China’s biggest chipmaker SMIC seems to have been manufacturing advanced chips in the last few months — defying U.S. sanctions designed to slow down Beijing’s progress.
But there are still some major challenges to China’s bid to become more self-sufficient in the semiconductor industry, with questions swirling around the long-term viability of its latest advancements.
What’s the latest?
SMIC is China’s biggest contract semiconductor manufacturer. The nanometer figure refers to the size of each individual transistor on a chip. The smaller the transistor, the more of them can be packed onto a single semiconductor. Typically, a reduction in nanometer size can yield more powerful and efficient chips.
The 7 nanometer process is seen as highly advanced in the world of semiconductors, even though it isn’t the latest technology.
It was a big deal at the time. But last week, the Financial Times reported that SMIC is setting up new production lines to make 5 nanometer chips for Huawei. That would signal even further advancement for China’s biggest chipmaker.
The chips in Apple’s latest high-end iPhones are made on a 3 nanometer process.
Why is this a big deal?
How is SMIC doing this?
Without EUV tools, experts thought, SMIC would find it difficult to make 7 nanometer and smaller chips, or would at least find it expensive to do so.
So when the Huawei Mate 60 came out last year with a 7 nanometer chip, that raised a lot of eyebrows.
One expert told CNBC at the time that SMIC is likely using older chipmaking tools to make more advanced chips.
The FT reported something similar last week. The newspaper, citing two people with knowledge of the plans, reported that SMIC is aiming to use its existing stock of U.S.- and Dutch-made semiconductor equipment to produce 5 nanometer chips, an advancement on the 7 nanometer.
“SMIC is working very closely now with both domestic tool makers, leveraging its existing base of advanced lithography gear, and drawing on other outside expertise, such as from Huawei, to constantly improve yields on advanced node processes,” Paul Triolo, an associate partner at consulting firm Albright Stonebridge, told CNBC via email.
“So for now it is possible for SMIC to continue to improve capabilities and yields at 7 and soon 5 nm, for a small number of customers, mostly Huawei.”
China’s challenges
Using older equipment to make more advanced chips poses two major challenges.
The first is that it’s more expensive to produce the semiconductors than if more advanced tools and machinery were used. The second is an issue around yield — the number of usable chips that are produced and can be sold to customers. With older equipment, the yield is also lower.
The FT also reported, citing three people close to Chinese chip companies, that SMIC had to charge 40% to 50% more for products from its 5 nanometer and 7 nanometer production processes than TSMC does at the same nodes.
TSMC, or Taiwan Semiconductor Manufacturing Company, is the world’s largest and most advanced contract chip manufacturer. TSMC makes semiconductors for companies from Apple to Nvidia.
Pranay Kotasthane, chairperson of the high tech geopolitics program at the Takshashila Institution, told CNBC that SMIC and China could keep throwing money at the process, but ultimately, costs will continue to rise with each more advanced generation of chips — unless the company can get its hands on an ASML EUV machine.
“SMIC might overcome current yield issues by investing more money. This investment might even come from governments as this has become an issue of national prestige,” Kotasthane said via email.
“But the extent of underwriting higher costs will only increase with every subsequent generation of chips. The costs will keep compounding unless China finds a major alternative for EUVs.”

The latest version of U.S. President Donald Trump’s “big beautiful bill” could make it cheaper for semiconductor manufacturers to build plants in the U.S. as Washington continues its efforts to strengthen its domestic chip supply chain.
Under the bill, passed by the Senate Tuesday, tax credits for those semiconductor firms would rise to 35% from 25%. That’s more than the 30% increase that had made it into a draft version of the bill.
Companies eligible for the credits could include chipmakers such as Intel, Taiwan Semiconductor Manufacturing Company and Micron Technology, provided that they expand their advanced manufacturing in the U.S. ahead of a 2026 deadline.
The new provisions expand on tax incentives under the 2022 CHIPS and Science Act, which provided grants of $39 billion and loans of $75 billion for U.S.-based semiconductor manufacturing projects.
But before the expanded credits come into play, Trump’s sweeping domestic policy package will have to be passed again in the House, which narrowly passed its own version last month. The president has urged lawmakers to get the bill passed by July 4.
Trump versus Biden
Since Trump’s first term, Washington has been trying to onshore more of the advanced semiconductor supply chain from Asia, support its domestic players and limit China’s capabilities.
Although tax provisions in Trump’s sweeping policy bill expand on those in the Biden administration’s CHIPS Act, his overall approach to the semiconductor industry has been different.
Earlier this year, the president even called for a repeal of the CHIPS Act, though Republican lawmakers have been reluctant to act on that front. Still, U.S. Commerce Secretary Howard Lutnick said last month that the administration was renegotiating some of the Biden administration’s grants.
Trump has previously stated that tariffs, as opposed to the CHIPS Act grants, would be the best method of onshoring semiconductor production. The Trump administration is currently conducting an investigation into imports of semiconductor technology, which could result in new duties on the industry.
In recent months, a number of chipmakers with projects in the U.S. have ramped up planned investments there. That includes the world’s largest contract chipmaker, TSMC, as well as American chip companies such as Nvidia, Micron and GlobalFoundries.
According to Daniel Newman, CEO at tech advisory firm Futurum Group, the threat of Trump’s tariffs has created more urgency for semiconductor companies to expand U.S. capacity. If the increased investment tax credits come into law, those onshoring efforts are only expected to accelerate, he told CNBC.
“Given the risk of tariffs, increasing manufacturing in the U.S. remains a key consideration for these large semiconductor companies,” Newman said, adding that the tax credits could be seen as an opportunity to offset certain costs related to U.S.-based projects.

