Luo Jia drove to SMIC, and on a cold day, Tang Boyun's secretary was already waiting.

After the doorman went through the formalities, Luo Jia and Zhang Dongning came to Mr. Tang's office.

Tang Boyun and Luo Jia are already old friends, and after a little greeting, Luo Jia went directly to the topic, asked Zhang Dongning to take out the sample, and explained the technical indicators.

Tang Boyun was relaxed at first, listening quietly, and nodding lightly.

However, after he had listened to it all, he showed a look of extreme shock, and his wrist couldn't help but tremble.

"You're saying you made a photoresist for a semiconductor factory!?" Tang Boyun's eyes lit up, the whole person stood up, and asked in a hoarse voice.

Photoresists are graded into six grades based on their quality.

SMIC is the world's fourth-largest semiconductor foundry after TSMC, GLOBALFOUNDRIES, and Taiwan UMC.

The so-called foundry means that SMIC itself does not have its own semiconductor brand, but after Huawei HiSilicon, Spreadtrum, these semiconductor design companies, complete the chip design, SMIC manufactures it for them.

Super semiconductor giants like Samsung and Intel, of course, also have huge factories, but they mainly make products for themselves, and they don't have much time to process for others.

Especially Intel, they have almost no foundry business, Samsung at least makes Snapdragon series mobile phone processors for Qualcomm, and Intel's factory, just manufacturing its own CPU, has almost occupied the production capacity.

In short, in the field of semiconductor foundry, there is a super company, and that is TSMC.

AMD's CPU, NVIDIA's display chips, and Kirin's Snapdragon processors are all handled by TSMC.

Under TSMC, GLOBALFOUNDRIES used to be AMD's semiconductor manufacturing department, which was strong, and with the addition of TSMC and SMIC, it was known as the top three.

IT CAN BE SEEN THAT SMIC IS BY NO MEANS PLAYING THE ROLE OF SOY SAUCE IN THE SEMICONDUCTOR FIELD, THEY ARE ONE OF THE TOP THREE IN THE FIELD OF SEMICONDUCTOR FOUNDRY, THE LARGEST ENTERPRISE IN CHINA'S SEMICONDUCTOR MANUFACTURING INDUSTRY, AND CAN MANUFACTURE HIGH-PRECISION CHIPS WITH A MAXIMUM OF 14NM.

Can the photoresist used in such a world's top semiconductor factory be a general product?

Definitely not!

They need the most expensive, top-of-the-line photoresists of the 5th and 6th grades!

For others, such as display panel factories, the third or fourth grade of photoresist is sufficient.

Luo Jia went so far as to say that the photoresist they made can meet the extremely demanding fifth and sixth standards!

The shock this brought to Tang Boyun was so great that he couldn't believe his ears.

"You say it again?"

"Can we use it?"

"We have a lot of lines, which one can be used?" Tang Boyun asked excitedly.

LUO JIA SMILED AND SAID IN AN UNUSUALLY AFFIRMATIVE TONE, "FROM YOUR 120NM LINE, WHICH HAS THE LOWEST TECHNICAL LEVEL, TO THE 14NM LINE THAT HAS JUST BEEN PUT INTO PRODUCTION, EVERYTHING CAN BE USED!" ”

All of them work!?

Tang Boyun's heartbeat accelerated wildly, although the slogan of industrial substitution has been shouted for many years, but semiconductors are the king of the technology industry after all, and it is too difficult to march in this direction.

So far, almost all of the machines, consumables, and wafers used by SMIC are imported, not because they don't want to replace them, but because they really can't replace them.

China Micro is a national team, the Chinese Academy of Sciences fully supported enterprises, they have worked hard, but only won the etching machine, and in terms of technical level, it has only caught up with the world's first-class, not leading, let alone reaching the world's top.

As the largest consumable in the semiconductor industry, Xingchen Technology actually made the fifth and sixth grade photoresist, can Tang Boyun not be excited, he is almost excited.

