Chapter 784
Although they were very sure of Xu Hao's ability and his grasp of the theoretical system in the field of lithography, they did not have much experience in lithography. However, they knew that the theoretical knowledge of lithography was related to the process of developing high-precision chips, but there were also differences. Therefore, they did not dare to jump to conclusions and believe that the solution provided by Xu Hao was definitely feasible. However, they knew more clearly that, except for the solution provided by Xu Hao, they had no choice. Whether this lithography project could eventually develop the high-precision chips they expected was also related to the future development of Longguo and all aspects. Although these senior officials and authoritative experts and scholars of Longguo were not afraid of failure, this was a matter of urgency after all. This also made them cautious and uneasy. Xu Hao's explanation continued. But now, every time he said the next step, he would say it after thinking it over and over again and thinking that it was foolproof. "The photoresist is coated, and the photosensitive material "photoresist" or "photoresist" is coated on the wafer as a template for the subsequent photolithography process."
"The circuit pattern on the chip is projected onto the photoresist layer using a photolithography machine to form a graphic template."
"The light beam is projected onto the wafer through the mask, and the photoresist undergoes a chemical reaction under the irradiation of the light beam to form a circuit pattern."
"The unmasked part of the photoresist layer is etched to remove unnecessary materials and form a circuit line. Etching is divided into dry etching and wet etching."
"One is to use ion implantation equipment to implant ions of specific elements into the wafer to change its electrical properties to meet the needs of the circuit."
"One is to package the manufactured chip to protect it from the external environment. environment, and facilitate subsequent testing and application. ""
...
Time flies by.
Under Xu Hao's plan.
These lithography experts successfully completed every step as Xu Hao said.
Now it's the last step.
And this step also made everyone present completely hang up their hearts.
Because this last step is to determine whether the lithography machine can produce chips that meet their testing needs!
This is a long process.
There was a deathly silence in the laboratory.
Everyone stared at the running lithography machine and a group of machines for making chips.
This is not only related to whether the plan provided by Xu Hao is correct.
It also determines whether this lithography project is successful.
"Will it succeed? After this lithography project, will my Dragon country completely make up for the largest missing industrial chain in my Dragon country?"
"The last step, success or failure depends on this!"
"Is there a chance, Dragon country ancestors, bless us!"
"I hope everything will be the best result we hope for! ”
“Dear Dragon Country’s lithography experts, go for it! I believe in you!”
…
The Dragon Country’s high-level officials and authoritative experts and scholars outside the venue remained calm.
But their eyes were filled with self-evident nervousness and expectation.
However.
In their hearts.
What will be the result of this lithography project.
These lithography experts are all heroes of Dragon Country.
At least.
They have left the most critical experience for future Dragon Country lithography projects.
Without their efforts today.
There will be no future development of Dragon Country’s lithography!
…
And those experts who participated in this lithography project.
Now they are even more cautious and nervous.
Although they also know that this is the first time to develop high-precision chips.
The final result is likely to fail.
But in terms of Dragon Country’s current national conditions.
They have more expectations and wishes in their hearts.
"Buzz..."
A roar suddenly sounded in the laboratory.
This roar instantly pulled everyone's mind over.
Because they knew the test results of this lithography project were out.
The chip that was finally born after all kinds of difficulties was finally developed!
And this chip carries their things.
There is hope, sweat, and it has a direct impact on the future of Longguo!
This chip is the product that all the senior officials of Longguo and a group of authoritative experts and scholars present have been looking forward to for a long time.
It is also the work that these lithography project experts have worked hard for a long time.
It is also related to whether this lithography project is successful and whether the solution provided by Xu Hao is correct.
In an instant.
Everyone present flashed nervousness and expectation in their eyes.
No one moved.
No one dared to look at this condensedA chip with too many things.
"Huh..."
Finally.
Xu Hao took a deep breath.
Slowly walked towards the chip.
As Xu Hao got closer.
Everyone's heart was getting tighter and tighter.
Curiosity, expectation, excitement and tension occupied the hearts of everyone present.
And as Xu Hao continued to move forward.
Those lithography experts could no longer suppress their tension and curiosity.
They rushed forward.
Followed Xu Hao and approached the chip.
In the tense and expectant eyes of everyone.
Xu Hao carefully picked up the tray containing the chip that was invisible to the naked eye.
"Huh..."
After Xu Hao took a deep breath.
He handed the tray in his hand to the person in charge of the lithography project behind him.
He said a little tiredly.
"Take it and measure it to see how accurate this chip is..."
Zeng Xiangsheng, the person in charge of the lithography project, also took a deep breath.
Try your best to relax your tense nerves.
Then you carefully take the tray.
Walk towards the machine for measuring chips.
As Zeng Xiangsheng, the general manager of the lithography project, gets closer and closer to the machine for measuring chips.
The lithography experts who followed him felt their brains in a mess.
All kinds of emotions surged in it.
They no longer wanted to think too much.
They didn't want to endure this tiring waiting process.
They just wanted to fast forward to the moment when the chip measurement results came out.
...
A group of senior officials of Longguo and a group of authoritative experts and scholars outside the venue also came directly to the glass of the experimental table.
Their expressions were serious and full of expectations.
No one spoke.
But everyone present could understand each other's feelings at this moment.
Because they all wanted to witness whether this final result can change Longguo's existing industrial chain.
Whether Longguo can once again not worry about other countries.
They all want to witness whether this chip, which is related to too many things, can successfully pass this final test.
Time passed by minute by minute.
Everyone stared at the chip measuring tool.
The waiting process was long and painful.
The emotions in everyone's heart became stronger and stronger.
Finally.
With a "ding" sound from the measuring machine.
Everyone knew that the test results were out.
They all looked at the display screen of the measuring machine at the same time.
It was clearly written on it.
"2 nanometers!"
