Intel's No SeWaRe Glass Substrates: TGV Challenges and Advanced Packaging Supply Chain Role
With Google, Meta, and MediaTek all considering adopting Intel’s EMIB packaging technology, Intel’s technological progress in advanced packaging and glass substrates has once again attracted significant attention in the industry. In particular, Intel showcased the first sample at NEPCON Japan on January 22nd 2026 that combines Intel’s EMIB packaging with a glass substrate, capable of supporting a chip twice the reticle size, with bump pitch shrunk to 45µm, and claimed to have achieved No SeWaRe (no micro‑cracks) during testing, implying that glass substrates are one step closer to mass production. On the other hand, besides Intel, TSMC, Samsung (SEMCO), Rapidus, and SK Absolics are also expected to achieve mass production of glass substrates successively between 2027 and 2028.
This report mainly provides in‑depth analysis of: (1) trends in large‑size chip packaging; (2) the advantages of glass substrates; (3) the glass substrate technology roadmaps of major foundries/OSATs; (4) challenges in mass production of glass substrates; (5) glass substrate solutions and corresponding suppliers; and (6) an overview of the glass substrate supply chain and opportunities for Taiwanese manufacturers. This report analyzes current demand drivers for glass substrates, technological bottlenecks, supplier performance, and potential supply‑chain opportunities for Taiwanese companies.
