Chapter 138: You are not afraid of shadows

God said, there should be light, and so there will be light.

——The Old Testament Genesis of the Bible

God may be omnipotent. He created all things, birds and animals in the world. What's even more amazing is that he created an animal like humans. Perhaps because humans were originally created by God based on their own image, they possess certain skills - thoughts and creativity.

Five thousand years ago, humans lived a life of eating raw meat and drinking blood, but they often became the late-night snack for wild animals.

Before gunpowder was used and military, the pace of human civilization still maintained its usual speed and refused any leaps and bounds.

When the horn of the industrial revolution sounded, the world changed drastically. Trains and cars replaced carriages, factories and production lines replaced handicraft home workshops. Science and technology are increasingly showing its power. It only changes people's lifestyles and working methods, changes the world's appearance, and the speed is getting faster and faster.

Since the emergence of the first integrated circuit in 1958, the arrival of a new technological revolution has been acknowledged. With the increasing degree of integration, large-scale integrated circuits and ultra-large integrated circuits have emerged one after another. In 1968, humans could integrate more than 1,000 transistors on silicon wafers of the same size. By 1978, 156,000 transistors could be integrated on silicon wafers of the same size.

In October 1985, Intel released the revolutionary 80386dx processor, and CPU also entered the 32-bit era from 16-bit. In response, Li Siming could only sigh across the ocean and stare at him and anxiously.

New Year's Day in 1986 is coming, but MSI Technology only has two additional signs in the lobby on the first floor of MSI Building in Shenzhen. MSI Technology Company established two research centers or laboratories at the end of November of that year: the wafer manufacturing technology research center and the integrated circuit application design center. But it was just listed.

The former Li Siming personally served as the director, while the latter was led by Su Chenggong to conduct research on integrated circuits. At the same time, Li Siming also served as the company's chief engineer, but so far, he has not had many opportunities to show his outstanding qualities in the semiconductor field.

Li Siming's father-in-law couldn't help but make seven calls in a row within two months to inquire about progress. He seemed to be more anxious than Li Siming. However, people often say that Rome was not built in one day.

If so, Li Siming was willing to assure the God of the West, Allah of the Middle East and Buddha of the East that MSI semiconductor had invented a popular technology, and even the old lady in the alley could easily make semiconductors with a diffusion furnace. Or he could also assure the Food and Agriculture Organization of the United Nations that MSI had successfully transformed, entered the field of agricultural technology, and cultivated a kind of rice seed that it did not require fertilizers or careful care, but could also reach the level of yield of tens of thousands of pounds per mu. Running into the era of communism, Li Siming hoped to reappear again.

In fact, it doesn't work. Therefore, Li Siming could only honestly devote himself to the construction of the wafer factory. Technology is not allowed to exaggerate. He knew that there were still a lot of problems waiting for him. At the same time, Su Chenggong led his IC team to design and research on the existing small art line for experiments, hoping to use the self-produced IC as soon as possible.

Silicon, one of the most numerous elements on the earth, is at the junction of the metal element region and the non-metal element region in the periodic table, so it has the properties of a semiconductor. It is suitable for the manufacture of various tiny transistors and is one of the most suitable materials for the manufacture of modern large-scale integrated circuits. The surface of the crust is useful in the surface of the earth. Silica dioxide ore is refined by an arc furnace, chlorinated hydrochloric acid, and distilled to make high-purity polycrystalline silicon, with a purity of up to 0.999999999999999999999999. The wafer manufacturer then melts the polycrystalline silicon and then adds a small particle of silicon crystal into the melt.

The body seeds are then slowly pulled out to form a cylindrical single crystal silicon crystal rod. Since the silicon crystal rod is gradually generated by a small grain in the molten silicon raw material, this process is called "growth". After the silicon crystal rod is then ground, polished, and sliced, it becomes the basic raw material of the integrated circuit factory - silicon wafer. This is the "wafer". The "grain" of the entire semiconductor industry is called the previous process in the semiconductor industry. Whether it is CPU, future mobile phones, DVD chips, or some consumer electronics, such as color TVs, and audio are all made on this basis.

This technology was also available in China. Before the 1970s, the gap between it and abroad was not very big. When the National People's Congress organized the semiconductor industry, the news that the old lady made semiconductors, the "big satellite" was boasted in newspapers that era.

