The quality of semiconductor materials directly impacts the manufacturing of semiconductor products. For instance, the performance of photoresists can directly affect the performance and integration of chips, determining the feasibility of photolithography processes. Therefore, selecting high-quality semiconductor material suppliers is crucial. Companies like JiuRi New Materials and Nanda Optoelectronics not only possess strong capabilities but also provide customers with high-quality semiconductor photoresist materials. Let’s take a look at the strengths of these companies.
JiuRi New Materials (Stock Code: 688199)
JiuRi New Materials is a photoresist supplier with a complete industry chain layout and is also the world’s largest supplier of photoinitiators. They have mastered the production process of the core raw material for photoresists—diazo naphthoquinone photosensitizers. Their affiliated company, Zhangjiajie JiuRui Bio, controls the extraction technology of key natural raw materials such as gallnut and pyrogallol, achieving self-controlled raw material supply, which significantly reduces production costs and improves efficiency for photoresists and their raw materials.
JiuRi New Materials has successfully developed over 30 photoresist formulations, with a product line covering semiconductor i-line photoresists, LED g-line/h-line photoresists, and panel photoresists, serving multiple fields including semiconductor discrete devices, integrated circuits, LEDs, and display panels. The performance indicators of their products can match those of similar imported products in the domestic market, and some models have passed downstream customer testing and achieved ton-level bulk supply, with order volumes continuously increasing.
Nanda Optoelectronics (Stock Code: 300346)
Nanda Optoelectronics primarily operates in three major areas: advanced precursor materials, electronic specialty gases, and photoresists and supporting materials. Their main semiconductor materials include ArF photoresists, electronic specialty gases, and MO sources, which are applied in the manufacturing of chips with processes of 28nm and above.
Shanghai Xinyang (Stock Code: 300236)
Shanghai Xinyang is dedicated to providing users with integrated solutions for key process materials, supporting equipment, application processes, and on-site services for integrated circuits. Their products include KrF photoresists, wafer-level packaging photoresists, electroplating solutions, and cleaning solutions, serving the manufacturing of memory and logic chips.
Rongda Photosensitive (Stock Code: 300576)
Rongda Photosensitive has long been committed to the research, production, and sales of photoresist products. Their semiconductor photoresist products mainly include G-line and I-line photoresists, with plans to enter the packaging market with their semiconductor photoresist production line by 2025.
Tongcheng New Materials (Stock Code: 603650)
Tongcheng New Materials is a platform enterprise for new materials, covering photoresists (semiconductor/display), special rubber additives, and biodegradable materials. Their subsidiary, Beijing Kehua, focuses on semiconductor photoresists. They have a high domestic market share for KrF photoresists, while ArF photoresists have passed customer validation and are in continuous mass production. EUV packaging photoresists are currently in the research and development stage.
