Chapter 1274 The moment of changing the world (first update, please subscribe)
While Wanhujiao was conducting intensive research to determine the basic structure of the super-heavy rocket used for landing on the moon, in the southeast corner of Chang'an, in that inconspicuous office building, a group of people were also busy.

That's it now!
Wang An looked a little nervous, and he was not the only one. In fact, at this moment, almost everyone in Wang An Computer Company was staring at the computer in front of them.

In fact, it looks almost identical to the 2000 Chinese and English text input machine, except that there is an additional tape reader on the right side.

But this is just what it looks like on the surface. In fact, its internal structure has undergone tremendous changes.

“This is the world’s first general-purpose electronic computer!”

Adjusting his glasses, Wang An's tone became a little excited, and he even emphasized:

"It can not only be used to type Chinese and English, but also to calculate data, and even to use it..."

Picking up the tape in his hand, Wang An introduced it to investor Cheng Liyun:

"Store previous data, such as previously entered text..."

In fact, the personal computer launched by Wang An was, to a large extent, a further improvement of the 2000 Chinese and English text input machine. Although its application was limited, it was the world's first word processing system with editing and retrieval functions. This "WPS" computer could display text directly on the screen and quickly modify documents using the keyboard.

Combined with the "dot matrix printer" launched by the Nanyang University laboratory a few years ago, it can print documents like ordinary typewriters and printing presses, greatly improving the work performance of office clerical white-collar workers. Not only that, it can even edit simple tables.

This invention changed the situation that office workers had been using cheap typewriters as their only equipment for nearly half a century, even though factory machinery was changing with each passing day. It was also the first computer application to create "word processing", which will still be an important function of computers in the future. However, unlike previous text input machines, it can also perform data calculations thanks to advanced integrated circuit processors.

This seemingly simple electronic computer immediately attracted attention from all walks of life as soon as it was launched. Although its price was as high as 11000 yuan, it still attracted the attention of large companies and soon became popular in the office field.

……

About half a month later, a Wang An computer appeared in Li Yian's office.

"Sir, this is the Wang An Model 100 electronic computer."

"It looks like a text input machine!"

Li Yian said with a smile that in fact, after Wang Laboratories launched the 2000 Chinese and English text input machine, his first reaction was - this guy is really a genius!
The Chinese and English text input machine solved the text input problem by using computers. He not only designed Chinese and English character libraries in the input machine, but also invented the "Pinyin input method", which allows users to see the typed words on the screen. Although the text size and font size cannot be edited, and it can only store 100 bytes, he still created a prototype of a computer.

"The difference is not big, but it can perform some calculations. The computing function is still very powerful. Some securities companies in Yongan have already purchased this kind of computer. Computer..."

Zhang Zheyuan smiled and said:

"A brain made of electronics. His word is very appropriate!"

This is a rip off!
Li Yian thought to himself that this was the term he mentioned in front of Wang An and others when he visited the Electronic Laboratory of Nanyang University that year.

Under his guidance, the experts and scholars present all chose different paths, but only Wang An chose to start his own business. This guy is really not simple!

From a text input machine to today's computer, although it seems to have some simple functions, it is still the world's first personal electronic computer.

In fact, the King's Laboratory was also researching personal computers, but they were limited by Li Yian's guidance and pursued more powerful and comprehensive functions, which in turn restricted their development.

In contrast, Wang An only upgraded the text input machine by taking advantage of the further development of integrated circuits, or chips, and it seemed like just a small upgrade, but it created the world's first personal electronic computer.

Even so, this is still worth writing about, like a miracle!
When the computer was turned on, the words that appeared on the screen were familiar Chinese characters. Li Yian smiled, and his smile became extremely bright.

Not because of anything else, but because of these Chinese characters.

Before the invention of the graphical user interface, people needed to memorize those boring machine instructions. Although DOS commands appeared later, most daily operations can be completed using these instructions that are close to natural language.

But at their core they all use a lot of English!

It is precisely because the underlying logic of computers is built on English, from programming to academic research, it is based on English. Let's not talk about whether it limits the use of other languages ​​in this field.

But one thing is certain - it is the era of electronic computers that has established English's unshakable dominant position, because the underlying logical foundation is English.

And now?

The computer in front of me is very simple, but... it is in Chinese!

And what does this mean?
In the future, Chinese will be the underlying foundation of the electronic computer industry - not only will there be independent Chinese compilers, lexical analyzers, and semantic analysis, but there will also be perfect support for underlying hardware and compatibility with software in other programming languages... not just a simple keyword translation.

