Youngwoo DSP , a company specializing in optical and inspection equipment, announced that it will participate in 'SEDEX 2025 (Semiconductor Exhibition)' held at COEX in Seoul from October 22nd to 24th, unveiling a new lineup centered on semiconductor inspection equipment and formalizing its business transformation.
Through this exhibition, Youngwoo DSP showcased a number of cutting-edge semiconductor inspection and metrology solutions, including ▲2D/3D AOI (Automated Optical Inspection) wafer inspection equipment ▲CD (Critical Dimension)/Overlay measurement technology ▲Wafer edge crack inspection technology ▲DUV (Deep Ultraviolet, 129nm)-based optical design technology capable of measuring 10nm defects ▲Wafer polishing measurement technology ▲AI-based overkill filtering technology.
Among the exhibited products, the "Wafer 2D/3D AOI equipment" stands out for its world-leading WPH (Wafer Per Hour) throughput. This equipment has already been proven in the mass production lines of major domestic OSAT (semiconductor post-processing) customers.
Precision measurement technologies for next-generation microfabrication are also attracting attention. CD and overlay measurement technologies are key technologies for enhancing process precision, while optical design for measuring 10nm-level micro-defects using a DUV (129nm) laser source further enhances wafer inspection precision. Edge Crack inspection technology, which detects micro-cracks on the wafer's perimeter, was also introduced.
In addition, Youngwoo DSP also unveiled an AI-based over-filtering technology. This technology reportedly learns from minimal sample data and currently boasts an accuracy of 99.7%.
A company official stated, “Based on the optical and image processing technologies we have accumulated in the display inspection equipment field, we are actively expanding into the semiconductor inspection equipment market,” and “Through our participation in SEDEX 2025, we plan to promote the competitiveness of our semiconductor inspection and measurement technologies in the domestic and international markets, secure new customers, and diversify our business portfolio.”