But in high-tech, it is like a sprint race. Two people start at the starting point at the same time. If you want to stop and take a breath in the middle of the way, in the blink of an eye, others have reached the finish line. The larger the diameter of the wafer, the higher the technical level, and the domestic technology is still stopped at 3-inch technology. This is the case with the state-owned factory where Li Siming once worked. Foreign countries are already using 5-inch technology to develop 6-inch technology. Because the larger the wafer, the more chips can be used to make integrated circuits and the lower the cost. Bosses like it.

An integrated circuit is a complete set of planar process technologies such as grinding, polishing, oxidation, diffusion, lithography, epitaxial growth, and evaporation on a small piece of silicon wafer to simultaneously manufacture transistors, diodes, resistors and capacitors on a small piece of silicon wafer, and a certain isolation technology is used to isolate each other in electrical properties. Then, the aluminum layer is evaporated on the surface of the silicon wafer and etched into an interconnection pattern using photolithography technology, so that the components are interconnected into a complete circuit as needed, and a semiconductor monolithic integrated circuit is made.

The principle is very clear, silicon is everywhere, and inconspicuous sand can produce raw materials for expensive CPUs, which reflects the value of knowledge. However, the process technology is an extremely complex process. For example, when the manufacturing process is the same, the more transistors the processor core size, the larger the processor core size, the smaller the number of chips a silicon wafer can produce, and the cost of each CPU will increase accordingly. On the contrary, if a more advanced manufacturing process is the opposite of the wafer size, the smaller the size that can be etched,

The more chips a wafer can produce, the cost will decrease accordingly. For example, in 1978, the etching size of Intel 8086 was 3μm, and in 1985 it was 1.3μm. Every two or three years, the technology will increase by one level, and the corresponding investment will increase by one level. Moreover, with the complexity of the technology and the increase in the costs of labor, land, equipment, and raw materials, this investment will also increase geometrically, and the risks will be extremely great, especially when you do not have core technology.

There are all equipments that can be said to be the top ones. After several years of preparation and planning, Li Siming has a large number of high-tech equipment. However, the establishment of a wafer factory is not a simple matter. It involves water treatment systems, air conditioning systems, and dust-free systems. Li Siming worked in a military system wafer factory for a while in his previous life. It was an 8-inch factory, so overall technically speaking, there was no problem in establishing a 5-inch factory, but the details still gave him a headache. Because this involves multi-disciplinary professional knowledge such as metallurgy, chemical engineering, machinery, electronics, and automatic control.

Li Siming devoted himself to work with great enthusiasm, but he still tried his best to make full use of the daytime and try to go back early at night because he has his family.

Career and family are a contradictory thing. In countless celebrity interviews, reporters will mention how celebrities deal with the relationship between the two, but the answers given are often unreferenced. Those celebrities will say, I am grateful to everyone in the family members for how they support my career, and how I take time to spend time with my family. Everyone will say this, the key is how to grasp the right position.

Li Siming is also learning how to master the measure. His son, Comrade Li Xiaoming, has fun every day, and is extremely energetic, and he sleeps loudly at night. Anyway, when Li Siming returns home every day, he always lie in the cradle to sleep. He may be the happiest person in the world, carefree. It is not enough to describe his happy state, because he is too young to use these two things.

Yang Yue, who became a mother, had a maternal brilliance on her face and a slight smile on her lips. Everything in this world is beautiful in her eyes. Li Siming was a little jealous. Why should women be born to care about life and family, while men must have a successful career, strive to start a business, and be strong and unyielding. Therefore, if women accidentally produce a few "powerful" points, they are called "strong women", while men become strong men are often considered natural, and if they fail to achieve anything, they are called "slacky women".

"The way of heaven is unfair, why am I a man?" Li Siming thought so, "Maybe I won't have so many ambitions if I become a woman!"

Therefore, it makes sense for Hollywood actresses to think that Li Siming has signs of sexism.

"What are you thinking?" Yang Yue snuggled beside him, his half-naked beautiful body made him unable to help but touch his feet.

"I didn't think of anything!" Li Siming said.

Yang Yue interrupted his dishonest hand and said softly: "I'll discuss something with you!"

