Key Insights• According to the research report, "South Korea Etching Chemicals Market Overview, 2031," published by Bonafide Research, the South Korea Etching Chemicals Market is anticipated to add to more than USD 360 Million by 2026-31.• South Korea has one of the world’s most concentrated semiconductor manufacturing ecosystems, led by Samsung Electronics and SK hynix. The country’s large scale memory, foundry and advanced logic production creates sustained demand for high purity etching chemicals used in wafer fabrication, including wet etchants and process chemicals for increasingly complex semiconductor structures.• Etching is particularly important in South Korea’s advanced memory manufacturing because DRAM and NAND production requires repeated patterning and material removal steps. The transition toward smaller process nodes, high bandwidth memory and increasingly complex 3D structures is increasing the requirement for highly selective and tightly controlled etching chemistries. • South Korea also has a strong domestic semiconductor-materials supply chain. OCI, for example, supplies semiconductor grade phosphoric acid to major Korean semiconductor manufacturers, including Samsung Electronics, SK hynix and DB HiTek. Phosphoric acid is directly used in wafer etching processes, including DRAM, NAND and foundry manufacturing.Market Overview• The rapid expansion of high-bandwidth memory is creating additional requirements for advanced wafer processing chemicals. Samsung Electronics and SK hynix are increasing semiconductor production and process capabilities to address AI-related demand, supporting consumption of specialty chemicals required for etching, cleaning, deposition and other front-end processes. • The Yongin semiconductor cluster is expected to become an important future demand center.

SK hynix plans KRW 21.6 trillion of investment by 2030 for its first Yongin fab and additional cleanrooms, with the first cleanroom opening accelerated to February 2027. The expansion will increase future requirements for semiconductor-grade etchants and other process chemicals.Policies • South Korea is supporting semiconductor technology development through government funded programs covering next generation semiconductor technologies, materials, processes and manufacturing capabilities. In 2026, the Ministry of Science and ICT allocated KRW 235.1 billion across 27 core technology projects covering semiconductors, displays and batteries. • The country is also strengthening domestic semiconductor material capabilities to reduce supply chain vulnerabilities. Local production of high purity chemicals is receiving increasing attention because semiconductor manufacturers require consistent domestic supplies of process chemicals for wafer fabrication and advanced memory production.• Chemical management is tightly controlled within major Korean semiconductor facilities. Samsung Semiconductor operates a formal chemical evaluation and tracking system covering chemical procurement, storage, use and disposal, with individual substances reviewed for environmental, health and safety risks before being approved for use. Industry Statistics • OCI is expanding its semiconductor grade phosphoric acid production capacity in Korea from 25,000 tonnes per year to 30,000 tonnes per year. The company supplies major domestic semiconductor manufacturers, and its phosphoric acid is used in wafer etching processes for DRAM, NAND flash and foundry applications. • SEMICON Korea 2026 brought together approximately 550 companies across more than 2,400 booths, covering semiconductor equipment, materials and manufacturing technologies.
