Chapter 287: Change of Thinking
Chen Liang turned his head to look at Professor Gu, and immediately said with a smile: "I'm afraid it's too late to change the circuit diagram. Don't worry, this circuit diagram is almost the same as the one I made last time. It took a little longer then, but I guarantee that I can make it in five days this time."
Professor Gu waved his hand and said disdainfully: "Alright, go to the cafeteria to eat. Remember to come to the conference room after dinner to arrange the afternoon procedures."
"Okay." Chen Liang called his companions and everyone filed out.
Qiu Huoming and others took the box containing the chips and put it in their schoolbags, then followed Zhao Youxin and the others out the door. On the way, Qiu Huoming directly told them what he was going to do.
Jiang Yi hesitated, but Zhao Youxin said, "They were just in the workshop, and everyone saw it. They are very familiar with the process..."
"We don't have such a large factory there, and this is the first time we have seen these equipments. If we make the same thing as them within five days, we will not have any advantage."
Qiao Yuxiang and Wu Dali nodded, both expressing their agreement.
Jiang Yi thought about it and realized that this was indeed the case. He looked up at Qiu Huoming and said, "Brother Huoming, can you guarantee that you can draw the blueprint of this chip?"
Qiu Huoming smiled and said, "I'll stay up late today to draw it."
Zhao Youxin had spent more time with him and trusted him more than others. Hearing this, he was overjoyed. "Let me be frank. If we succeed, it's the result of all our efforts. If we fail, we have to work together. We can't put the blame on Huo Ming..."
This machine is one of the equipment imported from abroad at a high cost, and everyone treasures it very much.
Qiu Huoming said nonchalantly.
"It's time to get off work. Let's go. I'll try to learn a little bit tomorrow..."
Qiu Huoming reached out and patted his shoulder. "This is the first time we've seen this thing. We are novices and they are experienced. We can't say they are cheating. We can only say it's a coincidence..."
Chang Gong pushed the door open and walked in. He looked around and said with a smile, "Oh, everyone is here. Let's discuss which part each of us will be responsible for studying?"
Professor Gu waved his hand down and said, "I didn't choose this blueprint... If you have any questions about this, you can ask."
Chen Liang pushed his chair away with a bang. He glared at Jiang Yi, "You're from the countryside. You've never worked on high-tech stuff. Who are you blaming... who the hell is cheating? I spent three months painstakingly working on this by following the blueprints!"
Qiu Huoming and several other students started to grumble. After a while, he smiled and responded, "Don't change it. It's a waste of time. Let's just leave it like this."
"Also, I have another question. If the sample chip is damaged, will it matter?"
He looked at Qiu Huoming and Zhao Youxin proudly, "This is what we are going to make this time. To tell you the truth, I polished it myself at the end of last year..."
Qiu Huoming also closed his eyes and rested for a while.
Jiang Yi's face immediately darkened. He turned his head to look at Professor Li and muttered, "That's equivalent to cheating..."
Everyone then followed Chang Gong out of the meeting room.
Time passed unknowingly and it was finally time to get off work. Master Wang was quite satisfied with Qiu Huoming. This student was not like some people who would touch people randomly as soon as they came up. He was smart and polite, which pleased him.
After lunch, everyone headed back.
This sample is crude and the painting process is very poor, but it is indeed a finished product.
Qiu Huoming remembered most of Master Wang's actions, and then he looked at the silicon wafers. These were to be etched...
This equipment is expensive, and Master Wang always operates it independently. He did not agree to let Qiu Huoming operate it, so Qiu Huoming just watched from the side.
Everyone was delighted, even Jiang Yi, who seemed a little nervous, smiled.
Everyone used their brains in the morning and got up early, so they just lay down on the table and took a nap.
Only Chen Liang had a gloomy face. He stared at Qiu Huoming and said, "I can only be responsible for my part of the process. I won't be involved in other things."
As soon as these words were spoken, the conference room suddenly became lively. Everyone started talking at once and soon came to an agreement.
The photolithography machine is one of the indispensable equipment in the chip manufacturing process. It is used to etch the chip surface and engrave the circuit pattern in the chip layer by layer.
Professor Li looked at Qiu Huoming and asked, "What do you think?"
When I entered the conference room, it was empty. The five local students and several teachers were not there.
This man is quite proud.
