Shockingly, a counterfeit factory has produced a 3-nanometer chip.

Chapter 487 New "Open Source" Plans

Half an hour later, the two arrived at Shen Fei's house.

After listening briefly to Zhou Mingyuan's report, he did not immediately express his opinion, but instead called Li Jiahui over first.

So the four of them held a brief meeting.

"Li Jae-yong has just taken office and needs a victory to establish his authority."

After listening, Li Jiahui finally understood the current situation.

Zhou Mingyuan nodded, since that was roughly the idea.

"According to our investigation, the panel lawsuit had its own backers, but it was lost."

So he wanted to make up for it in semiconductors.

Shen Fei said another sentence...

"TSMC is also panicking. Their 22nm yield rate has indeed improved, but our foundry prices have also decreased. Currently, we are only 2% more expensive than them..."

In fact, the difference is very small, and quite a few core clients have already been contacting us to switch orders.

It's normal for the two of them to team up.

Yuan Guoqing frowned and pushed the report back to him.

"Should we refuse outright and then strengthen internal security?"

After all, they're targeting our quadruple exposure technology, which...this is our core technology, and the risk of it being leaked is too great.

All three nodded subconsciously.

"If you refuse this time, there will be a next time."

They're still up to no good and will always find other ways. Instead of passively defending ourselves, we should proactively set a trap and teach them a lesson they won't forget.

"How can we turn the tables on them? We've thought about this a lot, but the risk of technology leakage is just too great."

"It's nothing!" Shen Fei looked at Zhou Mingyuan, but all three of them saw a hint of amusement in Shen Fei's eyes.

"Mingyuan, this time you'll have to work hard to act in a play."

We gave them a set of technologies—technologies that could only run on our production line, and would cause major problems if implemented on theirs.

Yuan Guoqing immediately replied, "That's easy."

I think we can use a yield optimization algorithm.

Currently, this technology is a customized calibration that is deeply integrated with a self-developed lithography control system, domestically produced photoresist, and photomask, much like a tailor-made garment.

If we modify this algorithm, remove the adaptation verification module, and put it on SanSang's production line...

They are now using the original Asmail control system, combined with Japanese materials.

I can guarantee that there won't be any major problems in the initial stage of the process, and it may even temporarily improve the yield rate. However, after running for a period of time, the cumulative error of the optical parameters will become larger and larger.

This ultimately led to a drift in overlay accuracy, causing the entire wafer to explode.

In severe cases, it can even damage the projection lens of the lithography machine.

"That's definitely a good idea!"

All four of them showed a hint of blessing for San Sang, but Shen Fei thought about it again.

This is a serious technical glitch!

"Director Yuan, based on your experience, how long would it take to fix this problem? I need an accurate figure," Shen Fei said.

"If the core problem cannot be found, it will take at least 6 months to resume production by only checking the equipment and replacing the materials."

If the equipment is truly completely damaged, it will take at least a year and a half.

Yuan Guoqing had already started laughing, and the other two had also started clapping.

"As for whether it will be cracked? We have encrypted and obfuscated this algorithm. Even if they want to reverse engineer it, it will take them a year or two to figure out the underlying logic."

By the time they figure it out, their chip production lines will be long gone.

Li Jiahui was also shocked upon hearing this.

This move was undeniably ruthless; it not only caused Sansang to suffer heavy losses but also stole their customers, achieving two goals at once.

Zhou Mingyuan immediately understood that to make this plan succeed, he had to show enough sincerity.

"Mr. Shen, I understand what to do."

First, pretend to be interested and negotiate with them. Then, release some peripheral parameters to let them verify the effects. Finally, slowly reveal some core technology to dispel their doubts.

"it is good."

Shen Fei slammed his hand on the table, agreeing to the plan.

"The three of you will take the lead on this matter, and the technical team will work overnight to develop a solution to ensure everything goes smoothly."

"Mingyuan, please be careful and keep us updated on the situation. I will award you a first-class merit after this is done."

After the discussion, Shen Fei returned to his bed, but as soon as he got into bed, he found Zhang Mingzhu, who had been sleeping, looking at him with a worried expression.

"What's wrong? Did the Americans make another move? Is that why you're so anxious?"

She thought something had happened in England again.

Shen Fei gently rubbed his head: "Don't worry, it's nothing serious!"

"Someone is going to be in trouble, and your man knows it."

"good!"

After saying that, Zhang Mingzhu blushed and whispered something in his ear, and then... the entire room instantly...

The next morning, Shen Fei returned to his office with dark circles under his eyes.

The prepared plan was already laid out on the desk.

For the next two weeks, Zhou Mingyuan acted flawlessly. He first pretended to hesitate, saying the risks were too great and he was afraid of being held accountable by the telepathic communication.

But after repeated persuasion from the headhunter, he gradually began to relent.

Since it was their first collaboration, regardless of the technology involved, the other party was willing to offer a deposit of 2000 million yuan to express their sincerity.

This completely sheds the meagerness of the cooperation with South Korea, after all, this is enough to buy a quarter of a MStar series lithography machine.

So Zhou Mingyuan released a set of edge environment calibration parameters.

After receiving the technology, Sansang immediately tested it on the experimental production line. This technology can be used not only on 22nm but also on 20nm.

Most importantly, after a week of testing, the yield rate actually increased by four percentage points.

This completely convinced the technical team at SanSang Semiconductor.

They originally believed that Transsion's mulberry yield optimization relied on algorithm tuning, which had a high technical barrier.

Now that the parameters have been verified to be effective, I am even more convinced.

After receiving feedback, the headhunter knocked on Lee Jae-yong's office door again.

"Boss, after testing and debugging on the test line, we have confirmed that the algorithm is effective and is expected to save us 20 billion yuan every year!"

We request further infiltration!

"Is that really the case?" Lee Jae-yong stared intently at him, and just as the other was about to answer, he said again, "No, it might just be a smokescreen."

Perhaps their algorithm is causing some hidden harm to our production line?

Test it a few more times!

"The boss has already tested it on the test line and it can improve by 4%... If we adapt it, it might be even higher, but our engineers can't figure out this algorithm yet."

Don't worry, as long as more funding is approved, I can definitely take down Zhou Mingyuan.

After all, the other party has already become an internal spy, and once they've embarked on this path, there's no turning back.

Although Lee Jae-yong's expression didn't change, he understood perfectly, and in just a second, he made his final decision.

"I'll give you the maximum authority. As long as you can secure the four-layer exposure technology within 20 billion, I won't hold you accountable; on the contrary, I'll praise you highly!"
