China polishing material industry market development status in 2019
According to buck information released by the China CMP polishing materials market research and investment strategy report (2019 edition) ", according to CMP (chemical mechanical polishing (ChemicalMechanicalPolishing) technology is one of the key process in semiconductor manufacturing process, using the "soft grinding hard" principle of wear, and play with a softer material for polishing to achieve the high quality of surface polishing. Through the comprehensive action of chemical and mechanical, the surface damage caused by mechanical polishing and the slow polishing speed, poor surface flatness and polishing consistency easily caused by chemical polishing are avoided.
With the continuous progress of IC chip process technology, the integration level of chips has been continuously improved, which makes the wafer manufacturing requirements on the surface flatness of silicon wafers continue to improve, so the demand for CMP process continues to increase. For example, silicon wafers needed for deep submicron DRAM require 3-6 CMP cycles, and deep submicron MPU require 9-13 CMP cycles. According to data, the global market size of CMP polishing materials reached us $1.59 billion in 2015 and us $1.72 billion in 2017.
At present, the polishing pad is mainly monopolized by dow chemical company, with a market share of about 90%. Other suppliers include toray of Japan, 3M, tri-party chemical of Taiwan, Cabot and other companies, with a total share of about 10%. Polishing fluid, the main suppliers include Japan Fujimi, HinomotoKenmazai, the United States Cabot, dupont, Rodel, Eka, South Korea ACE and other companies, occupying more than 90% of the global market share, the domestic market mainly rely on imports.
We need to take good steps, walk steadily, constantly improve and promote the development of the market.
In modern times, the production process of rare earth polishing powder has been basically finalized, and has been widely used in all walks of life.
At present, the polishing pad is mainly monopolized by dow chemical company, with a market share of about 90%.
According to wang zhimin's calculation, there are about 850,000 m3 catalysts in operation in China during the 13th five-year plan period, and it is expected that the waste vanadium and titanium denitrification catalyst will be replaced annually from 2018 up to 300,000 m3.
On the other hand, the chapter should build up development consensus, strengthen exchanges and cooperation, lead enterprises to go abroad, create a broader international stage, and improve the international discourse and influence of China's rare earth industry.
Grinding powder particles have certain crystal shape, forming sharp edges and corners when broken, so as to improve polishing efficiency;
