LG Chem weighs CCL expansion as AI chip demand strains supply

The AI chip boom is forcing a structural reshuffle in advanced packaging materials. LG Chem’s potential CCL capacity expansion reflects urgent demand for substrates with ultra-low dielectric loss and high thermal conductivity—critical for 2.5D/3D chip stacking. This move pressures upstream copper foil and resin suppliers to upgrade specs while pushing OSATs to qualify alternative sources faster. Amid U.S. and EU efforts to onshore semiconductor supply chains, Korean firms now face dual cost burdens from export controls and localization mandates; any geopolitical flare-up could disrupt cross-border CCL flows. Competitors like Panasonic, Taiwan, China’s ITEQ and Nan Ya Plastics will likely accelerate high-end CCL investments to capture design wins from NVIDIA and AMD. Within 18 months, CCL may become the next strategic chokepoint after photoresists and wafers, where material purity and lamination uniformity dictate AI chip yield ceilings—triggering vertical consolidation across the packaging materials stack.
