In the recent days, the new electronic grade sulfuric acid plant of BASF Chemical Group, located in Jiaxing, Zhejiang Province, was formally put into operation, and the ultra-pure sulfuric acid produced by it will meet the needs of domestic chip manufacturers for process upgrades in the coming years. BASF Electronic Materials Business Unit Dr. Yanning Ning, vice president of Asia Pacific, told the IT Times reporter: 'The experience of BASF's cooperation with U.S., South Korea and other chip makers will be copied to China. The ultra-high purity chemical solution can fully comply with Chinese chip manufacturers' 10nm, Demand for 7nm, or even higher chip processing. 'According to news, the above-mentioned devices have not yet been completed. BASF starts the expansion project at the same time, and the capacity will be doubled after expansion. The expansion project is expected to be put into operation by the end of this year, producing a total of 24,000 tons of high purity annually. Electronic grade sulfuric acid, can meet a considerable part of the entire Chinese chip market demand.
'In the iPhone, Huawei P20 and other star smart phones, the mobile phone chip process has reached the level of 10nm, some of the BASF customers chip manufacturers already have a 7nm and 5nm process level. To achieve such a precise chip production process, it needs trillions One-tenth grade ultrapure purity chemicals. One trillionth of a trillion is like a drop of water in the volume ratio of 20 Olympic swimming pools. ' Yaning Yan said, 'In the manufacture of less than 10 nanometers number of nodes chip In the process, hundreds of cleaning processes are required. The sulfuric acid produced by BASF's Jiaxing plant has surpassed the fastest and best-performing semiconductor standards in terms of performance, and its quality and stability are second to none in the industry.
Consulting agency SEMI data shows that in 2017, the global wafer shipment amount has reached 400 billion US dollars, and China’s capital equipment spending growth rate will be much higher than the global average. BASF expects that in 2019, Chinese mainland chip manufacturers will Realize 14nm process technology, reach 7-10nm level in 2020, fast catch up with international top craftwork level.
Dou Wei, general manager of BASF China, revealed that the Jiaxing plant will supply chip makers in Beijing, Shanghai, Nanjing, Chongqing, Chengdu, Xiamen, and other cities. At the same time, “the Yangtze River Delta is still the most demanding area for the Chinese chip industry. First, this is one of the main reasons why BASF chose Jiaxing.
According to another report, BASF is developing ultra-pure technology with one-trillionth of a higher purity. Yanning disclosed that in the labs of leading chip manufacturers collaborating with BASF, BASF has been able to provide full compliance requirements for 4nm processes. Ultrapure chemicals.
