Chapter 578 "0001"
The expert team carefully checked the questionnaire and scoring documents. They felt that there were no problems before printing them out on the computer.
While fighting, some experts did not forget to praise Gao Zhendong: "General Engineer Gao, these things you made are really useful, but it is not so convenient to put them aside before."
"Haha, as long as it is convenient, it is good as long as it is convenient. I have thought of so many ways, just to make it more convenient for everyone."
After typing up the materials, the expert group returned to the venue and distributed the things to Everyone, but to everyone's surprise, Gao Zhendong also sent the scoring standards to all interested manufacturers.
"Mr. Gao, are you sending this to them too?" In their view, this is simply sending all the answers to the candidates.
"Well, let's take an open-book exam. This is completely open, fair and just." Gao Zhendong simply explained.
This set of operations made the chief engineer of the 12th Machinery Department shine.
“Well, it’s interesting. Please remember Comrade Zhendong’s process. In the future, we will use a similar method to compete in similar technologies. This is much better than everyone dancing around like crazy at the beginning today.”
As for economic competition, no one thought much about it at this time, nor did they mention it much.
Soon, the two product manufacturers completed the questionnaires and handed them back for everyone to score. The results were clear.
In the matter of LED, 1218 is leading by a cliff. Even though their silicon workshop was taken away, their remaining semiconductor production capacity still lags other factories.
Especially for their diode production, they won the Lightning Technology Award at the beginning of the year, which is very convincing.
For this result, other factories can't do anything. If they can't compare, they can't compare. Unless the leaders want to carry out industrial layout or something, otherwise only Factory 1218 is the most suitable for the hard conditions.
Seeing that the LED results came out, no one had any objections, and the leader breathed a sigh of relief. Gao Zhendong’s method was good, fair, just and open. If he lost, he would lose, and there would be no trouble.
As for when work requires it, what should I do if I want to tilt it deliberately? Then just deal with it in setting the conditions.
I have long known that in addition to technology, Gao Zhendong is also a good manager, and he truly deserves his reputation.
With satisfaction, everyone rated the recorder. Unlike LED, this time, Haihekou Record Player Factory and Cultural Audio and Video Corporation were very close.
Wen Xuankou was appointed by the Cultural Audio and Video Corporation. We invited him here this time mainly because of the tape issue.
Both are large units in their respective professional fields. They have their own strengths in the matter of tape recorders. In the end, the leaders of the 12th Machinery Department made the final decision.
The tape recorders are still produced by the Haihekou Phonograph Factory, but the matter of the tapes is left to the Cultural Audio and Video Corporation. To be honest, the 12th Machinery Department does not want to touch these things. The audio and video company has Wen Xuankou to check it by itself. Better.
After handling this matter, Gao Zhendong was also very happy. This meant that in addition to his own use, he had two more ways to make a small amount of money. It was worth spending half a day on this matter.
Before he left the 12th Machinery Department, the director of Factory 1218 specially greeted him and thanked him.
——
A few days after this matter was handled, a call came from Factory 1274. The first official full-process trial production of integrated circuit chips has reached the packaging stage. Please Gao Zhendong went to preside over the bonding of the first pin, which actually means welding the root wire.
This is the reason why Factory 1274 did not show up at the selected LED factory. Now that there are integrated circuits, they have little interest in LED, and all their energy and resources have recently been spent on this matter.
And they also know that even if they are interested, it is impossible for the superiors to continue to let them make LEDs. It is impossible to put all eggs in one basket.
Since Gao Zhendong replenished the last board of the photolithography machine in the first quarter and sent the machine and people to the 1274 factory, the integrated circuit process of the 1274 factory has been completely formed.
After a period of integration and debugging, just after entering the second quarter of 2061, they completed the entire integrated circuit process and started the first formal trial production.
After material preparation, P area photolithography, gate photolithography, contact photolithography, metal photolithography, and bonding block photolithography, different oxidation, deposition, and diffusion processes are added between each photolithography. , and there is still time for cleaning and so on. In fact, it is already a little time before trial production starts.
The bonding of leads and solder bumps, as well as subsequent packaging, are the final process of chip production and forming, and they can also be regarded as iconic processes.
Therefore, the bonding of the first pin of this first chip must be done by Chief Engineer Gao. He will not be needed later. It is estimated that his skills are not very good and he has done too much. It would be troublesome for other comrades to change.
After receiving this call, Gao Zhendong put down an IC principle circuit PCB board that had just been delivered from the electronic laboratory in his hand, and walked down. As he walked, he happily greeted the driver comrade, "hurry up" Send yourself to 1274.
Seeing Gao Zhendong's face beaming with joy and running out in a hurry, Director Yan was delighted. Seeing Mr. Gao like this, there must be some good news.
The driver, Comrade, drove the car very fast and steadily, but Gao Zhendong felt that the speed was a bit slow.
