Accused of Stealing Chip Tech in the US, Now Thriving in China

Few companies are better positioned to benefit from the crippling shortage of computer chips than ASML Holding NV, a Dutch manufacturer whose equipment plays an integral role in making the world’s most advanced semiconductors.

But four lines tucked halfway into an otherwise upbeat, 281-page annual report from February hinted at a potentially incendiary problem. ASML accused a Beijing-based firm, regarded by Chinese officials as one of the country’s most promising tech ventures, of potentially stealing its trade secrets. Behind the brief disclosure is an extraordinary multiyear tale of intellectual property theft and a broader threat facing the $556 billion semiconductor industry.

In the report, ASML said the Chinese company, Dongfang Jingyuan Electron Ltd., is related to a defunct Silicon Valley firm, Xtal Inc., which ASML sued for intellectual property theft.

A 2018 trial in California, which received scant attention at the time, provided more detail. Dongfang and Xtal were essentially the same, created a month apart in 2014 by a former ASML engineer named Zongchang Yu, ASML’s attorney told the court. The two companies worked in tandem toward the same goal: obtaining ASML’s technology and transferring it to China, which is seeking to foster its semiconductor industry, often at the expense of Western companies, the attorney argued.

That technology was secured in a sometimes audacious fashion: one engineer was accused of stealing all 2 million lines of source code for critical ASML software and then sharing part of it with Xtal and Dongfang employees in the US and China, according to transcripts of the proceedings.

“It’s not an accident. It’s not anything else,” Patrick Ryan, ASML’s lead attorney, told the court. “But it is a plot to get technology for the Chinese government.”

Xtal lost and filed for bankruptcy protection. It was ordered to pay $845 million, which ASML deemed “uncollectable.”

ASML declined to comment on this story. A Dongfang representative declined to comment. Yu, 60, who has an outstanding arrest warrant in California on allegations of stealing trade secrets from ASML, couldn’t be reached for comment. He now runs Dongfang in Beijing with ample support from the Chinese government, according to company statements and other Chinese documents.

The allegations the company made in court and its annual report reflect the delicate position ASML finds itself in, trying to grow its business in China while pursuing claims of IP theft against a Chinese company.
China is the world’s largest market for semiconductors. Its electronics factories and growing middle class are vital consumers of chips. Semiconductor companies have struggled for years to balance access to China against concerns the country is seeking to pilfer their intellectual property and overtake them.

For now, China lags in semiconductor manufacturing, leaving its most important industries dependent on technology dominated by foreign companies. Making its advanced chips is a priority that’s complicated by US sanctions that limit access to the latest equipment. Beijing has taken unprecedented steps to clear such hurdles, including launching a $150 billion semiconductor initiative in 2014 to turbocharge domestic production.

According to the FBI, China has also encouraged people to steal technology that advances Beijing’s interests. “China recognizes it needs to make leaps in cutting-edge technologies,” FBI Director Christopher Wray said. “Instead of engaging in the hard slog of innovation, China often steals American intellectual property and then uses it to compete against the very American companies it victimized.”

ASML’s allegations offer a detailed example of what national security authorities describe as China’s playbook to acquire advanced technology. It’s a set of strategies, they say, that depends on inducements from Beijing, theft by well-placed workers, and in at least some cases, a reluctance to complain by corporate victims seeking to preserve or enhance access to the Chinese market.

“Taken individually these cases can seem anecdotal, and some victim companies might say there’s not any master plan,” said Anna Puglisi, a senior fellow at the Center for Security and Emerging Technology at Georgetown University. “But take this together with other cases over time and you can see the silent—and in some cases not so silent t—the hand of the Chinese government.”

China’s Ministry of Foreign Affairs called the allegations “malicious hype.” “Anti-China politicians in the US have been using ‘IP theft’ topics to tarnish China,” the ministry said in a statement. “China didn’t make its technology achievements by stealing or robbing from others.”

Veldhoven, Netherlands-based ASML makes technology that’s crucial for manufacturing the fastest, most powerful computer chips. According to research firm Gartner Inc., as of 2021, ASML controlled more than 90% of the $17.1 billion global markets for lithography equipment, which is used to shrink and then print patterns of transistors onto silicon wafers that are then sliced into individual chips.

A single machine can be the size of a small house and cost roughly $170 million. That technology is why the company’s market capitalization has more than quadrupled in four years, to $284 billion at the end of 2021.

At the centre of the litigation is a software called optical proximity correction, or OPC. It makes up less than 1% of ASML’s revenue. But without it, lithography machines can’t accurately print tiny circuits, according to trial testimony.

