Shen Danqing took the lead, and the three of them rushed to the conference room. When they arrived at the large conference room, Shen Dan walked straight to the stage, and the other two people found a place to sit in the first row of the stage, which is also the consistent meeting style of Changsheng Investment Group, and everyone is used to it.

As soon as Shen Danqing sat down on the stage, he glanced at the audience, and the entire venue was suddenly quiet, and the fallen leaves could be heard. I saw that there was a black pressure in the audience, at least two or three hundred people, and chemistry research is a big subject, so there are more researchers.

"Ahem" Shen Danqing coughed twice first, cleared his throat and began to speak: "I came today and have something important to tell you." In the near future, our company will carry out the research and development of chip production equipment, and your chemical research institute will occupy a very important task.

How are chips produced? You haven't seen it, and you don't know, so I'm going to talk to you about it today.

One 20-inch diameter silicon wafer can etch nearly 2,000 microchips at a time. Because the microchip has a very delicate and large number of microcircuits, it is impossible to do it manually. Foreign scientists have invented physical and chemical methods to etch chips. The physical method is to use a lithography machine, and the chemical method is the key to the real etching of the chip. Including the later ion hybridization and copper interconnection, the whole process is chemically involved. Therefore, you are the key to the development of the whole system.

Let me first briefly explain the whole process to you. First, prepare two polished silicon wafers and coat one of them with a backing adhesive, called a negative. This primer was the first task you developed, and it required stability, strong adhesion, corrosion resistance, and resistance to UV light. Because the second silicon wafer is attached to the substrate with a substrate, which I call the substrate, it is the real material for making microchips. The second step is to coat the substrate with photoresist, and the laser is irradiated on the substrate through a mask, leaving patterns on the substrate that are not irradiated by the laser, and these patterns are the real chips. This photoresist is the second chemical glue that you are going to develop. It is extremely sensitive to ultraviolet light and deteriorates when irradiated by a laser, revealing the silicon wafer underneath when rinsed with water. Please note that this water is not ordinary water, it must be oxygen-free and impurity-free ultrapure water. Therefore, it is also your R&D task. After rinsing, it is dried and then the next stage is etching. Etching is the process of dissolving the exposed silicon wafer until the substrate glue is exposed, and then rinsing it with pure water to dry it. So far, the prototype of an independent chip has been formed. The following is an important link, the real etching circuit, the steps are similar to what I just introduced, after dozens or hundreds of repeated lithography - development - cleaning - drying - etching - cleaning - drying. Finally, the circuit was etched. The following is doping, to dope we need several impurities, such as: sulfur, phosphorus, arsenic and so on. The whole process also has to be repeated a dozen times before we actually make the various transistors we need.

At this time, each transistor is still independent and not connected, so it cannot be functional, and we need to perform a copper interconnect process on it. However, oxygen-free copper is not naturally compatible with silica, so we need to coat the surface of the transistor with an adhesive layer so that it can be attached to oxygen-free copper. Remember, it's the two ends of the transistor, and the rest of the place is to be covered with photoresist. Generally, the ion vapor deposition method is used to coat a layer of desalinated tungsten, titanium nitride, desalined tantalum, etc., which can be well stained with silica and copper, and are also conductive alloys. Since the evaporation is carried out in a nitrogen environment, the temperature is relatively low and there is little damage to the transistor. After this step, the copper interconnection process can be carried out. This process is also photolithography - development - cleaning - drying - etching - cleaning - drying and so on, to engrave ten layers of copper wire. Note that a layer of photoresist is applied to each layer of copper wire, so a unique dissolution process is required to dissolve all the photoresist to facilitate the heat dissipation of the chip. I think everyone should understand that the chemical solution for etching copper and the chemical solution for dissolving photoresist also need you to develop it.

These are chemicals that you have never heard of or seen, and the task is daunting, and I can only remind you that photoresist is an organic compound, and there will be an important substance in it, which is egg white liquid. I can't help anything else. But I can only give you half a year to research and develop, what materials and physical objects you need can be asked by the Ministry of Technology and Information to go abroad to find a way to get it back. But you also have to know that what they can get back is also the products of previous generations, which can only be used as a reference. You have to carry out further research and development on this basis, because our process technology is more advanced than foreign countries, and has reached the nanometer level, so the requirements for these chemical substances and ion vapor deposition technology are higher, otherwise the yield rate cannot be guaranteed. It may not even work out. Due to the importance of the matter, this time it is a dead order, only success and no failure. If I succeed, I will be rewarded, and if I don't succeed, I will be heavily punished. Do you understand?"

"Understood" There was a sparse echo below, and it was uneven, and it seemed that everyone was not sure.

The mentality of the employees below, Shen Danqing had already predicted. Therefore, they did not get angry, so as not to increase their psychological burden. He just said coldly "adjournment" and got up and walked out of the venue, and the secretary Liu Zeping hurriedly followed, he was used to the style of the boss Lei Li.