"Do you know what that means!?" Tang Boyun said excitedly.

Luo Jia said lightly, "From silicon wafer to chip, it needs to go through thirteen processes, namely wet washing, lithography, ion implantation, light etching, wet etching, plasma treatment, heat treatment, fast heat annealing and oxidation, chemical vapor deposition, physical vapor deposition, molecular beam epitaxy, electroplating, surface treatment, packaging and testing, and polishing. ”

"Among them, in the three most important process links of lithography, etching, and injection, photoresist needs to be used repeatedly and repeatedly."

"And we have solved the small problems about consumables in the three major links for you."

Tang Boyun nodded again and again, and the eyes that looked at Luo Jia were obviously different.

This young man is an insider!

Obviously, in the world's top technology field, Luo Jia has done a lot of study and research.

"Small problem, you even said that photoresist is just a small problem." Tang Boyun shook his head, "Believe me, photoresist is by no means a small problem, but a serious problem that has plagued us for many years!" The photoresist we currently use is all imported from abroad at a high price, and once it is stuck by others, the production line built with an investment of hundreds of billions must be stopped! ”

Luo Jia smiled, "Mr. Tang, you wait first, I know that the price of imported goods is high, but I didn't say that our photoresist must be cheaper than imported ones." ”

Tang Boyun was stunned for a moment, and then laughed, "Don't be cheap!" As long as the performance is the same and the price is the same, you will definitely use your photoresist of Xingchen Technology! ”

"Let's go, let's go to the lab!"

......

Tang Boyun decided to personally preside over the photoresist performance test, and SMIC's engineers went crazy when they learned that a domestic manufacturer had made grade 5 and 6 photoresists.

They only heard that there are a few companies that can make three-stage photoresists, five-level and six-stage photoresists for display production lines, which are completely monopolized by Neon and the United States, TOK, JSR, Sumitomo, Shin-Etsu, DuPont, and SMIC have always imported the goods of these companies.

"Which factory's products?"

"I heard that it is a subsidiary of Xingchen Technology, and the factory is not far away, just in Qidong."

"Xingchen Technology? The Xingchen technology that is engaged in energy wave wireless charging? ”

"That's them."

"Reliable! Although I haven't seen the sample yet, who doesn't know Xingchen Technology, they have always been very reliable! ”

"Don't say so much, hurry up, I heard that Mr. Tang is very excited and wants to preside over the test in person."

SMIC quickly caused an uproar, and engineers began to gather at the test center, where they changed into dust suits and entered the laboratory to conduct the most demanding quality tests on Xingchen Technology's photoresists.

Luo Jia and Zhang Dongning couldn't get in, so they had to look outside through the glass.

From time to time, people brought them tea and snacks, and many people Luo Jia didn't know at all came over to talk to him, and patted him on the shoulder as a sign of approval.

The tests began in the morning and continued into the evening.

Luo Jia saw that the engineers in the experimental center wearing full sets of dustproof clothing looked very excited, constantly raising their arms and lowering them, and many people watched around the laboratory, nervously waiting for the results.

It was already completely dark, and Tang Boyun came out of the laboratory with his technicians with an excited expression, "Incredible, completely incredible, the data we measured is even better than the top performance of Shin-Etsu Chemical!" ”

Rumble~

There was a boiling around, and the staff who had been waiting for a long time hugged each other to celebrate, and seemed to be happier than Luo Jia and Zhang Dongning.

What SMIC is most afraid of is that there is news about the trade embargo, the international situation is not good, and they may be stuck by others at any time, and they have not encountered the problem of overseas manufacturers raising prices.

"Let's go get something to eat." Tang Boyun warmly invited, "I have already asked people to prepare, and after we have eaten, we will go online overnight!" ”

Luo Jia was taken aback, the actual combat on the line is not a trivial matter, which means that the samples brought by Luo Jia are directly applied to those incredibly expensive semiconductor production lines, and if you are not careful, it will be a loss of hundreds of millions.
