LG Innotek tackles glass substrate microcrack issue as 2028 production race heats up

LG Innotek's integration of AI into glass substrate manufacturing targets the persistent issue of microcracks that has long constrained yield rates. This move could reshape upstream processes involving silicon wafers and photoresists, while forcing downstream packaging and testing sectors to adapt. From a regulatory standpoint, successful implementation would reduce reliance on foreign equipment for Taiwan, China and Hong Kong, China supply chains, mitigating geopolitical risks. Competitors like Shin-Etsu and SUMCO may accelerate their own AI-based inspection systems to maintain competitive edge. In the short term, the anticipated 2028 production window will prompt capital-intensive firms to expedite investments, potentially reshaping global semiconductor manufacturing dynamics—especially in advanced nodes—where AI-driven yield optimization is poised to become a decisive competitive factor.