After finally being patient, the car stopped for a moment at the gate of Factory 1274. The gate guard of 1274 was very familiar with Gao Zhendong. When he saw his face, he immediately waved to let him go.
The car drove straight outside the integrated circuit process test workshop. Gao Zhendong got out of the car, not even bothering to close the door, and hurried to the building with three steps at a time.
Director Lu and Chief Engineer Lu from 1274, along with a group of comrades responsible for integrated circuit technology, as well as Fang Yinghong, Yi Zhonghai, Ma Juan, Qin Huairu and others from the No. 3 Rolling Plant who came to support, have already changed. Protective clothing is eagerly awaited.
Seeing Gao Zhendong rush in, Factory Manager Lu laughed: "Mr. Gao, you are here! You are all ready!"
Gao Zhendong shook hands with him: "I'll take it. When I got the call, I rushed over as quickly as possible. Is there no delay? ”
Director Lu smiled and said: "No, no, it's just right."
Director Lu waved his hand: "Change clothes!"
They had already changed into protective clothing and were waiting. Gao Zhendong quickly changed his clothes and entered the workshop production area. All the equipment is running. Although the first batch of the first piece is waiting for Gao Zhendong to come to pick up the first line, the subsequent products of the test batch are still being produced on the assembly line.
Everyone came to the bonding machine. It was said to be a bonding machine. In fact, it was not as tall and sophisticated as Gao Zhendong’s later generations saw on the Internet. To describe it simply, it was A soldering station with a high-power magnifying glass.
As long as it can be used, the production efficiency of the entire process cannot be compared with that in the future, and manual work is enough.
Factory Director Lu and Chief Engineer Lu extended their hands and said, "General Engineer Gao, please!"
Gao Zhendong is also not humble and will not give in when he does his duty.
He asked the comrades of the production workers next to him how to use the machine, and sat down at the work station. Everyone looked at him with excitement.
The hard work for so long is about to bear fruit.
Through a magnifying glass, the surface of the chip that has been fixed into the plastic base appears colorful and beautiful.
On the edge of the chip, there are two rows of metal-deposited crimping blocks, corresponding to the pins on both sides of the package.
Gao Zhendong carefully operated the equipment and placed an enameled wire on a crimping block. He operated the welding equipment with his other hand and pressed it onto the enameled wire.
A puff of light smoke came out, and the enameled wire was firmly fixed on the crimping block.
Gao Zhendong followed the same method and soldered the other end of the wire to the pin of the chip package.
He stood up and said with a serious smile: "Thank you for your honor! Come and check."
A worker stepped forward, looked at the magnifying glass, and announced loudly: "The inspection passed!"< br>
"Wow..."
Applause sounded like a tide. Everyone looked at Gao Zhendong, laughing and applauding.
This time, Gao Zhendong felt a little embarrassed: "Haha, what the heck, I just soldered a wire, passed, passed."
Thinking about it, this operation seems to be a serious show off.
Director Lu applauded and said: "Mr. Gao, without your long-term guidance and efforts, this wire cannot be welded, don't you think so?"
"Yes. ~~~~~~”
The comrades present laughed.
Gao Zhendong himself also laughed, it felt so good!
However, only one wire was bonded, and the rest was completed by the comrades of Factory 1274.
A skilled person is a skilled person. The comrades from Factory 1274 quickly connected the remaining ten or so wires and then started pouring epoxy resin.
It has to be fixed anyway, so it is better to pour glue directly. This is the method that the comrades of 1274 came up with. In this way, the chip itself can be reinforced.
They chose an insulating resin formula with good thermal conductivity and a thermal expansion coefficient consistent with that of the wire. After testing, the effect was very good.
Contrary to people's intuitive belief that glue filling will affect the heat dissipation of the circuit, glue filling is actually beneficial to heat dissipation. In the absence of active heat dissipation, the thermal conductivity of air is extremely poor.
It's just that this glue is a bit particular. It has good thermal conductivity and is more conducive to heat dissipation. The thermal expansion coefficient is consistent with the wire, so it will not pull off the wire during the process of thermal expansion and contraction.
After filling the glue, the worker comrades also glued the upper cover of the package on. In this way, after the glue solidifies, the chip will be considered impregnable.
On the front of the packaged chip, the first line is "SZ61000", which is a four-two input NAND gate.
The second line is 6114, which is the production date, indicating that it was produced in the 14th week of 1961.
As a bulk digital circuit chip, the entire SZ61 series does not have a production serial number, but this one is different.
The ingenious worker comrades hand-engraved the third row of numbers on the surface of the chip.
"0001".
This is the only SZ61 series digital logic IC with a production serial number among the hundreds of millions produced.
This chip has never been used, and was later displayed in the "Information Industry Museum". The introduction is very simple.
"my country's first integrated circuit chip".
