Shanghai’s key chip factories look to ensure production and deliveries as city comes under phased Covid-19 lockdown
- The Pudong New Area is home to a number of factories from leading chip businesses, such as SMIC and Hua Hong
- The local government has allowed companies to operate either under a ‘closed loop’ system or allow their employees to work-from-home
Chip factories located in the semiconductor-manufacturing area of Shanghai are scrambling to ensure production and delivery after the city imposed a strict, phased lockdown from Monday to battle an outbreak of the Omicron variant of Covid-19.
Chip companies to the east and south of the Huangpu River, placed under lockdown from Monday until April 1, are facing varying degrees of disruption to their workflow and supply chains, although operations at some of the area’s largest companies remains normal, according to company statements and analysts.
The Pudong New Area is home to a number of factories from leading businesses such as Semiconductor Manufacturing International Corp (SMIC) and Hua Hong Semiconductor. Meanwhile, suburban Songjiang houses factories belonging to Taiwan Semiconductor Manufacturing Company (TSMC), the world’s largest contract chip maker.
TSMC told the Post on Monday that there was no impact on production currently, and the company was cooperating with the government. Its Songjiang factory is one of its six 8-inch wafer fabs in the world and the only one on the mainland, according to the company’s website.
SMIC, China’s largest semiconductor manufacturer, said in an online discussion with investors on Monday that the company’s production and operations remained normal with government support. The company recently revealed its plan to build a new 28-nanometre fabrication plant in the Lin-Gang Pilot Free Trade Zone, which is a part of Pudong, to address a global chip shortage.
Foundries like TSMC and SMIC may already have prepared for potential disruption to employment and inventory, before being informed by the government about lockdowns, according to Lucy Chen, vice-president at Taiwan-based Isaiah Research. “We expect the fabs may quickly raise their capacity and utility rates after the situation recovers, assuming the lockdown only lasts four days,” she said.
Wang Lifu, a Shanghai-based analyst at semiconductor consultancy ICWise, said semiconductors were one of the areas that Shanghai will look to protect. “Some engineers are expected to live and work on the factory floor for over a week,” said Wang.
