The semiconductor shortage that affected everything from cars to games consoles during the height of the Covid-19 pandemic has turned into a chip glut — and some of the world’s biggest chipmakers are taking a hit.

Semiconductors are tiny components that are integral to a slew of products including refrigerators, cars, smartphones and LED bulbs.

The Covid-19 pandemic caused huge disruption in the supply chains and production of chips, as consumers stuck at home went mad for products like PCs and smartphones.

This boosted demand for semiconductors such as the memory chips made by South Korean firms Samsung, SK Hynix and Micron.

There was also increased demand for less-advanced chips required for processes like power management in devices.

It led to a widespread shortage of products such as games consoles and even components for washing machines, which continued through the first half of 2022. There was also a lack of semiconductors that go into cars, leading to a drop in the production of vehicles from major automakers.

While the supply and demand dynamics for some chips have since become more balanced, in other areas, the chip shortage has turned into a glut.

Memory chip oversupply

Two types of chips are in oversupply right now: NAND and DRAM memory. These go into devices like laptops and also servers in data centers.

The glut came after companies began to stockpile chips amid the shortage to build up inventories.

But then the economy slowed down.

Demand for products like smartphones and laptops has dropped off in a big way — particularly as many people bought them during the pandemic.

“So, the makers of these end products stopped ordering chips and instead focused on selling through the inventory they already had,” Peter Hanbury, partner in the telecoms, media and technology practice at Bain & Company, told CNBC.

“This led to a strong ‘bullwhip’ effect for the semiconductor markers further back in the supply chain where sky high demand during the chip shortage suddenly dried up as end markets stopped ordering chips and instead focused on selling through the inventory they already had.”

Not all types of semiconductors are in oversupply, however, with demand for chips from the auto sector remaining strong.

Hanbury said that some chips made for specific purposes are not easy to exchange for other semiconductors, and so “their lead times and prices are improving but remain quite high.”

From profit boost to income plunge

The pandemic-induced shortage of semiconductors helped boost chip makers’ profits as prices jumped. This included Samsung, the world’s largest memory chip manufacturer.

This year, however, Samsung and its rivals SK Hynix and Micron, have had a tough time.

Samsung on Thursday said operating profit for the second quarter plunged 95% year-on-year. Meanwhile, SK Hynix swung to a loss in the second quarter versus a profit in the same period last year.

Taiwan Semiconductor Manufacturing Company, the world’s largest chipmaker, said last week that net income for the second quarter fell 23.3% from a year ago. It was its first quarterly profit decline in 4 years.

Looking ahead, the PC market appears weak, which is likely to impact Samsung, SK Hynix and Micron.

For TSMC, the global smartphone market — a major revenue driver — is also under pressure.

“The smartphone market is still the biggest part of TSMC’s revenue. That part is still not seeing any meaningful pick up,” Sze Ho Ng, an analyst at China Renaissance Securities, told CNBC via phone.

Chip balance soon?

In an effort to boost the price of chips and reduce supply in the market, the major memory chip firms have announced production cuts.

Samsung said it expects global demand to recover in the second half of the year, and others have echoed a similar sentiment.

TSMC, however, said last week that it expects “continued inventory adjustment” from customers.

“After this year’s correction, I think there will be a second-half growth scenario for TSCM, but how strong that will be will be dependent on the macro environment,” Ng said.

Ultimately, recovery for these firms will depend on whether demand picks up for end products like consumer electronics, but that’s related to a macroeconomic recovery which looks far from certain.

India is betting  billion to build a chip powerhouse. Here’s what it means

India wants to become a global chip major, but the odds are steep: competition is fierce, and India is a late entrant in the race to make the most advanced chips.

In 2022, when the U.S. restricted exports of its advanced AI chips to China to curb Beijing’s access to cutting-edge technology, a global race for semiconductor self-reliance began.

For India, it offered an opportunity: the country wants to reduce dependence on imports, secure chips for strategic sectors, and capture a bigger share of the global electronics market shifting away from China.

India is one of the world’s largest consumers of electronics, but it has no local chip industry and plays a minimal role in the global supply chain. New Delhi’s “Semiconductor Mission” aims to change that.

The ambition is bold. It wants to create a full supply chain — from design to fabrication, testing and packaging — on Indian soil.

