According to the two factors of light and temperature, Lao Gao did a series of experiments, and finally found out the decisive factor light!

He simulates sunlight with a flashlight, illuminating the light-reflecting area of the monocrystalline furnace.

In the end, a silicon wafer with a purity of 99.01% was really extracted!

Moreover, he found that according to the intensity of the light, the purity of the extract also varies by amplitude, and its range is between 99.01% ~ 99.09%!

……

When everyone learned of Lao Gao's experimental results, they all poured into his laboratory!

He explained the principle of illumination!

Then in front of everyone, I did three experiments and found that the data was between 99.01% ~ 99.09%!

When they saw the results with their own eyes, they were thrilled!

After half a year, the purity of their silicon wafers finally exceeded 99%!

With Lao Gao's amazing discovery, as long as they follow this direction to study, I believe that it will not take long to study silicon wafers with higher purity!

At that time, with the lithography machine research department, they will be able to produce 17nm chips by researching a 17nm lithography machine!

The more they think about it, the more excited they become, and the more they think about it, the more excited they become.

"Lao Gao, you're awesome!"

"You're really the hero of our silicon wafer department!"

"Great! Haha......"

“……”

Ding Haibo, the director of the silicon wafer department who was doing experiments next door, heard the cheers here!

Soon he walked over, and he said with a straight face!

"What are you doing, this is a laboratory, don't make a loud noise!"

During this time, he saw the closed research of the lithography machine department and affirmed that they had a major technological breakthrough.

And their silicon wafer department has not made technical progress for half a year, which makes him very stressed!

Everyone saw that it was Director Ding Haibo, and said to him excitedly!

"Director Ding, good news!"

"We've made a technological breakthrough!"

"Lao Gao, he has researched a silicon wafer with a purity of 99.09!"

"We've finally broken through!"

“……”

Ding Haibo heard important information from everyone's gossiping words!

Immediately grabbed a scientific researcher beside him and said!

"What do you say? We have refined 99.09% of the silicon wafers? ”

"Yes, Director Ding, look, this is a test list!"

Ding Haibo grabbed the test list and looked at it!

Sure enough, it shows that the purity of silicon wafers is 99.09%!

Then he looked at another test list, which showed that the purity of the silicon wafer was 99.06%!

He looked at several test sheets one after another, and the purity of the silicon wafers reached more than 99%!

Ding Haibo's excited hands trembled! Babbling!

"Breakthrough! We've finally broken through! Haha......"

"Who came up with this?"

"Director Ding, it's Lao Gao, he researched it!"

Then Lao Gao told what happened!

Ding Haibo heard some coincidental research results, not to mention how happy he was!

So, said to Lao Gao!

"Lao Gao, you prepare, I will immediately organize a meeting of all scientific researchers, and you can make a report to everyone!"

Subsequently, the scientific researchers of the silicon wafer department rushed to the conference room when they heard that there was a major breakthrough!

After Lao Gao explained the new results, everyone was excited, and then they discussed six research plans!

Ding Haibo divided everyone into six groups and studied these six options at the same time.

As long as they find that one of the six middle school plans is feasible, they can focus on breaking this kind of plan!

Ding Haibo believes that it will not take long for them to extract higher purity silicon wafers!

Then, everyone was excited to devote themselves to the research!

On the same day, Ding Haibo told Director Zhang about the major breakthrough in silicon wafers.

Director Zhang was thrilled when he heard this good news!

He didn't expect that at the same time as the breakthrough of the lithography machine in their research institute, the silicon wafer technology also broke through!

In this way, he can complete the tasks assigned by the senior leaders in advance!

……

Kyoto No. 3 Research Institute Lithography Machine Research Department!

With the addition of Qiao Lao and Jiang Fan, there are a total of 80 personnel, and each of them is busy with their work in a tense and orderly manner!

At the beginning, many people were very uncomfortable with Jiang Fan's closed research.

They are in the laboratory 24 hours a day, have special personnel to deliver meals, and sleep in simple beds when they are tired.

Everyone only sleeps 3~4 hours a day, and many people can't stick to such high-intensity work!

But they saw that Xia Xiaoyu, Xu Guangyuan and Niu Xu were like chicken blood every day, and their spirit of not admitting defeat came up!

What surprised everyone even more was that the three of them completed the task Jiang Fan explained very quickly!

Almost crushed all the old researchers here.

The three of them are students who have not yet graduated, and it is the first time they have come into contact with lithography machines, which makes them feel embarrassed!

Especially those self-righteous old researchers, they have been deeply taught a lesson!

It's really the back waves of the Yangtze River pushing the front waves, and the front waves crashing on the beach!

When everyone saw the abilities of the three of them, no one dared to underestimate them.

Sometimes there is something I don't understand about Jiang Fan's task, and I ask them for help!

Qiao Lao has also been tossed enough in the past ten days, after all, he is in his fifties, and his body is a little unbearable.

But seeing that everyone is under the leadership of Jiang Fan, the 7nm lithography machine has made great progress every day, and he has been in a state of excitement!

"Chief Engineer Qiao, you better rest for a while!"

One of the scientific researchers said to Qiao Lao!

"It's okay, I'm not tired!"

"Look at the dark circles under your eyes, you're about to turn into a giant panda!"

"It's about to be developed, where can I sleep!"

Qiao Lao's face was full of excitement when he spoke!

He glanced at Jiang Fan, who was busy checking the equipment, and was indescribably relieved!

He never imagined that under the leadership of Jiang Fan, it would take only ten days for everyone to complete the equipment of the 7nm lithography machine!

Such a speed will definitely shock the scientific research community!

After Jiang Fan finished checking the equipment, Qiao Lao walked up!

"Jiang Fan, like this, your body can still bear it, right?"

Jiang Fan patted his chest and said!

"No problem!"

"It's good to be young! Haha......"

Qiao Lao simply admired Jiang Fan's five-body throw, others stayed up for more than ten days, and their faces were full of haggardness, but his was already as handsome and energetic as ever.

In fact, what Qiao Lao didn't know was that Jiang Fan had a system reward for staying up late!

"Jiang Fan, how long will it take for the lithography equipment to be completed?"

"About 10 hours!" Jiang Fan replied!

When Qiao Lao heard this time, he was immediately excited!

Then he said to everyone!

"Everyone can hold on for another 10 hours, and our 7nm lithography machine will be able to be developed!"

When everyone heard the news, they replied with a rainbow!

"Good!"