The two of them were gone, walking briskly. But left a lot of problems to the Institute of Chemistry.

After the boss left, all the researchers in the institute were talking loudly, shaking their heads and sighing, no one was sure.

Wang Bo also felt very tricky, but he was the director and had no choice but to provoke this. So he walked to the rostrum and slapped the microphone with his hand a few times.

Seeing that everyone in the audience noticed him, they also stopped talking. He said: "Everyone heard the task assigned by the boss just now, and it is really difficult to tell the truth." It's all chemical materials that we've never touched before, but no matter how hard it is, we have to overcome it, because the boss said it was a dead order. I'm sure you all know what matters. We all have a big reward for completion, and we are all waiting to be punished for not completing it! I have just summarized from the boss's speech, and there are only the following key points.

The first is the bottom glue. The boss said that it should be highly stable, corrosion-resistant, and resistant to ultraviolet light, and I think he said a little less, and it should be insulated. So I thought, isn't it just plastic? It's a special kind of plastic, and that's where we come from.

Second, it is photoresist. This thing is available in China, because there is already a three-inch process technology in China. Of course, we definitely want to improve, and the boss said that it contains an important substance: egg white liquid. Let's look at these two things.

Third, it is the etching solution. It is divided into two kinds, the first is a chemical solution that dissolves silica, and the second is a chemical solution that can dissolve oxygen-free copper. Let's figure out how to do it with these two features.

Fourth, ion vapor deposition. It's not our family's business, we can find a way with the physics institute.

As for ultrapure water, Wang Bo didn't say anything, because it was a necessary material for them to do chemical research, but the boss didn't know about it.

Now let me assign the task. So-and-so....... ”

After all, Wang Bo has been a leader for a long time, and he can find a way to mobilize everyone's enthusiasm, and everyone feels that it is not so difficult when he says this.

After Shen Danqing arranged all the R&D tasks, he could only wait, and at least give them half a year's R&D time, or preparation time.

Since he had to wait for such a long time, he couldn't really wait. It is better to use this time to conduct a thorough survey of its enterprises, although it is supervised by Changsheng Investment Consulting Management Co., Ltd. But they can't do everything, it's just that they have strengthened financial supervision, and they don't have jurisdiction over anything else. This is because Shen Danqing wants to give the greatest autonomy to each enterprise, so Changsheng Investment Consulting Management Co., Ltd. is not their direct superior.

The first one to find out is of course Changsheng Seiko, which has always been his heart. It was also the first real business he founded, Pioneer Material Recycling Company, and said goodbye, it was a larger scrap shop. It's just that he took advantage of the information advantage of rebirth. However, it has always earned high profits for him, and it is not half a cent worse than the profits of other companies, with hundreds of millions of net profits every year.

However, he also knew that Changsheng Seiko could not have any good news, and he had arranged too many tasks for Changsheng Seiko, and they did not have the manpower and time to develop other products. His investigation this time was just a formality, so when he listened to Wu Aiguo's report, he was in an indifferent state of mind.

"Boss, now our company's products are continuing to sell well, but the boss has stipulated the market share we want to occupy, so it has remained stable so far. ”

The subconscious meaning of Wu Aiguo's words is actually a little complaining about him, there is no company in the world that has a market share.

In fact, what Wu Aiguo hasn't said yet: Changsheng electrician.

It was a company that used to manufacture power tools, but later became independent because of the development of switch and socket products. However, the power tools were still left in Changsheng Seiko, and the name was changed to Changsheng Electromechanical. Because it involves machining technology and motor technology, it belongs to the business scope of Changsheng Seiko.

Changsheng Electromechanical's power tool products are sold abroad under the brand NB. At first, it did not attract the attention of international giants, but after a long time, of course, it was also noticed by Bosch. Although power tools are not high-tech products, they are large in quantity and have considerable profits, so Bosch attaches great importance to them. After an investigation, they found that NB's products were indeed excellent, both in terms of materials and manufacturing processes, which were one grade higher than their company's products. But the problem also arises here, you must know that power tools are commonly used products, and the price cannot be too high, even with the popularity of their company's products, it is impossible to increase it at will. If they follow the products of NB company, the same materials and the same manufacturing process, although they can do it easily, but they can't make money. It was a dilemma, so they ended up advertising to increase their visibility. However, it has no impact on the sales of NB company, after all, the power tools of the NB brand dare to smash are real, and the service life is also the longest, and the first damage lasts longer than any product, including Bosch products.

You may not know that power tools are highly fragile products, so you can see them after a short period of use. Shen Danqing has always been persistent in the pursuit of quality, and I really see the chapters here. It has also won a reputation for NB brand power tools. Another one of his requests for only 20% of the market share is also indestructible, and Bosch's advertising strategy has only affected other brands at most, but not half of the NB brand. It's a useless job.
