Dinglong Shares Invests in a Project to Produce 300 Tons of Lithography Resins per Year 2026-03-23 16:23:15 On March 20, Dinglong Shares issued a statement announcing that the \"project to produce 300 tons of KrF/ArF lithography resins per year\", which was invested in and built by its subsidiary Qianjiang New Materials, has been successfully put into operation. With the completion of this project, China’s first full-process production line for high-end wafer photoresists was established, reaching international standards and overcoming supply chain constraints. This marks a significant breakthrough for the company in the field of high-end semiconductor materials, and it also provides new impetus for the localization of semiconductor materials in China. The project put into operation by Dinglong Shares this time is the second-phase expansion. The company had previously built a 30-ton pilot production line in Phase 1 in 2022, and after its commissioning, the total annual production capacity of KrF/ArF photoresists increased to 330 tons. Compared with NanDa Optoelectronics and TongCheng New Materials, DingLong’s photoresist project boasts significant core advantages: it is the first domestic production line to cover the entire process from organic synthesis to photoresist mixing, enabling self-sufficiency in key raw materials such as core resins and special monomers, thus offering superior supply chain security and controllability ； Create highly automated flexible production lines; products cover all process stages of KrF/ArF, suitable for various applications in high-end memory and logic devices ； The production lines feature world-class intelligence and cleanliness, along with dedicated lithography machine testing laboratories and a team of high-caliber professionals across all stages of the process. This enables efficient progress from research and development to mass production, creating competitive advantages that are difficult to replicate. A variety of products are now available for stable, bulk supply. The commissioning of the project ensured full control over the entire production process, turning it into a new source of growth for the company. It strengthened the company’s presence in the field of semiconductor materials and improved the supply system in China’s semiconductor materials market. However, there is still some uncertainty regarding the future expansion of production capacity.
