively moving to adopt the technology. This indicates that adoption interest spans integrated device manufacturers, chip designers, and cloud infrastructure providers.
Glass Substrate Commercialization Roadmap
| Company | Strategic Actions (2025–2026) | Commercial Objective |
| Samsung Electro-Mechanics | Shifted project from R&D to business unit; established pilot line in Sejong; formed JV for glass cores; invested in advanced LMCE processing technology | Full-scale ramp-up from 2027 |
| SKC (Absolix) | Preparing for mass production; diversifying photoresist supply; expanding partnerships for glass through-via and plating processes | Mass production targeted for 2026 |
| LG Innotek | Invested in precision glass specialist UTI; co-developing strengthening technologies; setting up pilot production line | Testing feasibility for mass production |
From Pilot Line to Supply Chain Integration
The commercialization roadmap includes tangible operational steps. TrendForce reports that Samsung Electro-Mechanics established a pilot line for glass substrate prototypes at its Sejong facility in 2025. This facility supports sample development and early-stage validation with customers. In November 2025, the company agreed to form a joint venture with Sumitomo Chemical Group to accelerate the production and supply of glass cores, a critical component of semiconductor glass substrates. Securing glass core supply strengthens vertical integration and reduces material dependency risks. Additionally, AlphaBiz, as cited in the TrendForce report, states that Samsung Venture Investment Corporation acquired a stake in JWMT in late 2025. JWMT developed proprietary LMCE technology that uses lasers to modify the physical properties of glass and selectively dissolve targeted areas with chemicals, avoiding direct drilling. The company also offers plating processes and full-scale solutions.
Competitive Developments in the Glass Substrate Market
Competitive activity is accelerating alongside Samsung’s efforts. According to Chosun Biz, as cited by TrendForce, SK Group’s subsidiary SKC plans to begin mass production of glass substrates in 2026. Ensuring stable supply while refining the technology remains a priority. SKC’s Absolix unit is diversifying its photoresist supply, previously dependent on Japan’s TOK, and is exploring additional partners for glass through-via and plating processes. This dual-sourcing strategy aims to strengthen supply stability and reduce concentration risk. The same report indicates that LG Innotek is expanding into glass substrates by investing in UTI, a precision glass processing specialist. LG Innotek is co-developing strengthening technologies and establishing a pilot production line to test mass production feasibility.
Next Steps
- Closely monitor SKC’s planned 2026 mass production to evaluate early commercialization performance and supply stability.
- Track Samsung Electro-Mechanics’ customer sampling progress ahead of its expected 2027 ramp-up to assess adoption momentum.
- Assess developments in the Samsung–Sumitomo Chemical joint venture to determine scalability of glass core supply.
- Evaluate advancements in laser-based LMCE processing technology to understand manufacturing efficiency and precision improvements.
- Analyze competitive pilot line expansions from LG Innotek and other entrants to gauge shifts in market positioning between 2026 and 2027.
Conclusion
The Glass Substrate Market is no longer confined to research laboratories. Samsung’s internal restructuring, pilot line deployment, and supply chain partnerships indicate measurable commercialization intent. SKC’s 2026 mass production plan and LG Innotek’s pilot expansion further demonstrate that competitive positioning is unfolding in real time. Based strictly on the February 3, 2026 TrendForce report, the period between 2026 and 2027 is expected to define operational maturity, supply stability, and large-scale adoption in next-generation semiconductor packaging.
