Influenced by the development history and technical constraints, the sputtering target industry started late in China and still belongs to a relatively new industry.Compared with sputtering target produced by famous international enterprises, there is still a certain gap in the research and development of sputtering target technology in China, and the market influence is relatively limited. Especially in the fields of semiconductor chip, flat panel display and solar cell, the global high-purity sputtering target market is still controlled or monopolized by sputtering target manufacturers in the United States and Japan. With the development of sputtering target in the direction of higher purity and larger size, the sputtering target manufacturer in our country can occupy a place in the global sputtering target market only if it constantly carries out R&D innovation, has strong product development capability and develops sputtering target products suitable for different application fields.

   The downstream industries such as semiconductor chips, flat panel displays and solar cells have higher requirements on product quality and stability. In order to strictly control product quality, downstream customers, especially world-renowned manufacturers, have higher barriers to supplier qualification certification and longer certification cycle when selecting suppliers. To enter the international market, China's high-purity sputtering target enterprises should first adopt the industry quality management system standards set by some international organizations and industry associations for high-purity sputtering target materials. For example, semiconductor manufacturers applied to automotive electronics generally require upstream sputtering target suppliers to pass ISO/TS16949 quality management system certification and apply to sputtering target production of electrical equipment. Businessmen need to meet the RoHS mandatory standards formulated by the European Union; secondly, well-known downstream customers such as semiconductor chips, flat panel displays, solar cells and so on have established a perfect customer certification system. 

   On the basis of high-purity sputtering target suppliers meeting the industry quality management system certification, downstream customers often qualify suppliers according to their own quality management requirements. Supplier certification. The certification process mainly includes several stages, such as technical evaluation, product quotation, sample testing, small batch trial, batch production, etc. The certification process is quite rigorous, from the development of new products to the realization of mass supply, the whole process generally takes 2-3 years. In order to reduce the cost of supplier development and maintenance and ensure the continuity of product quality, after the sputtering target supplier has passed the qualification certification of downstream customers, downstream customers will maintain a long-term stable cooperative relationship with sputtering target suppliers, will not easily replace suppliers, and incline to high-quality suppliers in terms of technical cooperation and supply share.
