Chapter 157

The situation of Zhao Lei and Jian Mingyuan is completely different. Jian Mingyuan's family relationship is very simple. Although he has parents, he is indifferent and has no relationship. A certain age, with a certain ability to be independent, can be said to be very suitable and able to warm each other.

Zhao Lei is different. His parents are still alive, there are many brothers and sisters, and the family relationship is not bad. Although Zhao Lei’s brothers are all married and have grandchildren, Zhao’s mother will inevitably use some of Zhao Lei’s things to subsidize others. people, but in general they are not partial.Their Zhao family did not lack grandchildren. Zhao Lei really didn't want to get married. Zhao's mother would definitely not agree to him adopting someone else's child. The most likely thing was to let him adopt his own brother's son.

Zhao Lei sighed deeply, and knew that he had taken it for granted.

Lu Jian didn't want to mention it either. He was still young, and Mother Lu and the others were not in a hurry, so let him live a good life for a few years.

"By the way, how do you know we're making dumplings? Your uncle said that?" Zhao Lei should have come from the door, and he probably hasn't been to the cafeteria yet.

Zhao Lei smiled, "It's really my uncle. He asked me at noon if I would go back for the New Year's Eve dinner. Then I must go back, so I asked him if he had prepared anything for the evening?"

"That's no wonder." Lu Jian nodded, as he thought.

At this moment, the cafeteria shouted, "The dumplings are ready, come and eat."

"There are also glutinous rice balls, if you like to eat that kind, you can serve that kind!"

Lu Jian stood up, patted his pants and looked at Zhao Lei who was still sitting, "Go in and eat glutinous rice balls?"

Zhao Lei hesitated, "Let's forget it! I just came here for a stroll, and I still have to go home. My glutinous rice balls should be cooked too."

Lu Jian said that he pulled it up, and said with no refusal: "What's the matter, come here, eat a few here, and just go home and continue eating."

Zhao Lei had no choice but to go in with his strength. The inside was full of excitement, laughter, applause, and conversation mixed together, full of human fireworks.

The New Year's Eve of [-] passed like this, and the factory started to go to work normally around the fifth day of the new year. Lu Jian's fourth brother and second sister's wedding were also finished. Although Lu Jian didn't go back, he let his third brother bring them Many things go back.

The busy time passed by little by little, and the time left for Lu to see them was not long.

March is the beginning of spring, and the temperature in Hu'an City in the south is almost [-] degrees or [-] degrees. The pedestrians on the road are also wearing spring clothes, and their steps are much easier.

Lu saw that their experiment had been going on for almost three months. The busy laboratory was quiet in the past, and everyone was focused on the operation of the middleman, not even daring to move. This was not the first time they had tried About 2000 transistors have been integrated, but it has been failing. This is already the 208th experiment, and it is also the closest to success.

The one who is currently operating inside is Jian Mingyuan, who is more sensitive to data and more stable in operation. This time they are using a monolithic integration process, using a complete set of planar processes such as grinding, polishing, and oxidation to manufacture transistors on silicon wafers. It is equipped with components such as resistors and capacitors.There are many and complicated processes. It is necessary to connect all the components on a very small chip to form a complete circuit as required, and to draw the circuit diagram in advance, and if you are not careful, you will make mistakes, and all your previous efforts will be wasted.

Jian Mingyuan has now reached the final step, as long as the components on the surface of the silicon wafer are etched into interconnected patterns using photolithography technology, it is considered complete, and this process is an extremely long process.Photolithography technology uses light to transfer the circuit pattern on the photoresist paste mask to the silicon wafer. This process needs to be repeated, and it takes about 10 times to completely overlap the pattern and complete all the patterns between the layers. connect.

As time passed by, Jian Mingyuan's head was already covered with sweat, but unfortunately no one dared to wipe it off, for fear of disturbing him.Lu Jian took advantage of the fact that he had completed a layer, and quickly wiped it off.

Lu Jian looked at Jian Mingyuan and found that his hands seemed to be shaking a little, so he held his hand before he did it again, shook his head and said softly: "Change, it's been too long, your hands can't bear it. "

Jian Mingyuan looked at Lu Jian seriously, "I'm okay."

Lu Jian pinched her wrist, and exerted a little force: "No, your hands are shaking, this will affect the accuracy, let Xu Yan do it."

Jian Mingyuan's hands were sore, and then he felt that his hands were sore. It's just that he was too serious before, focusing on the silicon chip, and didn't notice at all. Knowing that he couldn't do it, he didn't insist anymore, and left position, and handed over the tools in his hand to Xu Yan who was on the side.

Xu Yan took Jian Mingyuan's position just now, stared at the things on the table carefully, and was ready to do it.

