Chapter 669: Brother! You have kidney deficiency!

The military's handling speed is truly fast; with Chen Guoan's approval.

A few days later, a lithography machine was delivered to the R&D workshop of Institute 11.

Looking at the huge mechanical equipment in front of them, which was silver-white all over and as big as a small room.

Zhou Yonghui and Song Qi couldn't help but swallow their saliva.

They were also seeing a lithography machine in person for the first time; in Song Qi's cognition, something like a lithography machine didn't sound like it would be very big.

But now that he really saw it, Song Qi realized how ridiculously wrong he was!

This thing is almost as big as the dormitory Song Qi lives in!

And, for how to use this thing, Song Qi and Zhou Yonghui were also confused...

"This is a mid-range lithography machine produced entirely independently by the Dragon Nation; a lithography machine, also called a mask alignment exposure machine, is known as the flower of modern optical technology!"

Zhou Yonghui, as Song Qi's "assistant," naturally shoulders the responsibility of collecting information.

He immediately took out the information he had found on Baidu overnight and read it out one by one.

"Its working principle is to use high-precision lasers to shoot at ultra-micro components such as chips, thereby achieving the intended purpose!"

"Currently, lithography machine technology is still dominated by the Dutch company NMSL! Our Dragon Nation can only manufacture mid-range lithography machines now!"

"The high-end lithography machine market is still monopolized by the NMSL company!"

"The one in front of us is a 72nm mask alignment exposure machine developed by the Dragon Nation's Long Xin Research Institute!"

"..."

Listening to Zhou Yonghui's introduction.

Song Qi nodded secretly.

Then he stretched out his right hand and gently touched the body of the lithography machine.

"Ding! Detected one Dragon Nation independently developed 72nm mid-range lithography machine! (Completeness 94%)"

"Ding! Optical instruments are all normal!"

"Ding! Laser calibration system is all normal!"

"..."

The next second, a series of system prompts echoed in Song Qi's ears.

72nm?

Song Qi shook his head.

To be honest, this precision is indeed too poor.

Song Qi vaguely remembers that on the current Blue Star, the lithography machine developed by the NMSL company should be at the 7nm level!

Compared with the other side, the Dragon Nation's 72nm is ten times worse in terms of data!

However, the real gap between the two is by no means as simple as ten times.

Whether it is from technical difficulty or the technological content contained within.

The Dragon Nation and foreign countries have at least a terrifying gap of thirty or forty years in the field of lithography machines!

Thinking of this, Song Qi couldn't help but sigh faintly.

Immediately after, the crisp system prompt sounded again.

"Ding! Modification plan is being calculated!"

"The difficulty of this calculation plan is relatively high; please wait patiently, host!"

"..."

"1. Ultra-micro optical instrument lens, being matched..."

"2. Nano-scale optical correction system, being matched..."

"3. Precision mechanical anti-wear system modification plan..."

"..."

"Estimated modification time: 49 days!"

"..."

"Modification plan is being determined; does the host confirm the modification to an ultra-high precision 3nm automatic calibration mask alignment exposure machine!"

Hearing this name, Song Qi was stunned on the spot.

3nm?

Holy shit?

This system is truly god-like!

You know, the working principle of a lithography machine is to use ultra-micro light particles to carve on chips.

However, light particles are not infinitely small!

Therefore, the theoretical precision limit that a lithography machine can reach!

Is 3nm!

Any smaller, and photons will undergo tunneling effects and dissipate directly.

That is to say, everyone in this world who claims to have built a lithography machine smaller than 3nm is, without exception, a liar!

At this moment, Song Qi was overjoyed...

"Hahahaha!"

"This system is truly awesome!"

"One move, and it directly brought out the theoretical limit of the lithography machine!"

"7nm! What's that!"

Thinking of this, Song Qi didn't hesitate and immediately pressed the confirm button!

The next second.

A fist-sized, glowing white light point instantly poured into Song Qi's mind.

The technology of lithography machines is as complex as the sea.

It is by no means comparable to ordinary creations!

In an instant, Song Qi's face turned pale, and his forehead was covered with fine sweat.

He almost fell to the ground directly!

Zhou Yonghui on the side saw this and hurriedly rushed forward, grabbing the swaying Song Qi.

"Little Song! Are you okay..."

"Last time on the aircraft carrier, you were like this too..."

Song Qi waved his hand and said: "I'm fine... just a little dizzy..."

"Dizzy?"

Zhou Yonghui's expression suddenly became grave.

"Little Song! Don't hide some things from your brother! We are all men; brother won't look down on you!"

"Brother! You have kidney deficiency! I told you to do less manual work, but you wouldn't listen!"

"Here, brother knows an old Chinese doctor; the prescription is especially effective. Not only is it good for treating kidney deficiency, but for delaying and solidifying the essence, it's even more of an expert..."

"Get lost!"

Song Qi pushed Zhou Yonghui away and roared. ===== CHAPTER 671 =====