“If you didn’t do any OPC, then the pattern on the chip is scummed,” testified Yu Cao, an ASML executive who was the general manager of the division that develops the software. “This would be a chip that doesn’t work.”

China is developing its lithography machines, but it could take years to catch up to ASML, if ever, according to Robert Castellano, president of The Information Network, a Pennsylvania-based semiconductor research firm. Mastering OPC software could close some of the gaps by allowing Chinese manufacturers to improve those machines and pack more transistors onto the chips they produce, he said.

That leap could have implications beyond consumer devices. “This is not about making a better smartphone,” Castellano said. “It’s about making weapons that are more sophisticated than they are right now.”

The year 2014 was important for China’s semiconductor ambitions. That’s when the country created its $150 billion funds to jumpstart companies to compete with foreign behemoths.

It’s also when Yu started his two companies. Educated in China, he had worked mostly in Japan and the US, including at ASML, which he left in 2012, according to court documents. In January 2014, he incorporated Xtal, based in an office park near San Jose International Airport. A month later, he founded Dongfang, a government-funded industrial enclave in Beijing.

You created the companies at the direction of Jingyuan Han, a member of China’s economic elite who retains close ties to the Communist Party, Ryan, ASML’s attorney, alleged in court. Han serves as chairman and chief executive officer of China Oriental Group Co., a large steel producer, where his biography lists multiple Communist Party roles.

The goal was to tap into incentive programs while delivering critical technologies for China’s semiconductor initiative, Ryan alleged.

Despite its industrial-age specialization, China Oriental is a player in the country’s race to become a global technology superpower, often through investments by the company or by Han personally, according to corporate filings and Ryan’s courtroom arguments. Until 2019, China Oriental, through subsidiaries, owned more than 50% of Dongfang, according to Datenna, a Dutch firm that tracks the ownership of Chinese companies. It has since sold its stake as other investors have come on board, Datenna said.

Representatives for China Oriental didn’t return messages seeking comment.

As trial testimony alleged, Yu recruited engineers from the ASML division where they worked developing OPC software, and the departing employees assured their managers they would be working on unrelated technologies.

But after Song Lan, director of engineering, resigned in August 2015, ASML examined his computer. Investigators found he was working for both companies at the same time and had downloaded ASML files to a hard drive that he took to his new employer, according to a filing by the Dutch company in Xtal’s bankruptcy proceedings. The company said it found similar violations involving others who left for Xtal.

After Xtal began marketing OPC software, ASML sued.
The data were taken by Lan, who became Xtal’s vice president of engineering and included source code for ASML’s OPC software, according to the filing. Lan testified that he took the code inadvertently while backing up his ASML email to preserve personal data. The code was in a file attached to an email that Lan said he never opened.

ASML’s attorneys said they weren’t able to learn the full scope of Lan’s activities. After ASML informed Xtal of its intent to sue, Lan used a wiper program on the hard drive and erased as much as 61 gigabytes of data, according to the filing. Lan didn’t address the deletion in his testimony, as Xtal’s attorneys objected to a question about it.

Another former employee, Wanyu Li, who became Xtal’s IT director, downloaded the source code for ASML’s OPC software—all 2 million lines of it—to a hard drive, according to testimony from ASML forensic experts. Investigators found evidence that Li used it immediately at Xtal, uploading part of the code to a GitHub server where it was accessible to about 30 engineers with Xtal and Dongfang, according to the testimony.

The judge informed the jury that Li admitted to destroying evidence, breaking the hard drive’s circuit board into pieces before turning it over to Xtal’s attorneys on the eve of trial, according to trial transcripts.

Xtal’s attorney, Donald Putterman, acknowledged that Li stole the source code and damaged the hard drive. “There’s no sugarcoating with what Wanyu Li did,” Putterman told the court. “You can’t do it. It was wrong. It was illegal. Off the charts.”

However, he said no one at Xtal knew that Li had the stolen code. “It was never actually used by Xtal,” he said. “Xtal never made a penny on it.”

ASML attorneys referred the case to Santa Clara County’s District Attorney’s Office, which filed criminal charges in April 2019 alleging theft of trade secrets against Yu, Li and Lan, according to court documents.

Li, 56, pleaded guilty to a felony charge and Lan, 48, to a misdemeanour charge, both for taking computer data, according to prosecutor Erin West. Li was sentenced to seven months of electronic monitoring, and Lan to 90 days of community service, she said.

Both men, through their attorneys, declined to comment. When authorities went to arrest the three men in May 2019, Yu had left for China, West said.