Tesla shares have dropped 7% from Friday’s closing price of $323.63 to the $300.71 close on Tuesday ahead of the company’s second-quarter deliveries report.
Wall Street analysts are expecting Tesla to report deliveries of around 387,000 — a 13% decline compared to deliveries of nearly 444,000 a year ago, according to a consensus compiled by FactSet. Prediction market Kalshi told CNBC on Tuesday that its traders forecast deliveries of around 364,000.
Shares in the electric vehicle maker had been rising after Tesla started a limited robotaxi service in Austin, Texas, in late June and CEO Elon Musk boasted of its first “driverless delivery” of a car to a customer there.
The stock price took a turn after Musk on Saturday reignited a feud with President Donald Trump over the One Big Beautiful Bill Act, the massive spending bill that the commander-in-chief endorsed. The bill is now heading for a final vote in the House.
That legislation would benefit higher-income households in the U.S. while slashing spending on programs such as Medicaid and food assistance.
Musk did not object to cuts to those specific programs. However, Musk on X said the bill would worsen the U.S. deficit and raise the debt ceiling. The bill includes tax cuts that would add around $3 trillion to the national debt over the next decade, according to an analysis by the Congressional Budget Office.
The Tesla CEO has also criticized aspects of the bill that would cut hundreds of billions of dollars in support for renewable energy development in the U.S. and phase out tax credits for electric vehicles.
Such changes could hurt Tesla as they are expected to lower EV sales by roughly 100,000 vehicles per year by 2035, according to think tank Energy Innovation.
The bill is also expected to reduce renewable energy development by more than 350 cumulative gigawatts in that same time period, according to Energy Innovation. That could pressure Tesla’s Energy division, which sells solar and battery energy storage systems to utilities and other clean energy project developers.
Trump told reporters at the White House on Tuesday that Musk was, “upset that he’s losing his EV mandate,” but that the tech CEO could “lose a lot more than that.” Trump was alluding to the subsidies, incentives and contracts that Musk’s many businesses have relied on.
SpaceX has received over $22 billion from work with the federal government since 2008, according to FedScout, which does federal spending and government contract research. That includes contracts from NASA, the U.S. Air Force and Space Force, among others.
Tesla has reported $11.8 billion in sales of “automotive regulatory credits,” or environmental credits, since 2015, according to an evaluation of the EV maker’s financial filings by Geoff Orazem, CEO of FedScout.
These incentives are largely derived from federal and state regulations in the U.S. that require automakers to sell some number of low-emission vehicles or buy credits from companies like Tesla, which often have an excess.
Regulatory credit sales go straight to Tesla’s bottom line. Credit revenue amounted to approximately 60% of Tesla’s net income in the second quarter of 2024.

Amazon founder Jeff Bezos unloaded more than 3.3 million shares of his company in a sale valued at roughly $736.7 million, according to a financial filing on Tuesday.
The stock sale is part of a previously arranged trading plan adopted by Bezos in March. Under that arrangement, Bezos plans to sell up to 25 million shares of Amazon over a period ending May 29, 2026.
Bezos, who stepped down as Amazon’s CEO in 2021 but remains chairman, has been selling stock in the company at a regular clip in recent years, though he’s still the largest individual shareholder. He adopted a similar trading plan in February 2024 to sell up to 50 million shares of Amazon stock through late January of this year.
Bezos previously said he’d sell about $1 billion in Amazon stock each year to fund his space exploration company, Blue Origin. He’s also donated shares to Day 1 Academies, his nonprofit that’s building a chain of Montessori-inspired preschools across several states.
The most recent stock sale comes after Bezos and Lauren Sanchez tied the knot last week in a lavish wedding in Venice. The star-studded celebration, which took place over three days and sparked protests from some local residents, was estimated to cost around $50 million.
Bezos is ranked third in Bloomberg’s Billionaires Index with a net worth of about $240 billion. He’s behind Tesla CEO Elon Musk at $363 billion and Meta CEO Mark Zuckerberg at $260 billion.