"Of course, anyone who wants to watch it can."
About twenty minutes later, Professor Li and his colleagues came in, followed by the group of local students.
He was using the equipment at school and could only do it in his spare time, so it took a long time.
Qiu Huoming smiled and said, "It's up to you. This time we are working as a team. As long as your teammates don't object..."
Qiu Huoming went to the clean room. After entering the door, Qiu Huoming was put on a dust-free suit and followed his master into another door.
His master was named Wang, a serious young man. After he entered the company, he went to work on his own. Qiu Huoming followed him closely and learned to do whatever he did.
Professor Gu knew what he was going to do and nodded immediately, saying, "It was just a sample. If it's broken, it's broken..."
As soon as these words were spoken, several students around Chen Liang showed joy on their faces.
There was another implication in his words, but he didn't say it out loud. The chips at that time had many defects. For example, the chip used for Qiu Huoming could only be used as a sample and the quality was not up to standard.
When Chen Liang sat down, he took out a chip from his cotton coat pocket.
Qiu Huoming used to use crude methods for etching in the laboratory, and this was the first time he had seen such advanced equipment.
Qiao Yuxiang laughed, "I understand this point. Huo Ming, can I watch you draw?"
Wu Dali immediately expressed his opinion, "I agree. We can't just enjoy the good times without suffering."
Current photolithography machines can already use ultraviolet light generated by high-pressure mercury lamps for etching, which places extremely high demands on lenses.
Jiang Yi didn't dare to say anything when he heard this. He was indignant and could only lower his head to hide his anger.
Master Wang spoke.
Qiu Huoming was delighted, "Okay, thank you, Mr. Wang."
When I went out and took off my dust jacket, the sun had already set outside.
Qiu Huoming did not rush to eat, but found Chang Gong and asked for a batch of tools and materials. After getting the materials, he hurried to the cafeteria.
After everyone had their meal in the cafeteria, they were taken back to the guesthouse by bus.
Everyone in the car was yawning. The intensity of the work was greater than expected. Even Chen Liang and his group spoke less.
Professor Li did not sit with Professor Gu, but squeezed together with Qiu Huoming and others.
"How do you feel about your first time at work?" he asked with a smile.
Jiang Yi rubbed his hands and said, "It's OK, but a little boring."
Zhao Youxin and the others gave similar responses. They were excited at first, but after doing the same thing so many times, they became a little bored.
When asked about Qiu Huoming, he thought for a moment and said, "There are many things to learn. To make a chip well, it is not just a simple design, but it depends on the entire ecological chain..."
He looked at Zhao Youxin and the others and said, "Each of us is a link in the ecological chain. If there is a mistake in any step in the middle, it may produce defective products."
Zhao Youxin straightened his back and said, "Okay, I will observe carefully tomorrow. I will not leave the front line even if I am only slightly injured. I will never complain or feel tired."
Qiao Yuxiang asked, "Huo Ming, if you want to draw a blueprint tonight, why don't you go to the lobby? There is a table there. There are not many guests at night, and the lights there are brighter. The lights in the room are too dim."
Professor Li asked, "Are you going to change the plan? You have to know that you only have the physical objects in your hands. Converting the physical objects into blueprints is only the first hurdle. Then..."
After listening to him, Qiu Huoming responded, "Professor Li has a point, but no matter how things change, they still remain essentially the same. I want to give it a try. If it doesn't work, we can just use the drawings in the data without delaying things."
After saying this, he rubbed his brows, moved his fingers, then looked at Qiao Yuxiang and said:
"Your idea is great, let's meet in the lobby."
He looked at the others and said, "You can come and watch if you like."
Jiang Yi responded immediately: "I'm here."
Zhao Youxin laughed and said, "I'll pour you some tea and water."
Wu Dali looked at Qiu Huoming dully, and after a while he managed to say: "I'll stay up late with you..."
Qiu Huoming laughed, "We are a team, and our classmates are united, and we can break iron with our strength..."
Everyone laughed together.
Professor Li stopped talking. He leaned back in his chair leisurely, looking at the night view on both sides of the street. Winning or losing is not important. This time he came mainly to see the world. Regardless of success or failure, the spirit of unity of these kids is worthy of praise.
