Justerk Targets Semiconductor Growth Beyond Displays - thelec.net

Justerk, a South Korean precision motion control system specialist, is shifting its focus from display businesses to semiconductors and aerospace to drive future growth. In Q1 2025, semiconductor reve... Read original →

Justerk’s pivot from displays to semiconductors and aerospace reflects a strategic bet on the inflexible demand for nanometer-precision motion systems driven by HBM and advanced packaging. Its in-house direct-drive motors and thermal expansion control fill a critical gap in South Korea’s upstream equipment stack, potentially eroding Japan’s and the Netherlands’ dominance in precision stages. However, any U.S. export controls extending to advanced packaging tools would sharply raise its market entry costs in the U.S. and Japan. With rivals like ASML and IMS Nanofabrication vertically integrating motion modules, Justerk must urgently deploy IPO proceeds to certify cleanroom-compatible platforms or risk exclusion from high-end metrology supply chains. Over the next 18 months, HBM4 standardization and glass substrate packaging commercialization will create structural openings for full-stack regional players—but escalating tech decoupling may force them into difficult supply chain alignments across the U.S.-China-South Korea triangle.
