Honghuang, I am engaged in science and technology in the Wuzu

Redstone Institute of Science and Technology.

“Jingle Bell,……” The phone rang.

“Hey, hello, this is the office of the Red Stone Science and Technology Research Institute, who are you looking for?”

“I’m Bing Xue, I’m looking for Fang Hao.” The opposite side replied.

“Director, this is your phone, the ice fairy is looking for you.” The lab assistant shouted.

“Hey, Bingxue, I’m Fang Hao.” Fang Hao put down the experimental equipment in his hand, nodded, and took the phone in the assistant’s hand.

“Fang Hao, the first generation CPU has been successfully tested in the laboratory, and it can already run the system preliminarily, do you want to come and take a look.” On the phone, the Ice Banshee asked.

“Oh, really, okay, I’ll be right here.” Fang Hao couldn’t help but rejoice in his heart, it’s not easy, after a few years, this plan has finally succeeded.

“Go, Xiao Mo, let’s go and see this cross-era invention together.” Fang Hao said to his assistant with a smile.

Xiao Mo is called He Mo, a junior of He, and at the same time a genius Terran, only in his twenties.

His IQ reaches 200, his scientific talent is amazing, and he is a good seedling worth cultivating.

Fang Hao brought her to him under the love of talent, hoping to train her to become the next generation of scientific research leaders, over the years, Fang Hao felt a little powerless, too many things.

Most importantly, he wants to be lazy.

Semiconductor laboratory, Fang Hao and a large circle of researchers gathered here, in front of them is a one-meter-square circuit board, this is today’s protagonist, the second generation of semiconductor computers.

Although transistors have appeared, although transistors can replace tubes to form computers, in terms of overall performance, it has also been greatly improved than the first generation of computers, but if it is to be popularized or unlikely, it is only suitable for use in the field of scientific research, mainly because its size is still too large, and the power consumption is too large.

Not only that, this kind of computer is easy to break, a transistor computer is tens of thousands of transistors, once a transistor is broken, the entire computer will easily collapse directly.

However, it is not a problem for skilled researchers, the transistor computer is broken, it is a big deal to replace it, but if it is for personal use, it is not suitable, once broken, it can only be repaired by professionals, which is time-consuming and laborious, thankless.

After the advent of transistor computers, programming languages and operating systems also appeared, unlike Earth, the high-level language of computers uses Chinese, and only the lowest assembly uses letters.

Today’s computers are mainly used for scientific computing, and have also begun to develop vigorously in the field of data processing and process control.

Each transistor computer needs a transistor, a transistor to tune out, if three months can call out one is already very awesome, so Fang Hao has been putting hope on integrated circuits, avoiding the direct use of tens of thousands of transistors, it is too terrifying.

“These are the chips, this is the CPU?” Fang Hao pointed to the huge original and asked, the CPU chip in it was the size of a palm, and the other chips were slightly smaller.

“Yes, the chip is like this, we finally made it, and after experimental testing, it fully met the experimental requirements.” The Ice Banshee said.

“I didn’t think it was like this, it’s very good.” Fang Hao looked at this scaryly large motherboard and said against his will.

“This main control chip is only 4 bits, and there are only 16 pins. The clock frequency is 0.1MHz, about 3,000 transistors are integrated inside, we originally wanted to make 8-bit or 16-bit, 32-bit chips, but it was too difficult, four-bit chips have 3,000 transistors, densely dissatisfied with the entire drawing, 8-bit is more complex, more than ten times, that is, more than 30,000 transistors, as for 16-bit chips are more complicated, I can hardly imagine how many transistors are needed, with our current processing equipment still can not be manufactured, to be honest, this chip in 3,000 transistors or we made by hand, and then observed with a magnifying glass , Only five out of a thousand samples pass …. The Ice Banshee said.

“Hard work on you.” The corners of Fang Hao’s mouth twitched.

After her explanation, Fang Hao finally understood the horror of this chip, it was too complicated, not only the design difficulty, but also the processing difficulty.

3,000 transistors are so complex, and if one transistor is connected in the wrong place, it can collapse the entire system, which is only a theoretical design, and the manufacturing process is more cutting-edge technology.