Finally, the computer was turned on. Looking at the text displayed on the screen, Li Yian couldn't help but raise his eyebrows and said, "I'm not going to say it to you."

"It seems that in the future it will be the Americans' turn to learn Chinese..."

Chinese characters will become the underlying foundation of future electronic computers and even smart phones!

In the next few years, Wang An computers could be seen in all government departments in Nanyang, from the Daming Palace to the offices of all private companies. It took only three years for Wang An Computer to become the world's largest electronic computer manufacturer at the time. By the end of the 1960s, Wang An Computer reached its peak, and Wang An became the richest man in Nanyang - of course, this was on a public level, after all, no one knew how much money he had.

But one thing is certain: Wang An's legendary wealth has injected a dose of stimulant into Nanyang's electronic computer industry. After all, capital is always profit-seeking. Driven by interests, huge amounts of funds will flow into this industry, and it will also drive tens of thousands of young people to enter this industry for wealth, for dreams, and for various reasons.

This does not require the promotion of others, it is a natural development.

Sometimes, the prelude of an era is opened so suddenly that it even catches people off guard. Of course, this is just a story for later.

However, faced with an electronic computer worth 11000 South African dollars, Li Yian was still a little confused.

“It’s too expensive!”

While lamenting its high price, Li Yian specifically studied the cost of this electronic computer.

Soon, Li Yian found the root cause of why the computer was too expensive.

"101 chips are too expensive!"

The 101 chip was developed by IMD, a startup integrated circuit company. It is the world's first true microprocessor. However, due to the low yield and high cost of contact lithography machines, the price of this chip is extremely high.

This is also the fundamental reason why computers are too expensive.

"So, the key is to come up with a photolithography machine with a high enough yield rate! As long as we have a suitable photolithography machine, we can make sufficiently cheap chips!"

Lithography!
In order to bring down the price of chips, Li Yian immediately devoted himself to the research of lithography machines. Although he was a layman in lithography machines, thanks to the pain of being "choked" by Chinese people before the time travel, he knew some principles of lithography machines. After all, many articles introducing lithography machines always introduce their structure and principles.

So after briefly understanding that Nanyang's lithography technology was based on the contact-based incremental approach, I immediately began to research projection lithography machines.

Although the projection lithography machine is far inferior to the later stepper lithography machine, it is it that brought mankind into the chip era and drove the price of chips to a rock-bottom price.

Moreover, the structural principle of the projection lithography machine is not complicated. Historically, the birth of the projection lithography machine has increased the yield rate of chip production from 10% to 7% overnight, increasing by 70 times, making the price of chips extremely cheap overnight.

Naturally, Li Yian chose to study projection lithography machines. At this moment, the interface that was so familiar that it couldn't be more familiar emerged in his mind.

[You can learn the skill "Photolithography machine design", do you want to learn it? ]

Although it’s been a while, this is the system!
He would always remind Li Yian when necessary - you have the most awesome golden finger.

So without any doubt, Li Yian quickly chose to study, and then some seemingly dry and difficult to understand knowledge about lithography machines flooded into his mind.

This is not a simple skill to learn, it involves knowledge from all aspects. After completing the study, if Li Yian is willing, he can not only design a more advanced stepper lithography machine, but even the lithography machine that is said to be kissed by God - the EUV lithography machine.

Of course, its structure is extremely complex. After all, in another world, ASML spent nearly 10 years in the late s to design the EUV lithography machine. Even at that time, many technologies were still immature, especially the photoresist that could be used for extreme ultraviolet light did not exist.

As for now, the basic technology is completely blank, so we can only think about it.

"The rest will be left to time!"

After completing the skill learning, Li Yian directly drew the initial blueprint of the projection lithography machine.

"…using a reflective projection method, using two coaxial spherical mirrors, the pattern on the photomask is projected onto the silicon wafer after three reflections. This symmetrical optical path design can eliminate most of the aberrations produced by the spherical mirror, allowing the photolithography pattern to achieve the ideal resolution."

In the King's Laboratory, Li Yian pointed to the drawings and introduced the principles to the researchers. These researchers have been studying contact lithography machines in the past few years and are not unfamiliar with them. They only need to be reminded of the principles and they will immediately understand their structure.

Li Yian took out the basic drawings of a projection lithography machine. With this initial drawing, the King's Laboratory took only one week to produce the world's first projection lithography machine.

The subsequent experiments shocked everyone. Its high yield rate not only reduced the price of four-digit chips to double digits, making chips from an unattainable luxury item accessible to ordinary people, but Li Yian also proposed "Li's Law".

But no matter what, in June 1962, the world was completely changed.