ASML’s attorneys accused Yu of orchestrating the thefts. Yu was on emails where his employees discussed using the Dutch company’s source code to help speed up Xtal’s software development, according to testimony from ASML’s forensic experts. He also had copies of confidential ASML technical manuals and emailed them to his staff, they testified.

Yu testified that at the time he didn’t believe there was a problem using some internal ASML materials to help guide Xtal’s work.

“It is s a very good reference for oumodellingng work,” Yu wrote in one email.

By using stolen data as a roadmap, Xtal shaved years off the time needed to develop the software, Ryan argued.

In January 2016, Xtal won a $27 million contract with South Korea’s Samsung Electronics Co., a longtime ASML customer, to supply OPC software, according to trial testimony. In two years, Yu’s company had replicated a technology that ASML said it had spent $100 million and 10 years developing.

“Xtal didn’t have to go down dead ends, because it knew which ones were dead ends, and it knew which ones were the path to glory, the path to speed, the development path, the path to the money,” Ryan told the jury.

Samsung said it doesn’t have a current relationship with Xtal or Dongfang. The company pointed to a statement by ASML saying that Samsung wasn’t involved in “any malicious actions against ASML.” The Dutch company didn’t lose any business because the work between Samsung and Xtal was “thwarted” when the theft was discovered, according to the statement.

After ASML’s court victory a Dutch newspaper Het Financieele Dagblad published a report alleging a link between the thefts and China. ASML refuted it and offered a different motive that didn’t involve China. “The wide speculation about a government-directed ‘conspiracy’ to steal our IP and trade secrets is therefore just that: wide speculation,” ASML said, in an April 2019 press release.

Chief Executive Officer Peter Wennink reiterated that position. “The suggestion that we were somehow a victim of a national conspiracy is wrong.”

“The facts of the matter are that we were robbed by a handful of our employees based in Silicon Valley who had broken the law to enrich themselves,” he said.
“The suggestion that we were somehow w victim of a national conspiracy is wrong” — ASML CEO Peter Wennink

However, months earlier, ASML’n attorneys had directly linked Yu’s companies to China’s technology ambitions. “It’s consistent with a broader strategy that is being employed by the Chinese government,” Andrew Winetroub, an ASML attorney, told the court. ASML had evidence, he argued, that Dongfang was receiving funds from the Chinese government and that “Xtal is intimately involved.”

“They want to essentially be ASML in China,” Ryan, the lead ASML attorney, argued. “Stealing our software was a step in the right direction.”
ASML sought to introduce evidence that its lawyers said would support those claims. Putterman, Xtal’s attorney, argued that it amounted to “repetitive efforts” to “back-door prejudicial intonation” about China. The judge instructed ASML to focus on allegations limited to the US company, Xtal.

ASML’s case highlights the complications many Western companies facing dealing with China.

China is ASML’s third-biggest market. Since 2019, the Dutch government has prevented the company from selling its most advanced lithography equipment there because the chips the equipment makes have potential military uses. ASML has opposed the restrictions.

Nick Eftimiades, a senior fellow at the Atlantic Council, said China “put ASML in an extraordinarily awkward position.”

“This isn’t the first time that a company’s been stolen from and refused to make it a big issue publicly,” said Eftimiades, a former US Department of Defense official who tracks Chinese IP theft and espionage cases. “Many companies go to extraordinary lengths to keep these events from being known to the public, stockholders and investors.”

For Yu, Xtal’s troubles did little to slow Dongfang’s ascent.

In 2015, Dongfang signed a research agreement with the Institute of Microelectronics of the Chinese Academy of Sciences, the government’s semiconductor research centre, according to Chinese documents. There, Yu caught the attention of Tianchun Ye, the institute’s director and the chief scientist directing China’s chip equipment development. Dongfang and the institute created a joint venture for chip technology development. Since then, Dongfang has won repeated honoursrs and praise from the Chinese government.

Despite losing the Xtal case, Chinese authorities granted Dongfang a wide-ranging patent in 2019 that includes OPC software. Last year, Dongfang announced that it was named a “little giant” by China’s Ministry of Industry and Information Technology, a designation often followed by significant new investment and expectations of rapid growth.

Since returning to Beijing, Yu has raised millions of dollars while being courted by Chinese officials. He appeared on the reviewing stand for a military parade marking the 70th anniversary of China’s founding—an invitation-only affair reserved for elites.

A 2020 book of interviews with Chinese tech entrepreneurs portrayed Yu as a “flagbearer” for semiconductor development. He told the authors one of his biggest dreams was to help China create OPC software—and “break the foreign monopoly.”