Lu Jian whispered on the side: "Pay attention to where the pins are, and you must not make a mistake..."

Xu Yan moved very carefully. Although the tools in his hands were not very good, he walked down smoothly.

When they reached the last floor, everyone held their breath, waiting for Xu Yan's final operation.

Xu Yan put down the things in his hands and let out a soft breath, "It's done."

Lan Mingda walked over anxiously, staring at it carefully, but did not dare to move.

"How about it?"

"Is there no problem?"

"Is it a success?"

Everyone was excited for a while, you must know that this was the first chip that went to the end smoothly.

Lu Jian was also very excited in his heart, and quickly said: "You will know if it is successful or not, just sit down and experiment. Lan Gong, you can take them to test to see if the circuit is complete."

"Jian Gong and Xu Gong led a group of people to continue to produce a batch of chips with a value of about 2000, and others continued to do experiments to try to increase the value to 4000." Lu Jian chose Xu Yan because they were relatively young, The grasp of precision is definitely better.

"Okay." Now the project team is full of enthusiasm.

When things were arranged, Lu Jian returned to his office. He was also very nervous just now, and his back was sweating. He shook his clothes and was about to sit down and read the materials when he heard the phone ring.

Lu Jian was a little puzzled. Minister Qu just talked to him on the phone yesterday, and he didn't know who else would call here. He answered, "Hello, see Lu from the CNC machine tool laboratory, who is it?"

"Lu Gong, it's me." Director Xu's voice came from the other end of the phone.

Lu Jian was a little strange. He just went back to the electrical appliance factory two days ago. Everything went smoothly and nothing happened. "Director Xu, is something wrong with the technical department?" Probably not, listen to Xu The factory director's voice was quite normal, and he didn't seem in a hurry.

Director Xu at the other end smiled and asked deliberatively, "Mr. Lu, it's like this. The Ministry of Agriculture in the capital has sent people to inspect the agricultural machinery factory next door to us. They want to see you. Are you busy today? Are you there?" Time to come over?"

When Lu Jian heard this, he knew that he still had the right to refuse, so he was not polite, and said directly: "Director Xu, I really don't have time today, the experiment has just made some progress, I have to keep an eye on it, and we There is also a project progress meeting at noon, so I really can’t leave.” Lu Jian did not lie, they will have a project progress meeting every month, usually after lunch, mainly to better cooperate with the teams. Progress, like Lu Jian, their CNC device project team will cooperate with the server device team.

"That's it! That's fine, I'll push it for you." Director Xu readily agreed, but Lu Jian was still a little puzzled, feeling that something was wrong with him. Shouldn't he be persuaded to go over? I went by myself.

"Then trouble Director Xu." Lu Jian didn't delve into it, anyway, he didn't want to deal with those people, he still had a lot of things in his hands, now that the chip is out, the follow-up work can start.

"It's okay, it's okay, XCMG and Jiangong should be busy too, right?"

Lu Jian raised his eyebrows, "They are also very busy. The experiment has reached a critical point. Do those people from the Ministry of Agriculture also want to see XCMG?"

Director Xu over there laughed, "Hey, this was also guessed."

Lu Jian was silent, this is really true, he just guessed randomly, but he didn't expect to be right.

"Okay, I'll take care of it here, you can do the experiment with peace of mind, just come back earlier."

"Okay." Lu Jian knew that something must have happened, but Director Xu didn't mention it, so he didn't ask further.

The phone was hung up with a "click", and Director Xu on the other side put the phone back in place.His face was a bit ugly, he was sitting in his office at this time, and opposite him was his deputy, Factory Director Zhang, who had an ugly face.

When Director Xu hung up the phone, he asked worriedly, "Old Xu, can you not see them coming back?"

Director Xu snorted nonchalantly: "They want to poach our people, and I have to send them up with my own hands. Anyway, Lu sees that the project they are working on is very big and the time is tight. It is normal that they can't spare time. Could it be that they You can still go to the laboratory of the machinery factory to confirm it."

Director Zhang thought more about it: "But you can't give them any face, right? At least let Lugong and Xugong come back for a while? After all, the other party said that we should solemnly thank the inventors of these agricultural machinery. None of them will come? Besides, Lu Gong and the others still have projects in hand, so they can only think about it."

Director Xu still had a straight face, showing no sign of persuasion: "If you can't do it, you can't do it. I'm not used to their problems, and they always ask for help, and they always call me pitiful. This agricultural machinery factory can't always count on us, can it? "

Factory Manager Zhang was helpless, knowing that he couldn’t persuade him, so he could only say: “Then let Ye Gong go and meet him, anyway, he is also the deputy head of our technical department?”

Director Xu nodded: "Alright, but they don't want to take it away alone."
