[News] China Pushes Local Semiconductor Supply Chain, Taiwanese Companies Reportedly See Limited Impact

Sources have revealed that major Chinese chip manufacturers such as SMIC (Semiconductor Manufacturing International Corporation) and CXMT (ChangXin Memory Technologies) are striving to localize the supply of critical chip materials and chemicals. This move is expected to counteract U.S. export controls and could potentially exclude global suppliers from the Chinese market.

According to a report from Nikkei News, since last year, SMIC has accelerated its efforts to require customers to help monitor, verify, and adopt local suppliers. This adoption covers a range of materials used in the chip manufacturing process, including wafers, chemicals, gasses, and other essential materials. Since being added to the U.S. entity list at the end of 2020, SMIC has been continuously exploring local supply alternatives.

Reportedly, CXMT is also actively launching a similar initiative to investigate local suppliers to replace foreign sources.

These actions indicate that China’s latest localization efforts extend beyond merely increasing the use of local chip manufacturing equipment. They now encompass hundreds of chemicals, materials, and gasses, which could potentially push foreign suppliers out of the local market.

Another source cited in a report from Nikkei news mentioned that chip manufacturers are maintaining ties with global suppliers of chip chemicals to avoid sudden impacts on production quality. However, strong incentives are stimulating the development of Chinese material suppliers. For example, National Silicon Industry Group is growing into a competitor against industry leaders like Shin-Etsu Chemical, Sumco, and GlobalWafers.

Chinese chip manufacturers are also expanding their use of local sputter targets, polishing pads, slurry, and ultra-high purity chemicals and gasses. These critical chip manufacturing materials markets have traditionally been dominated by foreign suppliers such as 3M, DuPont, and Sumitomo Chemical.

Sources cited in Nikkei’s report further indicate that these actions initially apply to less advanced chip manufacturing processes, such as 55nm and 40nm, but will eventually extend to processes below 28nm.

However, as per another report from Economic Daily News, some Taiwanese companies have indicated that the impact is limited. The areas that Chinese manufacturers can capture are mostly lower-end products, while mid-to-high-end products still heavily rely on foreign suppliers for the time being.

Taiwanese companies cited by Economic Daily News point out that China has been promoting the localization of its semiconductor supply chain for many years. While policy does provide some momentum, the key issues remain quality and yield rates. Customers are said to be reluctant to frequently adopt new suppliers, making it difficult to achieve comprehensive replacement.

Industry sources cited in the same report further note that China’s localization efforts in semiconductors are primarily focused on mature processes, with more noticeable progress in the mid-to-low-end sectors. For advanced materials like photoresists and polishing slurry, products from Japan and Western countries still hold a competitive advantage in terms of yield.

Additionally, industry sources mention that China is advancing its localization efforts more rapidly in the area of small-sized silicon wafers, which are mainly used for testing rather than production. However, for 8-inch and 12-inch silicon wafers, the market is still predominantly controlled by major foreign manufacturers.
