This year is 1950, Evan is in his sixth year in the world. He has become accustomed to life without a mobile phone, no Internet, and no computer, but the habit is just a compromise in desperation.

Evan knew that if he had done his job, he would have to wait more than 20 years to play pixel-sized video games and a weak personal computer, and more than 30 years to use Big Brother. As for the maturity of the network and smart phones, it is estimated that it would be good for him to be able to walk alone without the support of others.

As soon as he thought that he might want to use the smart machine in the old man mode, or simply didn't have this opportunity, he was extremely unwilling. So, as he got more and more capital, the more Evan wanted to do something.

For example, increase resources and investment to accelerate the development of the semiconductor industry chain.

Driven by this goal, Applied Semiconductor was born.

As Linda had guessed, Applied Semiconductor's purpose was to promote Evan's research on transistors. And the supreme masterpiece of the transistor is the computer, so the final product that Evan set for Applied Semiconductor is also a computer. For this reason, even if it is inevitable to compete with IBM.

Computers are one of the foundations of the information age, and the stakes are so great that Evan has to hold them in his hands no matter what. If successful, Evan Warren's consortium will have a backbone.

Of course, it takes a lot of time for this pillar to grow. Evan conservatively estimates that it will take at least two or three years to break even. Evan demanded a lot of it, and he hoped to launch a working transistor computer within ten years and snatch the title of the hegemon of the computer industry from IBM's "history".

Evan has set a goal that is very difficult, roughly equivalent to accelerating the development of the semiconductor industry by at least four years. To this end, Evan plans to invest most of the surplus of other industries in this plan in the coming period, except for the development funds that must be left behind. Evan judged that in ten years, it could cost hundreds of millions of dollars.

Evan did this, a little bit of a sense of obstinacy, so he didn't tell anyone about the plan so far. He knew that once others, especially the members of the board of directors who had been entrusted with important responsibilities by him this year, knew about it, they would inevitably speak out to dissuade him.

Because it's in their own interest.

When the surplus is siphoned off, its own development will inevitably be affected, and it is not surprising that the directors will react.

So, Evan was only going to do it silently.

It's better to get through the previous few years.

Of course, Evan won't go too far, after all, the major industries he is currently entering are all very promising, and if he really causes problems in development, it will be more than worth the loss.

Evan has a complete plan for the development of semiconductors, and as long as nothing happens, he is confident that he will achieve his goals without affecting the rest of the industry.

Especially after winning the board seat of Bank of America, Evan's confidence is even stronger.

"The first goal is to build a professional R&D team for transistor manufacturing technology and to complete the mass production technology of germanium-based transistors, which needs to overcome a series of difficult problems such as germanium single crystal production technology and surface treatment technology, but this is not difficult for the application of semiconductors, especially after the addition of Pufan. Well, let's go before 1952. Also, the production technology of silicon-based transistors, this is more difficult, give it five years for the time being, and then it will not work. ”

"The second goal, to find a big customer for transistors, in addition to the military, the key is to develop civilian products, which will help form an industrial chain and constitute a virtuous circle of R&D-production-consumption. The best choice for this civilian product is the radio, and then the computer, because the former is of low difficulty, and in addition, the medical device industry seems to be good, such as hearing aids or something, and this will be talked about when the time comes......

"This part needs to be trained to produce a corresponding product design team, well, with the deadline of radio production, which is scheduled to be completed by 1953. ”

"The third goal, the formation of a computer development system, this short term is not very urgent, personnel from Harvard University, although this is inevitable to compete with IBM, but there is no way, who let most of the domestic computer research schools have a relationship with IBM. ”

"The computer development team is the key, but there is a shortage of talents, this is no way, just form a combat force within two years, by the way, it is also necessary to train yourself, anyway, there is no shortage of high-level science and engineering students in California. ”

"Well, it looks like I'll have to find some time to talk to Dean Dubridge and Uncle Sproul. ”

"IBM can support Harvard University in setting up a computer lab, and so can I. ”

"These three goals are the ...... that must be achieved in the application of semiconductors"

After sending Linda away, before Pufan returned, Evan mentally repeated the plan that only existed in the bottom of his heart and never formed words: "Is there anything you didn't expect?"

"People, products, money, and the way all parties deal with each other......"

"Wait!" Evan thought as he paused, "Something seems to have slipped." ”

"Semiconductors aren't just for radios and computers. Just being used as a switch is a good thing. ”

While recalling the memories in his mind, Evan muttered softly: "In the future, semiconductors can be divided into discrete device semiconductors, optoelectronic semiconductors, logic integrated circuits, analog amplifier circuits, memory and other categories according to manufacturing technology. ”

"Discrete devices can be divided into three types according to their functions: diodes, transistors and thyristors. Among the three, the market value of thyristors is not low, and I almost ignored it. ”

As a switching element, a thyristor can operate under the conditions of high voltage and high current, which is different from ordinary transistors. Because of these characteristics, thyristors can be widely used in electronic circuits such as controllable rectification, AC voltage regulation, contactless electronic switching, inverter and frequency conversion. For the electrical industry and the power industry, it is of great significance.

"Do you want to do it?"

"Speaking of which, my neighbor, Southern California Edison Electric, is a ...... in the power industry I'm not afraid that no one will buy it. ”

"Then what are you hesitating about?"

Evan immediately took out a notebook with a black coat from the drawer, opened it, and wrote a few strokes on a blank page with a Renault ballpoint pen, attaching the date as a memo.

What he remembered was very simple, with only four capital letters.

“PNPN”

This is the four-layer structure of an ordinary thyristor.

A complete plan cannot be left on paper, and a simple "inspiration" is still possible.
