"Do I look like I'm lying?"

Zhou Tian glared at him unhappily and said.

"No, Director, the main reason is that I think with our country's current industrial level, isn't it time to develop the electronics industry?" When Song Weiguo heard that the director had misunderstood his meaning, he hurriedly explained.

"What do you mean it's not the right time? Is it the right time to wait until other countries leave us far behind? If I ask you, just go ahead and ask. Stop talking nonsense!"

Zhou Tian said, looking at Song Weiguo speechlessly. He was quite dissatisfied with Song Weiguo's suspicion, and he didn't think about it. Since he asked him to ask, there must be a way.

"OK then!"

Seeing that the director was so insistent, Song Weiguo had no choice but to agree, turned around and left Zhou Tian’s office to report to his superiors.

"This guy!"

Looking at Song Weiguo's back, Zhou Tian shook his head helplessly, then took out the blueprint and began to draw the design of the transistor.

When talking about transistors, we have to talk about vacuum tubes. Before transistors were developed, vacuum tubes were the mainstream of electronics in the world.

The vacuum tube was discovered earlier in the world.

The history of vacuum tubes dates back to the late 19th century.

In 1883, inventor Thomas Edison discovered the phenomenon of thermal electron emission while improving the light bulb, a phenomenon that was later called the Edison effect.

In 1904, physicist John Fleming used this effect to invent the world's first vacuum diode, an early form of the electron tube.

Then, in 1906, inventor Lee DeForest invented the vacuum triode tube, introduced the concept of the grid, and enabled the electron tube to amplify signals. The invention and development of the vacuum tube laid the foundation for progress in radio communications, telephones, radio, television and other fields.

To date, vacuum tubes have been in use for more than 30 years. During these 30 years, vacuum tubes have gone through the initial stage, maturity and finally the computer age, and have been updated and replaced countless times.

Today's vacuum tubes are no longer the first generation products they were.

If Zhou Tian wants to promote the development of the domestic electronics industry in the shortest possible time, he can only choose to overtake on the curve.

Among them, transistors were naturally his first choice.

What he drew was exactly an old transistor design that he had found in a document in his previous life. Of course, the so-called old-fashioned design was only relative to his previous life. In this era, it was a high-tech that foreign countries were strictly guarding against in my country.

Since my country has missed the best development stage of vacuum tubes, Zhou Tian would certainly not continue to choose vacuum tubes, but instead aim at transistors.

Compared with vacuum tubes, transistors are vastly different in both performance and application.

The six advantages of small size, fast response speed, low power consumption, low manufacturing cost, easy integration and high reliability have destined transistors to have a much wider range of applications than vacuum tubes.

Although there are many advantages, the manufacturing difficulty is also increased exponentially.

First of all, in order to successfully design a transistor, you must have extremely high material purity and micro-processing technology.

The material problem is easy to solve, as Zhou Tian has a material formula for transistors stored in his memory.

However, micro-processing technology as well as photolithography machines and etching machines are the most difficult problems.

At this time, photolithography machines and etching machines are only in the initial development stage abroad.

Therefore, if he wants to develop transistors now, it is not enough to just draw up a transistor design diagram. He also needs to simultaneously research photolithography machines and etching machines. Otherwise, the transistors cannot be mass-produced.

Fortunately, today's lithography machines are still in their infancy, and are far less complex than those of the past. They are mainly contact or proximity lithography machines, which transfer patterns by directly bringing the mask into contact or extremely close proximity with a silicon wafer coated with photoresist.

Etching machines are devices used to remove unprotected portions of material during the photolithography process.

The etching technology in 1952 was wet etching, which is a method that uses chemical solutions to dissolve and remove materials. Wet etching is relatively simple, but it is difficult to control the etching rate and selectivity.

This difficulty naturally did not pose a problem for Zhou Tian.

As Zhou Tian continued to draw the design of the transistor on the blueprint, a huge amount of knowledge suddenly appeared in his mind and then slowly merged into his memory. At this moment, he seemed to have transformed into an engineer who was proficient in transistor manufacturing.

With the help of the virtual space memory in the mind, the transistor was quickly drawn.

As for the remaining work, it is the research of photolithography machines and etching machines. Compared with transistors, the structures of photolithography machines and etching machines are much more complicated.

Until the end of the afternoon when he got off work, he was still immersed in the drawing process.

"Director, it's time for you to get off work!"

Just then, Liu Yuan's voice woke him up from drawing.

"Xiao Liu, what time is it now?"

"Director, it's already six o'clock!"

"Is it six o'clock? Time flies!"

Zhou Tian put the design drawing in his hand into the drawer and locked it. Then he stretched and couldn't help but sigh.

"Okay, I get it, you go first!"

Zhou Tian waved his hand and sent Liu Yuan away, then got up and pushed the car away.

In the blink of an eye, three days passed. On this day, Zhou Tian was still immersed in drawing when there was a knock on the door.

"Come in!"

Zhou Tian said without raising his head.

After waiting for a while, Zhou Tian didn't hear anyone talking. He couldn't help but look up and saw a strange middle-aged man looking intently at the lithography machine design he had already drawn. Song Weiguo behind him smiled with an embarrassed look on his face.

"Who are you?" Look

When he reached middle age, Zhou Tian was suddenly startled, and then he glanced at Song Weiguo who was smiling bitterly at him, and he vaguely guessed something.

"Hello, you must be Zhou Tian, ​​Master Zhou, my name is Luo Peilin!"

Hearing Zhou Tian's words, Luo Peilin reluctantly moved his gaze away from the design drawing and looked at Zhou Tian with great shock in his eyes.

"Luo Peilin? Are you Luo Peilin?"

Zhou Tian was shocked when he heard the other party's self-introduction. He was very familiar with this name. Wasn't he one of the founders of my country's electronics industry?

"Why? Master Zhou knows me?"

Luo Peilin looked at Zhou Tian's shocked expression and asked with a smile.

"Yes, of course I know. You are the top scholar in the field of electronics in our country. How could I not have heard of your name?"

Zhou Tian immediately stood up and said with a look of respect.

"Hahaha, kid, no wonder the chief specifically told me before I came here not to be fooled by your sweet talk. It seems that the chief really has foresight!"

Luo Peilin said with a smile.

"Mr. Luo is too polite. I am speaking from the bottom of my heart. Please don't be misled by the chief's words!"

Zhou Tian naturally knew who the leader Luo Peilin was talking about, and his words were no longer as reserved as they had been when facing a celebrity.

"Okay, no more jokes. When Song Weiguo told me that you wanted to study the electronics industry, I thought you were just being arrogant because you studied radar systems and anti-aircraft missiles, but I didn't expect you to be so capable!"

As Luo Peilin spoke, his handsome face showed his admiration for the younger generation. Zhou Tian's performance was beyond his expectations. He originally thought that Zhou Tian's words were somewhat exaggerated.

After all, he was very clear about the development of the electronics industry. At present, my country had almost no experience in the electronics industry. Although an electronics factory had been established, it only produced some obsolete vacuum tubes. To him, producing transistors was simply a fantasy!
