Chapter 288 Core
The next morning, as soon as Qiu Huoming arrived at the hall, he saw Professor Li with dark circles under his eyes walking towards him.
He held the rolled-up blueprint, leaned close to Qiu Huoming and said, "I'll give it to you after I've copied it."
Qiu Huoming nodded, "Professor Li, can you make a few more copies? It would be best if everyone in our group has one."
"Row."
Professor Li glanced at him and wanted to ask a question, but there were so many people around, including several local students, so he was reluctant to open his mouth.
"Get on the bus, get on the bus, the bus is coming..." Teacher Xuan saw Chang Gong making gestures to her outside the window, and immediately started to instruct the students.
Everyone filed out.
After everyone arrived at the factory, they began to disperse and went to wherever they wanted to go.
Qiu Huoming still followed Master Wang.
The work done this morning was no different from yesterday. After spending time together yesterday, Master Wang was obviously much kinder today.
Professor Gu said with a smile: "Not really, let me see first."
He didn't know how long it had been, but he was awakened by a "pop".
"Okay, I will ensure the quality and quantity and complete the work."
He originally wanted to find faults and calm the newcomer's temper, but this was like hitting soft cotton.
"Look, our yield rate is currently 28%. If we follow his modification, I'm afraid it can reach 40%, or even higher. We have to wait for the test results to come out..."
Qiu Huoming shook his head. "It's the first time. We don't have this thing yet."
As I waited, I leaned back in my chair and dozed off.
Professor Gu sighed, "This time, your group can already take first place based on this drawing alone."
Half an hour later, Master Wang took out another silicon wafer and put it in. "Would you like to try again?"
Qiu Huoming watched it carefully yesterday, but he only watched Master Wang's movements and he didn't know the tricks. After his explanation, Qiu Huoming understood it all at once, just like flipping through a book before an exam.
Professor Li nodded.
He began to order Qiu Huoming around and asked him to help. After a few rounds, Master Wang was surprised to find that Qiu Huoming did not miss a single time.
As soon as these words were spoken, Editor-in-Chief Zhou took a breath of cold air.
"Xiao Qiu, I'll show you how to do it today. I'll demonstrate it first, and then you can follow my instructions. If you can master this process this morning, you'll pass it. I'll teach you something else this afternoon."
Qiu Huoming became more proficient with practice, and the etching speed actually increased a little.
Professor Gu slapped his palm on the table, his hand hurt a little, he quickly withdrew his hand, muttered: "I don't believe that a freshman can design such a blueprint out of thin air..."
Master Wang pulled at his dust-proof suit, quickened his pace, and left.
Professor Li sent the drawings one by one. "This guy changed the circuit diagram of the sample. At that time, I thought he was just fooling around. I thought that since it was his first time making this thing, he should just fool around. Let him learn a lesson..."
Professor Gu smiled awkwardly and said, "I just doubted it. Since you all believe him, I believe him too..."
He put in the silicon wafer and operated the machine while carefully explaining the key steps and precautions.
He brought the drawing closer and took out a magnifying glass from his pocket.
I watched for half the night last night and only slept for more than an hour this morning. My body is not as strong as that of young people and I can’t take it.
"Okay, next, you come over and do it. Remember, it doesn't matter if you're slow... the most important thing is to be steady."
The meeting room was extremely quiet. Professor Li drank a cup of strong tea and felt a little more relaxed.
"Mr. Wang, do you need my help?"
"Ah."
He coughed and said, "I'll move the raw materials in..."
He casually glanced at the blueprint...
Qiu Huoming could finally do it himself. He took a deep breath and switched positions with Master Wang.
"No, just do what's in front of you..."
"As a result, I took it home and read it for half the night. These changes are really brilliant!"
Professor Li rubbed his temple, snorted coldly, and said to Professor Gu: "Last night, a room full of people saw him draw it with their own eyes. There were 6 witnesses! Don't slander my student."
Master Wang's hands trembled slightly. "Okay, you did a good job. Let's do the rest together..."
"Xiao Qiu, have you learned this before?"
"Is this the chip he is going to make this time?" Professor Gu raised the drawing in his hand.
In the conference room, Professor Li was holding a stack of drawings. Sitting with him were not only Professor Gu, but also Editor-in-Chief Zhou.
Master Wang became curious. He said yesterday that he would let him handle some simple operations today. He originally wanted to wait a bit, but now he wanted to let him try first.
