Semiconductor Manufacturing International Corp (SMIC, 中芯國際) is to build a US$2.35 billion plant with funding from the Shenzhen City Government, the first major project to emerge from China’s master plan to match the US and become more self-reliant amid a global chip shortage.
SMIC yesterday said that shortages could worsen this year and next, harming Chinese businesses if the country does not immediately increase domestic capacity.
In the joint venture with Shenzhen, the company has agreed to develop and operate a manufacturing facility that can produce chips using 28-nanometer technology, it said in a stock exchange filing.
The partners aim to attract third-party investment, begin production by next year and eventually produce 40,000 12-inch wafers per month.
“The shortage in chip manufacturing capacity is very real, and the situation could deteriorate in 2021 and 2022 if Chinese companies don’t speed up expansion,” SMIC senior vice president Zhang Xin (張昕) told the SEMICON China conference in Shanghai.
Beijing is moving swiftly to cut a dependence on the West for crucial components such as chips, an issue that became more urgent after a global shortage of semiconductors worsened during the COVID-19 pandemic.
Washington has also blacklisted major Chinese tech firms, including SMIC, cutting it off from US technology, while severely impairing its ability to procure the equipment it needs to make chips.
It remains unclear whether US President Joe Biden’s administration might allow US firms to resume selling to SMIC on a large scale, or ease up on pressuring allies in Europe and elsewhere to boycott the Chinese company.
Mergers with the government might prove essential to achieving the country’s ambitions. Chinese chipmakers aim to progress past the more mature 28-nanometer nodes — now used in industries from automaking to TVs — but need billions of dollars and years of research to produce more sophisticated semiconductors for gadgets such as smartphones.
Much of China’s hopes rest on making headway in burgeoning fields such as artificial intelligence and third-generation chips: Mainly made of materials such as silicon carbide and gallium nitride, they can operate at high frequency and in higher power and temperature environments, with broad applications in 5G, military-grade radar and electric vehicles.
SMIC’s Shenzhen project would mark one of the few plants in the country focused on larger 12-inch rather than 8-inch wafers, which save on cost because more chips can be sliced from it, but are far more difficult to fabricate.
SMIC operates fabs in four cities, including Beijing and Shanghai. It would own 55 percent of the planned factory, with a government-owned entity owning up to a 23 percent stake.
“Silicon wafer is a fundamental raw material in semiconductor manufacturing, yet it is also one of the areas in China’s semiconductor supply chain that has the lowest level of local production, especially 12-inch silicon wafers,” Li Wei (李煒), executive vice president of the National Silicon Industry Group (矽產業集團), a state-backed wafer manufacturer, told the conference on Wednesday.
WALKING AWAY: At one point the world’s No. 3 smartphone brand, LG has fallen from a position as a market leader after a series of software and hardware mishaps South Korea’s LG Electronics Inc is to wind down its loss-making mobile division after failing to find a buyer, a move that would make it the first major smartphone brand to completely withdraw from the market. Its decision to pull out will leave its 10 percent share in North America, where it is the No. 3 brand, to be gobbled up by Samsung Electronics Co and Apple Inc with its domestic rival expected to have the edge. “In the United States, LG has targeted mid-priced — if not ultra-low — models and that means Samsung, which has more mid-priced product lines than
SHORTAGE: The city government said it would install water purification machines to provide drinking water to residents and would close all public swimming pools Officials, residents and businesses in Taichung have been gearing up for water cuts that are to take effect tomorrow as Taiwan deals with a water shortage. The water supply to large parts of Taichung as well as parts of Miaoli, Changhua and Hsinchu counties is to be cut on a rotational basis for two days a week, affecting an estimated 1 million customers, the Water Resources Agency said. It is the most stringent water rationing measure introduced in central Taiwan in nearly 50 years, Taiwan Water Corp (台灣自來水) official Lin Yi-hsiung (林義雄) said. The Taichung City Government said in a statement that
SPECULATION: The integrated house and land transaction income tax has been amended as the real-estate market heats up because of high liquidity and low interest rates Lawmakers across party lines yesterday agreed to July 1 as the provisional date on which a draft amendment to the Income Tax Act (所得稅法) is to come into effect, with the aim of curbing real-estate speculation. The consensus was reached following interparty negotiations at the legislature’s Finance Committee to determine when revisions to the “integrated house and land transaction income tax” would take effect. The committee on Monday last week passed a number of revisions to the act, but failed to agree on when they would take effect. Under the proposed revisions, the tax would be set at 45 percent
TAICHUNG PLANT: An official said that generator No. 3 had been retrofitted and it generates 0.46g of particulate pollution per kilowatt-hour, down from 0.6g to 0.7g A spike in demand for electricity made it necessary to restart the third coal-fired generator at the Taichung Power Plant, Taiwan Power Co (Taipower, 台電) said yesterday as a feud with the Taichung City Government lingers. Taichung Mayor Lu Shiow-yen (盧秀燕) has sought to keep the generator from being used. In 2019, he revoked Taipower’s license to operate the generator. However, the state-run utility has taken the city government to court over the license revocation and won the case in February last year, Taipower manager Chang Ting-shu (張廷抒) said. “We would like to remind the Taichung City Government that operation of the third
