A nation's industrial development begins with junior engineers.

Chapter 753 The First Chapter of Real Money!

Jiang Xia looked at the heavy bag of documents, then at Engineer Chen's slightly hunched, thin figure disappearing at the top of the stairs. A strange tightness gripped her heart, and an inexplicable worry lingered.

His instinct was to chase after him and ask what was going on, even if it was just to say "take care of yourself" one more time.

But just then, Old Wang's hurried voice came from the office at the other end of the corridor, interrupting his thoughts:

"Bro, the Academy of Sciences' encrypted channel has gotten in first! They specifically want to talk to you! I was just about to call back to headquarters when they intercepted it!"

Oh, is this Dr. Lan Ying?

I've been so busy since I got here that I've completely forgotten about the "chip" thing.

Jiang Xia's panic instantly vanished, and she staggered towards the communications room, not even noticing the file bag bumping into the door frame.

A chip! This is a chip... If it succeeds...

Jiang Xia rushed into a small office that Lao Wang had converted into a communications room, and took the headset and microphone. Dr. Lan Ying's clear, slightly excited voice immediately came through, transmitted via the upgraded miniaturized digital secure radio:

"Xiao Jiang! Did you hear that? Did you hear that?"

"Success! The first integrated circuit fabricated using the PMOS method has been successfully manufactured! Excellent repeatability!"

Dr. Lan Ying's voice was filled with barely suppressed excitement, "I knew you'd be thinking about this, so I made sure to let you know first!"

"Really!"

"Of course it's true! And guess what the feature size is this time?" Dr. Lan Ying's tone was unusually cryptic and proud.

"The design requirement is 15 micrometers... Seeing how happy you are, could it be... could it be that our research team really made it to 10 micrometers?" Jiang Xia's voice trembled involuntarily, almost unable to believe it.

No way, no way! The whole set of equipment is handmade, and the photomasks are hand-drawn. Can Master Weng and his team really break through the limits of craftsmanship and push the precision to this level?

"Yes! That's right!"

As Dr. Lan Ying's affirmative words came through, Jiang Xia felt as if he had been struck by an electric current and abruptly threw away the microphone.

He let it slam onto the table with a crisp "clang," then Jiang Xia sprang up like a spring, fiercely swinging his fists at the air and roaring with all his might:

"It's done! It's done! Master Weng! Amazing! Absolutely amazing! A true hero! This is a monumental achievement! I must recommend Master Weng for recognition! The highest honor! He absolutely deserves it!"

He was so excited that he spun around twice on the spot, his face flushed red, and the veins on his forehead bulging. Only then did he suddenly remember that the call was still going on. He hurriedly picked up the receiver, but his voice was still sharp and shrill from extreme excitement:

"Dr. Lan Ying! Aunt Lan Ying! You are all amazing! Comrades, you are all outstanding! You are all outstanding! You should all be commended! You are all great heroes!"

As she shouted, tears streamed down her face, splashing onto the radio's casing and leaving a small wet patch.

He knew all too well what that 10mm meant.

The "semiconductor plan" that the US is currently making a big fuss about is still struggling with the manufacturing methods of integrated circuits. It wasn't until the timeline reached the "1970s goals" that they dared to mention 10nm!

We've already crossed the threshold that they'll only be able to reach in ten years!

We're not following, we're leading!

It is truly number one in the world!

Jiang Xia was so excited that he became incoherent. A bellyful of praise choked within him, yet he couldn't find the right words to express his boundless pride. Ultimately, all his words coalesced into the most direct and surging cry:

"Aunt Lanying! Do you know what this means? It means we are number one! We are number one in the world!"

There was a moment of silence on the other end of the microphone.

Then, it was as if a long-accumulated volcano had suddenly erupted!

Deafening cheers, applause, and even the sound of someone slamming their fist on the table surged through the microphone like a tsunami!

Several voices could be clearly heard shouting excitedly, "It's a success!"

"We did it!"

"Number one in the world!"

"Long live the motherland!"

Yes, our lovely researchers don't know what this 10mm actually represents, but they're happy to hear that it's the world's first!

Because right now, China desperately needs this kind of number one...

Amidst the noisy background noise, Dr. Lan Ying's suppressed sobs could be clearly heard.

As a leading figure in the semiconductor industry, she is more aware of the significance of this first place than other researchers.

She laughed and cried at the same time, her voice broken but unusually clear: "Yes! Xiao Jiang! You're right! We...we are number one in the world!"

We've left them...at least...at least ten years behind!

This is a 'chip' that we developed ourselves!

"They're our own!"

ten years!

Jiang Xia silently recited the number in his mind, overwhelmed with excitement.

He knew that, following the original trajectory, the famous Intel 4004 across the ocean would not be released until 1971, with a feature size of 10 micrometers.

Now, our researchers, with their amazing perseverance and wisdom, have advanced the practical application of large-scale integrated circuits by several years, reaching the world's most advanced level!

This is not only a technological breakthrough, but also a magnificent triumph of independence and self-reliance!

How could this not fill one with ecstasy! How could this not bring tears to one's eyes!

…………

After the initial excitement, Dr. Lan Ying followed up with a teasing smile: "Jiangda engineer, you've disappeared by now. At this historic moment, you can only hear the sound from thousands of kilometers away, and you can't even get a chance to solder a pin to the first chip. Don't you regret it? Aren't you upset?"

"Aunt Lanying, please stop teasing me! It doesn't matter who solders the pins, the real skill is in getting the chip working! I'm just happy! By the way, has the performance been tested? What were the results?"

When it came to serious matters, Dr. Lan Ying became serious: "The first step was to do an appearance inspection. We used a microscope to look at the metallization layer and the wire bonding. We didn't find any cold solder joints or broken bonds, and the package didn't leak air. We passed this stage."

"The second step was to measure the static parameters. We applied a 5V operating voltage to the chip and measured the input and output current of each pin. The leakage current was controlled below 50nA, which was better than we expected, and the static power consumption also met the standard."

"For dynamic function testing, we built a test circuit and input NAND and NOR gate logic signals. The output completely matched the design. Even the flip-flop, which is most prone to problems, could achieve a switching speed of 1MHz, which is more than enough to handle conventional signal processing..."

"We are currently conducting high and low temperature stability tests, which is quite time-consuming. The temperature has now reached around 50 degrees Celsius..."

……

Watching Jiang Xia begin discussing professional issues with the other party, Old Wang sighed helplessly.

He was hoping to use this radio to contact his headquarters directly, but now it seems he won't be able to benefit from this advanced technology.

Ugh, forwarding regular calls to the headquarters is such a hassle...

After what seemed like an eternity, a voice finally came from Old Wang's right hand, which was almost stiff from holding the microphone:

"What's the matter?"

"Uh, I'd like a file on the gold theft case..."

"Fuck off!"

"Okay! Alright..."