Editor Zhou shook his head and put down the magnifying glass. "I believe him. This guy can really do it..."
"Okay, Mr. Wang, I will study hard."
Seeing that he was well-behaved, Master Wang wanted to teach him something.
He leaned back in his chair, closed his eyes and waited quietly for responses from his two old friends.
Professor Li took a short rest and felt much better.
He smiled and said, "Don't worry, with his temper, I'm afraid he won't give up until he does it well..."
Professor Li walked up to Professor Gu, took the drawing back, and then followed suit and took away the one that Chief Editor Zhou had.
"I'm going to deliver the blueprint to Huo Ming..."
"Hey, Old Li, keep a copy. This good stuff must be kept for me. I want to report it to the institute..." Editor-in-Chief Zhou stood up quickly.
Professor Gu was about to say something but stopped himself and simply stayed where he was, watching them.
"In what name?" Professor Li asked.
Editor Zhou said solemnly: "If the sample is made, it will indeed be better. The designer is him, and his name alone."
Professor Li laughed and put the drawings he had just collected back on Editor-in-Chief Zhou's desk.
"I have the originals. This is a win-win situation for both the public and the private." Professor Li yawned and took the remaining drawings in his hands. "I'll go give the drawings to Huo Ming..."
Editor Zhou got the blueprint back. He was so excited that he said, "Okay, go ahead."
After Professor Li opened the door and left, Editor-in-Chief Zhou stood up and stuffed the drawings into his briefcase.
Professor Gu asked, "Do you think this can be accomplished?"
"I think it's okay. Huo Ming is a child with a different brain. We must protect him well. As I said, for a country to prosper, it must have many talented people..."
Professor Gu stood up and said, "Let's go. Add my name to the report."
Editor Zhou smiled and said, "Let's go back to my office first."
"Oh, I heard you brought back a lot of good tea. I want to drink the Maofeng tea you brought back from Hangzhou..."
Editor-in-Chief Zhou almost burst out laughing, "Longjing! Maofeng is from Anhui Province!"
"Yes, yes, it is Longjing."
"Then I have a deal. The tea in the office is not spring tea. Spring tea is not on the market yet..."
"Don't worry, I'm not picky..." Professor Gu followed Editor-in-Chief Zhou out of the factory office area, got into a jeep together, and drove away.
In the clean workshop, Qiu Huoming was still operating the machine with full concentration, while Master Wang had already pushed in a large box of new materials.
He lifted the box down, then walked to the workbench and collected the etched silicon wafers.
Next, he will test these etched chips and package them...
In the entire semiconductor chip manufacturing process, photolithography is the most complicated process. The cost of photolithography accounts for about 1/3 of the chip manufacturing cost. It is time-consuming and therefore has extremely high requirements for operators.
Despite this, the completion rate is not high.
The testing belongs to another workshop. He assembled these semi-finished silicon wafers and pushed them to another workshop.
"Hey, Brother Wang, why are you here today!" Engineer Huang, who was testing, stopped the testing equipment in his hand and looked up at Brother Wang. They had enough manpower, with more than ten people in a row, divided into several rows, and the scene was grand.
Engineer Huang is the team leader of this group and has a good relationship with Engineer Wang.
"Xiao Huang, please help me test this batch of goods first..."
Master Wang put the box next to his workstation, "Okay, tell me."
"Okay, I'll test it right away." Huang Gong sat back down, cleaned up the table, and took out a semi-finished chip from the box...
Master Wang then turned around and walked back.
Qiu Huoming finished all the work assigned to him by Master Wang in one breath, and then he stretched his neck to look for Master Wang.
After waiting for a while, Master Wang walked in from the entrance.
"Mr. Wang, I'm done..." Qiu Huoming waved at him excitedly.
"You take a rest first, I'll do the rest."
"Mr. Wang, I'm not tired yet. You can let me do whatever you want..." Qiu Huoming felt that he was getting better and better. He just needed to practice more to improve his skills.
"Okay, this batch will also be yours..." Master Wang said, pointing to the box of materials he had just brought back.
"okay!"
Qiu Huoming walked over in a hurry.
Master Wang suddenly became idle. He looked at his familiar post and Qiu Huoming who was busy, and suddenly felt a sense of crisis.
"Hey, Xiaoqiu, which university are you from?"
Qiu Huoming was too busy to even turn his head and responded, "South China Institute of Technology..."
"South China? Is it the one in Guangdong?"
"Yes, Yangcheng, it's far away from here..."