As of this month, the country has approved 10 semiconductor projects with total investment of 1.6 trillion rupees ($18.2 billion). These include two semiconductor fabrication plants, and multiple testing and packing factories.

India also has a pool of engineering talent that is already employed by global chip design companies.

Yet progress so far has been uneven, and neither the investments nor talent pool is enough to make India’s chip ambitions a reality, say experts.

“India needs more than a few fabs or ATP facilities (i.e., more than a few “shiny objects.”) It needs a dynamic and deep and long-term ecosystem,” said Stephen Ezell, vice president for global innovation policy at the Information Technology and Innovation Foundation, a science and technology policy think tank.

Ezell says that leading semiconductor manufacturers consider “as many as 500 discrete factors” before they set up multi-billion-dollar fab investments. These include talent, tax, trade, technology policies, labor rates and laws and customs policies — all areas where India has work to do.

New Delhi’s policy push

In May, the Indian government added a new element to its chip ambition: a scheme to support electronic component manufacturing, addressing a critical bottleneck.

Until now, chipmakers had no local demand for their product as there are hardly any electronic component manufacturing companies, such as phone camera companies, in India.

But the new policy offers financial support to companies producing active and passive electronic components, creating a potential domestic buyer-supplier base that chip manufacturers can plug into.

In 2022, the country also pivoted from its strategy of providing superior incentives to fabrication units making chips of 28nm or less. When it comes to chips, the smaller the size, the higher the performance with improved energy efficiency. These chips can be used in new technologies like advanced AI and quantum computing by packing more transistors into the same space.

But this approach wasn’t helping India develop its nascent semiconductor industry, so New Delhi now covers 50% of the project costs of all fabrication units, regardless of chip size, and of chip testing and packing units.

Fab companies from Taiwan and the U.K., and semiconductor packaging companies from the U.S. and South Korea have all shown interest in aiding India’s semiconductor ambitions.

“The Indian government has doled out generous incentives to attract semiconductor manufacturers to India,” said Ezell, but he stressed that “those sorts of investments aren’t sustainable forever.”

The long road

The biggest chip project in India currently is the 910-billion-rupee ($11 billion) semiconductor fabrication plant being built in Prime Minister Narendra Modi’s home state of Gujarat by Tata Electronics, in partnership with Taiwan’s Powerchip Semiconductor Manufacturing Corp.

The unit will make chips for power management integrated circuits, display drivers, microcontrollers and high-performance computing logic, Tata Electronics said, which can be used in AI, automotive, computing and data storage industries.

The U.K.’s Clas-SiC Wafer Fab has also tied up with India’s SiCSem to set up the country’s first commercial compound fab in the eastern state of Odisha.

These compound semiconductors can be used in missiles, defence equipment, electric vehicles, consumer appliances and solar power inverters, according to a government press release.

“The coming 3-4 years is pivotal for advancing India’s semiconductor goals,” said Sujay Shetty, managing director of semiconductor at PwC India.

Establishing operational silicon fabrication facilities and overcoming technical and infrastructural hurdles that extend beyond incentives will be a key milestone, according to Shetty.

Opportunities beyond fab

Last week, Indian minister Ashwini Vaishnaw, who was in Bengaluru to inaugurate a new office of semiconductor design firm ARM, said the British company will design the “most advanced chips used in AI servers, drones, mobile phone chips of 2 nm” from the south Indian city.

But experts say the role of local talent is likely to be limited to non-core design testing and validation, as the core intellectual property for chip designs is often held in locations like the U.S. or Singapore, where established IP regimes support such activities.

“India has sufficient talent in design space, because unlike semiconductor manufacturing and testing that has come up in the last 2 years, design has been there since 1990s,” said Jayanth BR, a recruiter with over 15 years of experience in hiring for global semiconductor companies in India.

He said global companies usually outsource “block-level” design validation work to India.

Going beyond this is something India’s government will need to solve if it wants to fulfil its semiconductor ambitions.

“India may consider updating its IP laws to address new forms of IP, like digital content and software. Of course, improving enforcement mechanisms will go a long way in protecting IP rights,” says Sajai Singh, a partner at Mumbai-based JSA Advocates & Solicitors.