The people around them also talked about it when they heard the introduction of the ice banshee, and discussed the research process with the people in the laboratory, and the atmosphere was very active.

Semiconductor silicon wafers are stacked layer by layer, a total of three layers of silicon wafers, and the silicon wafer structure is integrated, visible to the naked eye, God knows how to do it well, Fang Hao feels that it is very likely to be a spell.

“This chip is very useful for us, so I will bring in a few more people from other departments and work together on how to automate the production process, and our main focus will be this project.” Fang Hao looked at the exaggerated size of the chip, he could imagine the difficulty of research, and said.

“Then thank you, we want to miniaturize it next, but the machining accuracy of the machine is too poor, and we also need to call up the machine tool with an accuracy of 0.01 mm to process the chip.” The Ice Banshee said.

“If it’s mechanical, I’ll ask the river to get their machine with the highest machining accuracy.” Fang Haodao.

“Hee-hee, that’s their baby, they can’t be touched.” The Ice Banshee laughed, she couldn’t look at those misers for a long time.

“How can I help them, a few of them have turned against the sky, I will try to help you get it.” Fang Hao scolded with a smile, thinking of those guys who regarded machinery as life.

After all, it is a self-cultivated student, according to the tradition of this world, you need to respect the teacher, can you refuse to make it yourself, if it really fails, it will make their ass blossom.

Among the old people of the Redstone tribe, what they respect the most is themselves and forgiveness, and they dare not disobey in the slightest, after all, they are the ones who lead them out of trouble.

Then the experimenters in the semiconductor laboratory began to assemble the computer, successively connected to the display, keyboard, fan, power supply, etc., Fang Hao looked at this simple computer, his heart was full of excitement.

Soon, the computer started successfully, and I saw a few simple characters appear on the display.

These display software are designed by everyone, the language used is naturally Chinese, but English characters are still used for typing, after all, 26 letters for input is still very convenient, as for the underlying language and instructions are still in Chinese characters.

The lab researchers began to demonstrate mathematical calculations, demonstrating addition, subtraction, multiplication and division, and the results were very successful.

“It worked!”

“It’s really good!”

“Great!”

“Snap! Syllable! Syllable! Syllable! The scene suddenly remembered the warm applause.

“Good! That’s great! Fang Hao was also very excited, looking at this result was very gratifying, hundreds of years, he led everyone to stumble over, and finally entered the era of semiconductor computers.

“Thank you for your efforts, everyone has done a very good job, some of you may not know what our computer invention represents, what I want to say is very meaningful, representing that we can immediately popularize computers, use computers to communicate, use computers to control mechanical operation, if it develops to a high-end level, we even regret to use it to control the whole world.” Fang Hao said excitedly.

“Good!” The crowd couldn’t help but cheer.

From transistor computers to semiconductor integrated circuit computers, this is a huge leap,

On Earth, from the discovery of semiconductors at Bell Labs in December 1946 to the launch of the world’s first microprocessor 4004 in 1971, countless scientists spent a lifetime of youth and 25 years to make the first chip.

Then the personal computer was made in 1974, and in 1978, the personal computer was introduced to the Celestial Empire, that is, it took nearly forty years for humans to develop computers from scratch.

However, in this flooded world, Fang Hao led a few people to spend decades to manufacture personal computers from semiconductor raw materials, which shows that the speed of scientific and technological progress is also very terrifying.

The manufacture of personal computers means that the technological barriers today are not in semiconductors, but in semiconductor processes, that is, in the fields of machinery and chemistry.

Only when the fields of mechanics and chemistry are developed, the processes required for the integrated circuit process can be developed.

Gordon Moore, one of the founders of Intel, once said that when the price does not change, the number of components that can be accommodated on the integrated circuit will double about every 18-24 months, and the performance will also double, which reveals the speed of information technology progress.

Will the desolate earth be different from the earth in modern society, and will it also abide by this law? Fang Hao is looking forward to a magical era of science and technology explosion, instead of kicking and kicking to promote the development of science and technology like his previous self.