Master Wang heaved a sigh of relief when he heard this. "You are a fast learner."
"Hey, that's because you taught me well. Only a good teacher can produce a good student..."
Master Wang raised the corner of his mouth. This young man is quite good at talking. It is pleasing to hear his words.
The two chatted for a few more sentences, and after a while, Master Wang looked at the clock hanging on the wall.
"Please finish all these first. I'll go check the test results..."
"okay."
Master Wang then walked out quickly.
In the testing workshop, Engineer Huang was still concentrating on testing. There were two boxes next to him, one indicating the test passed and the other indicating failed.
Master Wang approached and asked, "Xiao Huang, what are the test results?"
The success or failure of these chips does not depend solely on the lithography machine. Processes like oxidation, photoresist coating, exposure, and development are all key steps.
At present, other workshops cannot be transformed into clean workshops, so the dirty and messy environment and the workers' technical problems are the key factors that affect the yield rate.
"This batch you brought is well made, with a yield rate 10% higher than usual."
Master Wang could hardly believe his ears. "You said, 1% more than usual?"
Mr. Huang nodded and said, "Brother Wang, you played well today."
Master Wang patted his shoulder and said, "Thank you. I'll go back first."
"You're welcome." After watching him walk away, Engineer Huang picked up the chip again. Suddenly, he thought of a question. He turned to ask another colleague, "Hey, Xiao Chen, Engineer Wang doesn't usually come to deliver goods, does he? He's so busy, how come he has time to come out and deliver the chips in person today..."
Xiao Chen put down the instrument in his hand and said with a smile: "You don't know this, right? Many workshops have arranged internships for college students today. I heard about it from Lao Ma in the quenching workshop early in the morning..."
Engineer Huang looked at the semi-finished products in the frame that had just been inspected, and suddenly realized.
Outside the workshop, Professor Li saw that the clean room was difficult to enter, so he simply returned to the workshop office. It was warm here, and he took a nap while waiting for Qiu Huoming to come out.
When Qiu Huoming came out of the workshop, each member of their team was holding a blueprint in his hand. Jiang Yi said that Professor Li put down the blueprint and went back to catch up on his sleep.
Everyone gathered in the workshop office.
It was noon now and almost everyone in the office had gone to eat, leaving the huge office completely empty.
Qiu Huoming took back his drawings and immediately held a small meeting with the team members. The practical work would start in the afternoon, and everyone must have a clear division of labor and perform their duties...
Every step is critical.
After lunch, a group of people returned to the conference room in the office. Now they were in competition with Chen Liang and his group of local students, so the factory deliberately separated them and placed them on the first and second floors respectively.
Qiu Huoming and his team reviewed the situation again in the conference room on the first floor.
When the discussion was almost over, Qiu Huoming finally breathed a sigh of relief. "If you need help, please let us know in time. We are working as a team this time, so don't just do it alone..."
Zhao Youxin laughed, "Don't worry, we are of the same mind."
Several other people expressed their agreement.
Qiu Huoming finally calmed down. He had a few people who were willing to work hard. Regardless of success or failure, this was an attempt. If 16K could be made, then 64K could be made in the future as well...
While I was thinking about it, several other students were already yawning and taking a nap on the table.
Qiu Huoming glanced at his watch. It was still early, so he yawned, leaned back in his chair and closed his eyes to rest.
He closed his eyes, but his mind was still full of thoughts...
This internship in the largest factory in the country opened his eyes. There are skilled workers, professional researchers, designers... These are the most valuable assets. With these cornerstones, there is definitely hope of surpassing some countries.
He used to think that the level of domestic semiconductor industry was not good enough, but now it seems that the gap with foreign countries is not as big as he imagined.
However, just as he had thought before, the chip industry is an industrial chain, and both the upstream and downstream are indispensable. Like the global cooperation in later generations, once the relationship collapses, it will be a bottleneck.
During these days in the factory, he was delighted to find that China's investment in semiconductors has actually been very deep. For example, the ion implantation machine, one of the steps in chip production, has already been developed in China.
Qiu Huoming only felt that time was pressing, the domestic situation was changing, and as the funding gap widened, the future of these scientific researchers was worrying.
In the future, all these already developed projects will be stopped one by one, and the relevant personnel will be assigned to the tertiary industry...
The withdrawal of these professionals has shattered the domestic semiconductor foundation. Although it is convenient to import foreign products, the core is not your own after all...