"Discussion? You have a lot of sir. Just give me a command. I promise to do it!" Li Siming said with a smile, "I'm so embarrassed to use the word "Discussion."

"Tell you serious things, you are very busy during the day, aren't you?"

"Yeah!" When it comes to work, Li Siming felt a little tired and couldn't help but yawn. This might be a conditioned reflex.

"Xiao Mingbai is making a fuss all day and is in good spirits. He goes to bed early at night."

"Isn't this very good? If it's the other way around, it's troublesome. If you hold a concert every night, you'll be lawless!" Li Siming said, "I'm worthy of my son. He has been so conscious and disciplined since he was a child. He is a soldier!"

"But sometimes our son can't see you once a day, don't you think this is not normal?"

"Distance produces beauty. If you meet every day, it will damage my authority." Li Siming said with a smile, "It just gives you the opportunity to show off. Don't people say it? "A good wife" is to praise a great mother like you."

"Don't just pick up all the nice words, but I've heard someone say a word, 'Model husband'!" Yang Yue disagreed with Li Siming's statement, "Are you so humble?"

"We don't fight with others. As long as I am the best in your heart, I will be satisfied." Li Siming said with a smile, with a very pleasing expression.

"Look at what you said, of course you are the best in my heart." Yang Yue pinched him and leaned into his ear, "How could he marry you? Just be content. However, I have never seen your Hong Kong secretary. I heard that he is very beautiful and professional. What's the point of hiding in the company all day? Which day will you bring your family to let me see?"

Li Siming sat up "live" and said for a long time: "Xiaoyue, you won't be like other women, right?"

"What's wrong with other women?" Yang Yue stared at him. She felt that as a member of women, it was necessary to correct the image of women in men's minds and maintain world peace.

"I'm not afraid of the shadow slanting. I've said before that you women like to think about it, and what nothing is nothing." Li Siming stroked his face and smiled bitterly.

"What are you so anxious to confess? I didn't think much, it was you who thought too much. There is no silver here." Yang Yue burst into laughter when she saw Li Siming's helpless look.

"After a long time, is it still I wrong? Okay, I'm wrong. We are a man, so we must have the temperament of a man." Li Siming said, and he pinched her delicate nose intimately. "In the future, you are not allowed to think randomly. He is still a beautiful girl, pay attention to the influence!"

"You are quite sympathetic!" Yang Yuejiao smiled.

"Well? I was wrong again. When it comes to such a thing, I am just a mute. Just like Saburo Watanabe for forty years, I can tolerate it and not express any opinions." Li Siming surrendered immediately.

"If you don't speak, that means you're accusation!" Yang Yue took advantage of the victory and pursued him.

Li Siming felt that he could not give in anymore. The eloquence that he had always been proud of was not very useful today. Yang Yue was so familiar with him that he had both received the true teachings. As the saying goes, those who are close to the red are red, and those who are close to the ink are black.

He turned over and pressed Yang Yue under him, preparing to "work on family law". Just as he was carrying a gun and jumping into the horse, his son protested. His son, who was lying in the cradle, woke up at this time and cried loudly. He probably either pee or hungry.

Yang Yue quickly pushed Li Siming away, half-naked, picked up his son, lay in his mother's warm arms, and listened to the songs his mother sang softly, the son stopped crying and fell asleep in a daze again. Li Siming stared at his son, extremely envious.

"I seem to have heard the lullaby you sang, and it smells of the northeast wind?" Li Siming asked, "You didn't learn it specifically when you were a little girl in the Northeast, right?"

"What little girl? She's older than you!" Yang Yue said shyly, "I'm happy!"

"Hey, I really want to go back to the Northeast to take a look." Li Siming said, with a hint of sadness on his face. "Our old company commander and instructor have asked someone to bring a message several times and asked me to go back and take a look. He also asked me if I look down on them? Why do I look down on them? What qualifications do I have to look down on them?"

"It's hard for you to take time out now, but you're getting busier and busier as you live." Yang Yue comforted, "When you have time, I'll go with you. Our family of three will go!"

"Okay, but I have a condition!" Li Siming said, "In the future... I won't be allowed to think about it all."

"That depends on your performance!" Yang Yue felt it was necessary to stay alert.

"Well..." Li Siming agreed in a daze and fell asleep.
