奉贤民企打破海外垄断 超高纯金属靶材全球份额占近两成出货量占四成 在纳米级精进 为“中国芯”打通链路

Core Viewpoint - The article highlights the emergence of a Shanghai-based private company, Tongchuang Purun, which has successfully broken the overseas monopoly in the production of ultra-pure metal target materials essential for semiconductor manufacturing, capturing nearly 20% of the global market share in just two years [1][3]. Group 1: Company Overview - Tongchuang Purun was founded in 2012 by renowned electronic materials expert Yao Lijun, focusing on the research and production of ultra-pure metals such as aluminum, tantalum, copper, and manganese for chip manufacturing [3][4]. - The company has developed a modern production line capable of achieving a purity level of 6N (99.9999%), ensuring that the core technology and production processes are fully self-researched and controlled [3][4]. - As of 2023, Tongchuang Purun has become the second company globally to achieve mass production of ultra-pure manganese [4]. Group 2: Industry Context - The semiconductor industry relies heavily on ultra-pure metal materials, which are critical for the stability and performance of integrated circuits [2][3]. - Historically, the production of such high-purity materials was dominated by a few foreign companies, with domestic manufacturers facing challenges in sourcing materials and potential supply chain disruptions [2][3]. - The U.S. sanctions on China's semiconductor industry in 2019 prompted a shift towards domestic alternatives, allowing Tongchuang Purun to gain market traction with its competitive performance and cost advantages [4]. Group 3: Technological Advancements - Achieving higher purity levels in metal targets is a significant technical challenge, with each increase in purity level representing a major technological breakthrough [3][4]. - The company has invested nearly a decade in developing its products, with extensive testing and validation processes required to meet the demands of downstream manufacturers [4]. Group 4: Business Environment - The supportive business environment in the local area has played a crucial role in the company's growth, with government assistance in policy support, project expansion, and talent acquisition [5]. - Local authorities have actively engaged with the company to address challenges, ensuring that it can focus on research and development without unnecessary disruptions [5].
