Almost two-thirds of SMIC's Shanghai employees are living at work

Closed-loop factories are all the rage as COVID rages on, despite China’s insistence that the virus stop


Over 60 percent of Semiconductor Manufacturing International Corporation's (SMIC) Shanghai staff are living around the factory campus, in accordance with the ongoing city-wide COVID lockdown, the Chinese semiconductor foundry confirmed this week.

The workers in the eastern Pudong district's Zhangjiang complex, an area known as the epicenter of Shanghai's chip industry, are operating in a "closed loop" system, meaning they have no contact with the outside world as they live and eat at (or at least very near) their place of employment.

The company said it had resumed full production after a brief period of being partially affected by lockdowns in mid-April.

According to reports decribing the "closed-loop management of the Zhangjiang plant and two living parks", the chipmaker implemented the system on March 18, and more workers re-entered the closed loop after being given the green light from the government.

The Shanghai administration issued a list of 666 enterprises to resume production if they managed COVID prevention strategies correctly. As of last week, 70 percent of those on the "white list" had resumed some operations, including Science Applications International Corporation (SAIC) and Tesla. A third of the companies on the list were auto manufacturers and suppliers.

The 25-million-plus residents of Shanghai have been under strict lockdown since the week of March 28th.

Residents, including those who work in logistics and manufacturing such as delivery drivers and factory workers, are confined to their homes, with many reporting difficulty getting food, medicine, and other essentials. The government has delivered vegetable boxes to registered residents, though many have said the supplies are not enough and they are still hungry.

The tech-savvy among the populace have turned to e-commerce to secure supplies and negotiate contactless trades among neighbours.

Presumably, those working in SMIC's closed-loop system are not expected to source their own food, although details over SMIC's dining arrangements were not released and SMIC had not responded to requests for comment by the time of publication.

But the closed-loop system is not a new concept. Factories in Vietnam had on-site arrangements last year as vaccine rates hovered around four percent and outbreaks of COVID's Delta strain hit the SouthEast Asian country.

The closed-loop factory systems in Vietnam lasted around a month.

Meanwhile, Shanghai's lockdown and subsequent closed-loop factories have no predicted end in sight.

Beyond bulk neighborhood buys and closed-loop factories, trucks have had difficulty getting in and out of Shanghai, thereby complicating all logistics and greatly exacerbating an already choked supply chain. Factories are hindered from making components or systems, as well as receiving and delivering parts to business partners which thereby complicates shipping finished products.

According to market intelligence firm TrendForce, electronics makers are predicted to have difficulty securing processors, battery modules, panel materials and certain multi-layer ceramic capacitors (MLCCs) going into things like servers and vehicles.

Meanwhile, the clock is ticking on China's US sanction-inspired 2035 self-sufficiency goals. It was already doubtful that the Middle Kingdom would meet its goal of making 70 percent of its own semiconductors domestically by 2025.

SMIC is an important part of achieving those chip goals as it was the fastest growing wafer foundry last year. The semiconductor manufacturer made $5.4 billion in revenue in 2021, an increase of 39 percent year-on-year. ®

    Imagine a future where racks of computer servers hum quietly in darkness below the surface of the Moon.

    Here is where some of the most important data is stored, to be left untouched for as long as can be. The idea sounds like something from science-fiction, but one startup that recently emerged from stealth is trying to turn it into a reality. Lonestar Data Holdings has a unique mission unlike any other cloud provider: to build datacenters on the Moon backing up the world's data.

    "It's inconceivable to me that we are keeping our most precious assets, our knowledge and our data, on Earth, where we're setting off bombs and burning things," Christopher Stott, founder and CEO of Lonestar, told The Register. "We need to put our assets in place off our planet, where we can keep it safe."

  • Conti: Russian-backed rulers of Costa Rican hacktocracy?
    Also, Chinese IT admin jailed for deleting database, and the NSA promises no more backdoors

    In brief The notorious Russian-aligned Conti ransomware gang has upped the ante in its attack against Costa Rica, threatening to overthrow the government if it doesn't pay a $20 million ransom. 

    Costa Rican president Rodrigo Chaves said that the country is effectively at war with the gang, who in April infiltrated the government's computer systems, gaining a foothold in 27 agencies at various government levels. The US State Department has offered a $15 million reward leading to the capture of Conti's leaders, who it said have made more than $150 million from 1,000+ victims.

    Conti claimed this week that it has insiders in the Costa Rican government, the AP reported, warning that "We are determined to overthrow the government by means of a cyber attack, we have already shown you all the strength and power, you have introduced an emergency."

    The new campaign, dubbed Twisted Panda, is part of a larger, state-sponsored espionage operation that has been ongoing for several months, if not nearly a year, according to the security shop.

    In a technical analysis, the researchers detail the various malicious stages and payloads of the campaign that used sanctions-related phishing emails to attack Russian entities, which are part of the state-owned defense conglomerate Rostec Corporation.

    In a policy statement, the agency said, "Children should not have to needlessly hand over their data and forfeit their privacy in order to do their schoolwork or participate in remote learning, especially given the wide and increasing adoption of ed tech tools."

    The agency says it will scrutinize educational service providers to ensure that they are meeting their legal obligations under COPPA, the Children's Online Privacy Protection Act.

  • Mysterious firm seeks to buy majority stake in Arm China
    Chinese joint venture's ousted CEO tries to hang on - who will get control?

    The saga surrounding Arm's joint venture in China just took another intriguing turn: a mysterious firm named Lotcap Group claims it has signed a letter of intent to buy a 51 percent stake in Arm China from existing investors in the country.

    In a Chinese-language press release posted Wednesday, Lotcap said it has formed a subsidiary, Lotcap Fund, to buy a majority stake in the joint venture. However, reporting by one newspaper suggested that the investment firm still needs the approval of one significant investor to gain 51 percent control of Arm China.

    The development comes a couple of weeks after Arm China said that its former CEO, Allen Wu, was refusing once again to step down from his position, despite the company's board voting in late April to replace Wu with two co-chief executives. SoftBank Group, which owns 49 percent of the Chinese venture, has been trying to unentangle Arm China from Wu as the Japanese tech investment giant plans for an initial public offering of the British parent company.

  • SmartNICs power the cloud, are enterprise datacenters next?
    High pricing, lack of software make smartNICs a tough sell, despite offload potential

    SmartNICs have the potential to accelerate enterprise workloads, but don't expect to see them bring hyperscale-class efficiency to most datacenters anytime soon, ZK Research's Zeus Kerravala told The Register.

    SmartNICs are widely deployed in cloud and hyperscale datacenters as a means to offload input/output (I/O) intensive network, security, and storage operations from the CPU, freeing it up to run revenue generating tenant workloads. Some more advanced chips even offload the hypervisor to further separate the infrastructure management layer from the rest of the server.

    Despite relative success in the cloud and a flurry of innovation from the still-limited vendor SmartNIC ecosystem, including Mellanox (Nvidia), Intel, Marvell, and Xilinx (AMD), Kerravala argues that the use cases for enterprise datacenters are unlikely to resemble those of the major hyperscalers, at least in the near term.
