Chapter 83: Top photoresist

Luo Luojia drove to SMIC. On a cold day, Tang Boyun's secretary was already waiting.
After the guards went through the formalities, Luo Jia and Zhang Dongning walked off the road and came to Tang's office.
博 Tang Boyun and Luo Jia are already old friends. With a little embarrassment, Luo Jia directly went to the topic and asked Zhang Dongning to take out a sample and explain the technical indicators.
博 Tang Boyun began to relax and listened quietly, while still nodding gently.
However, after he had all heard it, he showed an extremely shocked look, and his wrists could not help shaking.
"You mean, you made a photoresist for a semiconductor factory!" Tang Boyun's eyes lighted up, and the whole man stood up, his voice asked hoarsely.
Photoresist is divided into six grades according to quality.
SMIC is second only to TSMC, Global Founder, and TSMC, and is the fourth largest semiconductor foundry in the world.
The so-called foundry means that SMIC itself does not have its own semiconductor brand, but after Huawei Hisense, Spreadtrum, these semiconductor design companies, after completing the chip design, SMIC manufactures for them.
超级 Samsung and giants such as Intel, of course, also have huge factories, but they mainly manufacture products for themselves, and they do not process for others.
Intel in particular, they have almost no foundry business. Samsung at least also manufactures Snapdragon series mobile phone processors for Qualcomm, and Intel's factory, which manufactures its own CPU, has almost occupied its production capacity.
In short, in the field of semiconductor foundry, there is a super enterprise, and that is TSMC.
AMD's CPU, Nvidia's display chip, and Huawei's Kirin processor are all operated by TSMC.
Under TSMC, Grofont was AMD's semiconductor manufacturing department in the past. Its strength is strong, coupled with TSMC and SMIC, it is called the top three.
From this we can see that SMIC is not in the role of soy sauce in the semiconductor field. They are one of the top three in the semiconductor foundry field. The largest company in China's semiconductor manufacturing industry can manufacture high-precision chips at the 14NM level.
Can a photoresist used in such a world's top semiconductor factory be a common product?
Definitely not!
They need the most expensive photoresist in the fifth and sixth grades!
其他 Others, such as display panel factories, use third or fourth grade photoresist is sufficient.
Luo Luojia said that the photoresist they manufactured can meet the demanding fifth and sixth level standards!
The shock that Tang Boyun brought was so great that he couldn't believe his ears.
"Can you say that again?"
"Can we use it?"
"We have a lot of lines, which one can be used?" Tang Boyun asked excitedly.
Luo Luojia smiled and said in an affirmative tone, "From the 120NM line with the lowest technical level to the 14NM line that has just been put into production, all can be used!"
All works! ?
博 Tang Boyun's heartbeat is speeding up madly. Although the slogan of industrial substitution has been shouting for many years, semiconductors are the king of the technology industry after all. It is too difficult to move in this direction.
So far, almost all the machines used by SMIC or consumables and wafers are imported. They are not intended to be replaced, but they are really replaced.
China Micro is a company that is fully supported by the national team and the Chinese Academy of Sciences. They tried their lives and only won the etch machine. Moreover, in terms of technical level, they only caught up with the world-class and did not lead. Not even reaching the top of the world.
As the largest consumable used in the semiconductor industry, Xingchen Technology even produced the fifth and sixth grade photoresist. Can Tang Boyun be excited? He is almost excited.
"Do you know what this means !?" Tang Boyun said excitedly.
Luo Jia said lightly, "From silicon wafers to chips, it needs to go through thirteen processes, which are wet cleaning, photolithography, ion implantation, photoetching, wet etching, plasma processing, heat treatment, rapid thermal annealing oxidation, chemical vapor phase. Deposition, physical vapor deposition, molecular beam epitaxy, electroplating, surface treatment, packaging testing, polishing. "

The photoresist needs to be used repeatedly in the three most important process steps: photolithography, etching, and implantation.

而 "And we, for you, solved the minor problems about consumables in the three major links."
博 Tang Boyun nodded repeatedly, looking at Luo Jia's eyes obviously different.
年轻人 This young man is expert!
Obviously, Luo Jia has done a lot of study and research in the world's top technology field.
"Small problem, you said that photoresist is just a small problem." Tang Boyun shook his head. "Trust me, photoresist is by no means a small problem, but a serious problem that has troubled us for many years! The photoresist we are using All of them are imported from abroad at high prices. Once someone gets stuck in the neck and invests hundreds of billions of production lines, they must stop working! "
Luo Luojia smiled, "General Manager Tang, please wait. I know the price of imported goods is high, but I didn't say that our photoresist must be cheaper than imported."
博 Tang Boyun laughed, and then laughed, "Don't be cheap! As long as the performance is the same and the price is the same, you must use your star technology photoresist!"
"Go, let's go to the lab!"
Uh ...
博 Tang Boyun decided to preside over the photoresist performance test. SMIC's engineers learned that there was a domestic manufacturer that had made Level 5 and Level 6 photoresists, and they were crazy.
They only heard that there are several companies that can produce three-level photoresist, five-level and six-level photoresist for display production lines, which are completely monopolized by Neon and the United States, TOK, JSR, Sumitomo, Shin-Etsu, DuPont, SMIC International has been importing goods from these companies.
"Which factory's products?"
听说 "I heard that it is a subsidiary of Xingchen Technology. The factory is not far away, and it is in Qidong."
"Star Technology? The star technology that engages in energy wave wireless charging?"
就是 "It's them."
"Reliable! Although I haven't seen samples yet, who doesn't know Xingchen Technology, they have always been reliable!"
"Don't say so much ~ EbookFREE.me ~ Hurry up, I heard that Mr. Tang is very excited and wants to end the test in person."
The inside of SMIC quickly caused an uproar. Engineers began to gather in the experimental center. They put on dustproof clothing and entered the laboratory to perform the most demanding quality tests on the photoresist of Xingchen Technology.
Luo Luojia and Zhang Dongning couldn't get in, so they had to look out through the glass.
Sometimes someone gave them tea and snacks, and a lot of people who Luo Jia didn't know, came over to talk to him, and patted him on the shoulder before leaving.
Testing starts in the morning and continues through the evening.
Luo Luojia saw that the engineers in the experiment center wearing a full set of dust-proof clothes seemed very excited, constantly raised their arms and lowered them. Many people watched around the laboratory and waited nervously for the results.
It was completely dark, and Tang Boyun came out of the laboratory with his technical staff, with an excited expression, "Unbelievable, totally incredible. The data we measured is even better than Shin-Etsu Chemical's top-level goods! "
Boom ~
There was boiling around, and the staff who had waited for a long time, embracing and celebrating, seemed to be happier than Luo Jia and Zhang Dongning.
SMIC's most feared is the news of the trade embargo. The international situation is not good. At any time, it may be caught by others. Overseas manufacturers sit on the ground and raise prices. They have not encountered it.
"Let's go eat something together." Tang Boyun invited kindly, "It has been prepared, after we have eaten, we will go live overnight!"
Luo Luojia was taken aback. The actual combat is not a trivial matter, which means that the samples brought by Luo Jia must be directly applied to those expensive and incredible semiconductor production lines. A little carelessness is a loss of hundreds of millions.