“Our competition is with countries like the U.S., Europe, and Taiwan, which not only have strong IP laws, but also a more established ecosystem for chip design.”

'We need the smartest people': Nvidia, OpenAI CEOs react to Trump's H-1B visa fee

Nvidia CEO Jensen Huang and OpenAI CEO Sam Altman on Monday commented on President Donald Trump’s decision to increase the cost of hiring overseas workers on visas.

Trump on Friday announced that he would raise the fee for an H-1B visa to $100,000, leaving companies scrambling. Employers now must have documentation of the payment prior to filing an H-1B petition on behalf of a worker. Applicants will have their petitions restricted for 12 months until the payment is made, according to the White House.

Huang and Altman responded to the changes in an interview with CNBC’s Jon Fortt, where the two executives announced that Nvidia will invest $100 billion in OpenAI as the artificial intelligence lab sets out to build hundreds of billions of dollars-worth of data centers based around the chipmaker’s AI processors.

“We want all the brightest minds to come to the U.S. and remember immigration is the foundation of the American Dream,” Huang said Monday. “We represent the American Dream. And so I think immigration is really important to our company and is really important to our nation’s future, and I’m glad to see President Trump making the moves he’s making.”

OpenAI CEO Sam Altman also expressed a positive outlook on Trump’s changes.

“We need to get the smartest people in the country, and streamlining that process and also sort of outlining financial incentives seems good to me,” Altman said.

The new $100,000 fee would be a seismic shift for U.S. technology and finance sectors, which rely on the H-1B program for highly skilled immigrants, particularly from India and China. Those two countries accounted for 71% and 11.7% of visa holders last year, respectively.

Those who already have H-1B visas and are located outside the U.S. will not be required to pay the fee in order to re-enter. Many employers use H-1B workers to fill the gaps in these highly technical roles that are not found within the American labor supply.

Here's everything Trump is changing with H-1B visas

President Donald Trump raised the fee for an H-1B visa to $100,000 on Friday, leaving companies scrambling to respond.

With many left wondering whether their careers will remain in tact, here’s a breakdown of the new H-1B fees:

What did Trump change?

As of Sunday, H-1B visa applications will require a $100,000 payment. Previously, visa fees ranged from $2,000 to $5,000 per application, depending on the size of the company.

Employers now must have documentation of the payment prior to filing an H-1B petition on behalf of a worker. Applicants will have their petitions restricted for 12 months until the payment is made, according to the White House.

Who does this impact?

The fee will only be applied to new H-1B applicants, not renewals or current visa holders, according to White House press secretary Karoline Leavitt. The fee will be implemented in the upcoming lottery cycle.

Those who already have H-1B visas and are located outside the U.S. will not be required to pay the fee in order to re-enter.

Leavitt also clarified that the $100,000 is a one-time payment and not an annual charge.

Exceptions can be made to any immigrant whose employment is deemed essential in the national interest by the Secretary of Homeland Security and does not pose a threat to the security or welfare of the U.S.

Employees with B visas who have start dates prior to October 2026 will also receive additional guidance in order to prevent using those temporary business visas as a workaround for H-1B visas.

Who are these workers and why are they needed?

H-1B visas allows highly skilled foreign professionals to work in specialty occupations that generally require at least a bachelor’s degree to fulfill the role. Jobs in the fields of science, technology, engineering and math, or STEM, usually qualify.

Many employers use H-1B workers to fill the gaps in these highly technical roles that are not found within the American labor supply.

Companies in the tech and finance sectors rely heavily on these specially-skilled immigrants, particularly from India and China, which accounted for 71% and 11.7% of visa holders last year, respectively.

How many H-1B visas does the tech industry use every year?

The current annual cap for H-1B visas is 65,000, along with an additional 20,000 visas for foreign professionals with a master’s degree or doctorate from a U.S. institution. A lottery system is used to select additional petitions if demand exceeds the cap.

Since 2012, about 60% or more of approved H-1B workers had computer-related jobs, according to Pew Research.

Amazon was the top employer for H-1B holders in the fiscal year 2025, sponsoring over 10,000 applicants by the end of June, according to U.S. Citizenship and Immigration Services. Microsoft and Meta had over 5,000 each, while Apple and Google rounded out the top six with over 4,000 approvals.
