DGIST in South Korea, together with KIST and other institutions, has developed a new near-infrared imaging sensor technology based on quantum dots and 2D semiconductors, which has now entered the mass production stage. Although the specific timing of this progress has not been explicitly disclosed, the technology’s implementation has been confirmed through official channels. Export-oriented manufacturers in security, industrial inspection, vehicle night vision, and other sectors that rely on short-wave infrared (SWIR) modules, as well as supply chain participants providing key components for them, should closely monitor the potential impact of this technology on BOM structures and procurement strategies.

Event Overview

DGIST (Daegu Gyeongbuk Institute of Science and Technology) in South Korea, together with KIST (Korea Institute of Science and Technology) and other institutions, has successfully developed a new near-infrared imaging sensor technology based on quantum dots and 2D semiconductor materials. This technology can significantly reduce the manufacturing cost of short-wave infrared sensors while delivering multiplied performance improvements. At present, the technology has already achieved mass production, and the relevant results have been publicly disclosed, but the specific start time of mass production and the scale of the first shipments have not been specified.

Which market segments will be affected

Direct trading enterprises

Infrared module exporters targeting the European and American markets (especially under OEM/ODM models) may gain access to alternative raw material solutions. The impact is mainly reflected in the following: in module BOMs that previously relied on imported high-end InGaAs sensors, some mid-to-high-resolution short-wave infrared imaging units may be replaced by new technology solutions with lower cost and comparable performance, thereby enhancing price competitiveness and delivery flexibility.

Raw material procurement enterprises

Enterprises engaged in the procurement of core materials or wafer-level components for infrared sensors will face changes in the upstream supply structure. The impact is mainly reflected in the following: demand for traditional InGaAs-based materials may undergo structural differentiation—high-end long-wave applications will remain rigid, while mid-range short-wave applications may gradually shift toward quantum dot/2D semiconductor hybrid process routes, requiring procurement technology assessments to simultaneously incorporate compatibility of new materials and production line adaptation costs.

Processing and manufacturing enterprises

Contract manufacturers undertaking infrared module mounting, packaging, calibration, and related processes will see their process adaptation capabilities affected by the physical characteristics of the new sensors. The impact is mainly reflected in the following: quantum dot-based sensors differ from traditional solutions in spectral response uniformity, thermal stability, and packaging optical matching requirements, so existing production lines may need fine-tuning of coating parameters, calibration procedures, or temperature control windows to ensure consistent yield rates.

Supply chain service enterprises

Enterprises providing cross-border logistics, customs compliance, and technical documentation localization services for infrared devices need to pay attention to changes in the classification and certification pathways of the new sensors. The impact is mainly reflected in the following: the new material system may lead to expectations of customs HS code adjustments, and the EU CE, U.S. FCC/FDA, and other frameworks may introduce additional verification requirements for EMC, radiation safety, and other tests for new photoelectric sensor modules, so service solutions need to reserve interfaces for technical compliance response.

What related enterprises or practitioners should focus on, and how they should respond at present

Pay close attention to follow-up mass production scale and the pace of opening up technology licensing

What currently deserves more attention is whether the Korean partners will open foundry manufacturing or technology licensing to third parties (including Chinese manufacturers). It is recommended that enterprises continuously track public information from the official websites of DGIST/KIST and the Ministry of Trade, Industry and Energy of South Korea, distinguish among three types of milestone signals—technology release, small-batch validation, and scaled supply—and avoid misjudging laboratory results as immediately deployable mass production resources.

Focus on evaluating the applicability of mid-range short-wave infrared module categories for the European and American markets

From an industry perspective, this technology is currently positioned more toward commercial-grade applications with mid-to-high resolution and non-extreme environments (such as -40℃~85℃). Export enterprises are advised to first sort out their own module models sold to Europe and the United States for scenarios such as security, industrial online inspection, and vehicle-mounted ADAS-assisted night vision, with unit prices in the range of 300–1500 USD, and carry out preliminary research on the feasibility of material substitution, rather than comprehensively replacing high-end scientific research or military-grade product lines.

Launch supply chain coordination contingency plans for new material introduction in advance

From the analysis, if this technology route forms a stable supply, its value to domestic infrared module manufacturers lies not only in cost reduction, but also in shortening the lead time of core components. It is recommended that procurement and R&D departments jointly formulate a “dual-source validation” plan: while maintaining existing InGaAs supplier relationships, simultaneously connect with Korean technology commercialization entities or their designated agents to complete sample receipt, driver circuit compatibility testing, and baseline reliability assessment, thereby controlling switching risks.

Differentiate between technical advantages and actual end-market certification thresholds

From observation, performance multiplication and cost reduction are laboratory indicators, while end-market access still depends on complete system-level certification results. Enterprises are advised not to directly equate improved standalone sensor parameters with higher module certification pass rates, but to simultaneously pay attention to target market requirements for RoHS and REACH compliance declarations for new photoelectric materials, as well as progress in adapting to component-level standards such as AEC-Q200 in the automotive field.

Editor’s Viewpoint / Industry Observation

At present, this is more appropriately understood as a signal of technological implementation with commercialization potential, rather than an industrial reality that has already formed a widespread substitution effect. The significance of this development lies in the fact that, for the first time in the short-wave infrared imaging field, it has validated the mass production feasibility of a heterogeneous integration route based on quantum dots/2D semiconductors, providing Chinese infrared module exporters with a second technical route option beyond traditional III-V family semiconductors. What the industry needs to continue monitoring is its yield stability in real production lines, long-term operational reliability data, and whether it will give rise to new patent barriers or adjustments to export control lists.

Conclusion

The mass production of South Korea’s new near-infrared sensor technology marks the formation of a diversified supply landscape for core components in short-wave infrared imaging. For domestic infrared module exporters, this is not an immediate cost dividend, but rather an opportunity window for restructuring supply chain resilience. At present, it is more appropriate to regard it as a technological variable that requires proactive identification, prudent validation, and phased introduction, rather than a substitute solution to be passively awaited.
