August 6, Jing Rui shares in the Panorama Network Investor Relations Interactive platform, the company's I-line photoresist has passed the core international on-line testing, high-purity hydrogen peroxide has been in the core international production line test. According to show and touch to understand, Crystal Rui shares of I-line photoresist by the subsidiary of Suzhou Rui Red Production, the Department to undertake national major science and technology projects 02 Special ' I-line photoresist product development and industrialization ', for the first time in the domestic realization I line photoresist volume production. In the Semiconductor manufacturing field, lithography and etching technology is the most important process of semiconductor chip in fine line graphics processing, which determines the minimum feature size of the chip, the 40-60% of the chip manufacturing time, and about 35% of the chip manufacturing cost. Photoresist is the key material to realize selective etching of lithography technology, accounting for about 7% of chip manufacturing cost, and is an important index to evaluate the technology level of semiconductor chip production. China's domestic photoresist products and foreign advanced products, basically behind the three, four generations or so. "National integrated circuit industry Development platform", proposed ' research and development of lithography, etching machine, ion implantation machine and other key equipment, the development of photoresist, large-inch silicon wafer and other key materials '; The state-supported High-tech Field (2015) mentions that ' high-resolution photoresist and ancillary chemicals are important components of fine chemicals and are the key development of new materials technology '; Lithography technology (including photoresist) is the focus area of China Manufacturing 2025. At present, the market of semiconductor photoresist is generally divided into sulfonated rubber photoresist, g/i line photoresist (436/365nm), Krf/arf photoresist (248/193nm). I-line photoresist is a photoresist that works at a 365nm wavelength and is mainly used in the production of 6-inch and 8-inch wafer semiconductors. Suzhou Rui Red is the earliest production of electronic photoresist chemical enterprises in China's liquid crystal display industry development process, Suzhou Rui Red for LCD photoresist made an important contribution, about 40% of the domestic market share. In the field of semiconductor photoresist in China, Suzhou Red also played an important role in the field of materials localization, and its sulfonated rubber photoresist for 4~5-inch separator accounted for about 60% of the domestic market share. I-line photoresist through the core international on-line test, for the Suzhou Red and Crystal shares, not only product upgrades, performance growth, but also represents the Chinese enterprises in the semiconductor core materials on a major breakthrough. The technical barrier of semiconductor photoresist is very high, the core technology in the global semiconductor industry involving optical resistance materials is mainly monopolized by Japanese and American companies, including Japanese JSR, TOK, Sematech, Sumitomo Chemical, USA, IBM, South Korea's chemical, etc., which add up to a market share of more than 95 %. At present, China's domestic photoresist is from low-end to high-end gradually over, China's domestic manufacturers in the semiconductor industry has mastered the G-line (436nm) and I-line (365nm) photoresist technology, is conquering KrF (248nm) and ARF (193NM) photoresist core technology. Which, in addition to the Crystal Shares department to undertake the national major science and technology projects 02 Special ' I line photoresist product development and industrialization ' project, the South Large photoelectric (sz:300346) shares of Beijing Zhongke, KrF (248nm) photoresist on a small batch in the core international through the certification, At the same time also undertook a major national science and Technology Project 02 special ' 193NM photoresist and supporting materials to start the project '; In addition, Shanghai New Yang (sz:300236) has invested in the establishment of a subsidiary to carry out 193NM (ArF) dry Faguang research and development and industrialization projects. Suzhou Rui Red is the Suzhou Electronic Materials (Group) Co., Ltd. with Japan Juon (Nipponzeon) and Japan Pill Red (Marubeni) joint venture to create a professional production of electronic chemicals company, December 20, 2011, Su Electric Company and Crystal Limited signed the transfer of equity contract, Will be held in Suzhou Red 54.56% of the equity transfer to the Crystal Limited, May 2017, the first public issue of Crystal Rui Limited IPO and IPO in the gem, the stock is referred to as ' crystal shares ', the stock code is ' 300655 '.