Teacher Xuan was mainly responsible for daily life. Seeing that the others had finished their discussion, she said, "If you need anything, you can come to me, Huo Ming. I have some paper, rulers, and scale plates. I'll ask Dali to come over and bring the things down to you later..."
Wu Dali replied: "Okay, I'll go upstairs with you to get it."
The car stopped at the door of the guesthouse. Chang Gong saw that they had all gone in, and he was worried, so he chased them into the lobby and reminded them, "Same time tomorrow, get in the car directly..."
Everyone responded, and he returned to the car with peace of mind.
Qiu Huoming was making preparations in the lobby, and soon Professor Li and Teacher Xuan came down.
The group of people were quite curious and surrounded Qiu Huoming.
Qiu Huoming exhaled and opened the box...
There was actually another reason why he was so sure. He had looked up old information from the United States before, and the drawings of this chip were not complicated, so he could easily replicate it.
These memories became clearer as he learned more about semiconductors. He didn't know the principles before and felt bored when he read them. But now, it's like looking at a microscopic world. Each component represents a different use and has different characteristics. How to sort them out and perfect this microscopic world...
It's a wonderful process.
"The smell is a bit strong, please spread out a little, and it's best to cover your mouth and nose..." Qiu Huoming reminded them, and when he saw them make way, he put on gloves and a mask, and planned to open the chip package.
He used the heating method to open the lid.
The heating plate was obtained from Chang Gong. The chip was placed on the heating plate. He carefully sucked a small amount of fuming nitric acid with a pipette and dripped it on the surface of the chip. Then he poured acetone into the beaker next to it...
His technique was so skillful, as if he had done it countless times.
Professor Li looked at him steadily. His practical ability was truly amazing. His movements were as smooth as flowing water, which made even an old researcher like him feel pleasing to the eye.
Just as artists enjoy watching performances, researchers enjoy this kind of practical experience.
Gaining step by step, this feeling can only be understood by those who are addicted to it.
Qiu Huoming's hands were very fast, and after a few moves, the surface of the chip was exposed.
Qiao Yuxiang watched intently, and only breathed a sigh of relief when she saw that the surface of the chip was visible to the naked eye.
Next comes drawing.
This chip was independently developed in China, and the ideas used are very different from the blueprint he had seen before, but the results are the same.
As Qiu Huoming was drawing, he finally found something unreasonable in the drawing. He stopped writing and stared blankly.
The people around him thought he couldn't draw anymore, Jiang Yi sighed, "Forget it, let's just use the drawings in the materials."
He yawned. It was almost 12 o'clock and he was very sleepy. However, other people were still here, so he couldn't just leave.
Qiu Huoming didn't hear Jiang Yi's voice at all. He was already immersed in the world of chips. After thinking for a moment, he decided to change the drawings and no longer follow the samples.
He picked up the pen again and began to paint.
Professor Li, who looked a little tired, suddenly opened his eyes wide. He leaned closer to Qiu Huoming and looked at his unfinished drawings.
The predecessor of this chip was 4K, and he was one of the developers, so he is more familiar with the design concept of this blueprint than most people.
"Why do you want to change it like this?" He wanted to ask, but was afraid to interrupt Qiu Huoming's train of thought.
For a moment, I felt like my heart was being scratched by a cat.
Qiu Huoming was completely unaware that Professor Li beside him was already getting restless. He remained calm and continued drawing.
When the clock stopped at half past one, the drawing was finished...
Qiu Huoming breathed a sigh of relief, only to find that his eyes were sore. He closed his eyes and relaxed for a long time before muttering, "I have to take a break after painting for an hour in the future..."
When he opened his eyes again, he found that the drawings were gone. The drawings were in Professor Li's hands, and he was leaning close to the light to examine them carefully.
Qiu Huoming stretched himself and said, "Professor Li, I'll leave the blueprint here with you. I'm going back to sleep first."
The other students had already been unable to hold on any longer, and upon hearing what he said, they all happily wanted to follow him back.
Professor Li glanced at Qiu Huoming and saw that he was indeed very tired. Although he had many questions in his mind, he still couldn't bear to part with this student. His voice was a little hoarse, "Okay, you guys go back to sleep first."
Qiu Huoming returned to the room, took off his coat in no time, and lay down on the bed. He fell asleep almost as soon as he pulled the quilt over him.
The other people in the room were not much better. They were all young men, and as soon as they touched the pillow, they became nervous.
