Photoresists(SK materials performance)

Photoresists are photosensitive materials indispensable for photolithography, the core process that defines ultra-fine circuit patterns on semiconductor wafers. The quality and consistency of photoresists directly impact device yield and process reliability, making stable supply and continuous innovation essential. SK materials performance leads the industry by supplying advanced EUV photoresists that enable device scaling and high integration, as well as complementary materials such as bottom anti-reflective coatings(BARC) and spin-on hardmasks(SOC). Leveraging our expertise in high-performance polymer chemistry, we support the realization of high-speed, low-power AI semiconductors, contributing to the expansion and competitiveness of SK ecoplant’s AI semiconductor manufacturing ecosystem.

Etching Gases(SK rezonac)

Etching gases are critical process materials used to selectively remove specific layers during semiconductor device fabrication, enabling the precise pattern transfer essential for advanced circuit integration. SK Rezonac is the first in Korea to establish a dedicated production line for high-purity monofluoromethane(CH₃F), renowned for its superior selectivity and process control in etching applications. In addition, we have built state-of-the-art facilities for hydrogen bromide(HBr), a next-generation etching gas, ensuring a stable and diversified supply portfolio of high-purity etching gases. As the demand for high-performance, high-density semiconductors accelerates with the growth of AI workloads, SK Rezonac’s robust supply capabilities and advanced material technologies reinforce the technological foundation of SK ecoplant’s AI semiconductor infrastructure strategy.

Precursors(SK trichem)

Precursors are highly specialized chemical materials used in atomic layer deposition(ALD) and chemical vapor deposition(CVD) processes to form ultra-thin, uniform films on semiconductor substrates. As device geometries shrink and 3D architectures become mainstream, the demand for advanced precursor solutions continues to rise. SK trichem develops and supplies a broad portfolio of metal-organic and inorganic precursors, including zirconium, tantalum, and titanium compounds, tailored for next-generation device fabrication. Through close collaboration with customers and research institutions, we continuously enhance our R&D capabilities to deliver innovative material solutions.By ensuring reliable supply and process-optimized materials, SK trichem strengthens the technological completeness and supply chain resilience of SK ecoplant’s AI semiconductor infrastructure.

Blue Dopants(SK materials JCN)

Blue dopants are essential emissive materials for the blue sub-pixel in OLED displays, a key determinant of display resolution and color purity. Due to their short wavelength and limited operational lifetime, blue dopants represent one of the most challenging areas in OLED material science. SK materials JNC develops and supplies high-efficiency blue dopants and other core OLED materials, supporting the realization of high-resolution, energy-efficient displays. Our accumulated expertise in organic material synthesis and stringent quality control contribute to enhanced performance and durability across a wide range of display applications. As the adoption of AI-enabled devices drives demand for advanced display technologies, SK materials JNC plays a pivotal role in SK ecoplant’s AI infrastructure ecosystem by delivering innovative materials that enable next-generation user experiences.
