Ever since the roller mill was completed, the precision of the fab had changed from pulling the single crystal column to the step roller mill.
Soon, dozens of single crystal segments had been rolled and were waiting for the multi-wire cutting machine to slice the single crystal segments.
For the next few days, Su Chen spent every day in the laboratory assembling the machine.
Multi-wire cutting machine, chamfering machine, refiner, engraving machine…
Su Chen worked overtime every day and successfully completed the machines according to the blueprints.
The rolled single-crystal segments were sliced and then mechanically polished to flatten the surface and reduce the thickness to 775 millimeters.
Then, he used a chamfering machine to make the edges into right angles.
Then, he used the refiner to remove about 10 millimeters of thickness again.
Finally, it was placed into an engraving machine to dissolve the impurities.
This was the step that could be done with the current chip.
However, he still needed two more steps to put it into the photolithographic machine.
The first step was chemical mechanical polishing, followed by applying resist.
Today's task was to polish the crystal!
At this moment, the polishing machine was officially completed!
Experimenting with electricity!
"Report, the voltage is normal. There is no damage between the various components.”
"Activation successful!"
After connecting the machine to the power source, the machine lit up in one go!
Everyone cheered.
"It's finally done. In this case, we can carry out the processing experiment when we reach the clean room tomorrow!”
"Yes, if tomorrow's experiment can be successful, our project will be a success!”
"There will definitely be no problem!"
"Shh, look, Su Yu went out again!”
"It's already ten o'clock. He must be reporting to his girlfriend again! You'll definitely be a henpecked husband in the future!"
"Nonsense, this is called caring and responsible for the Gu family!! He told his girlfriend that he was safe every day. It was really reassuring to have such a boyfriend!”
"Yeah, Su Yu's phone calls are getting longer and longer these days!”
“……”
Su Chen didn't hear her colleagues 'discussion at all.
Over the past few days, the machines that he had developed had all been successfully lit up in one go!
He realized that Zhou Shuyi was right!
Could it be that her words really carried the law?
"Look, I already said that my words are the law! Tomorrow, you will definitely succeed on your first try!”
"I'll cook dinner for you tonight and pick you up downstairs!”
On the other end of the phone, Zhou Shuyi looked a little excited.
"Then if I can't go back, wouldn't you have done it for nothing?" Su Chen smiled faintly.”
As soon as he finished speaking, Shu Nainai jumped out from the side.
"Brother-in-law, come back quickly. The boss cooks the same dishes every day. We're about to vomit from eating them!”
"That's right, Brother-in-law. Sister Zhou doesn't even let us order takeout. If we continue eating, I'm going to turn into the shape of that dish!”
Zhou Shuyi pushed the people on both sides away with a look of disdain.
"Are you done dancing? Go back and do a live broadcast, or your wages will be deducted!”
"Wow, black-hearted boss!"
"Nero Zhou!"
Zhou Shuyi's face darkened when she heard Egg Bao's wail.
Her surname was Zhou!
True Zhou Flay!
These two ingrates!
He lived in Tomson First-Class Restaurant and ate such delicious food, yet he still called himself Nero Zhou!
He really should be punished!
The corners of Su Chen's mouth curled up slightly.
"Alright, I'm going back to work. You should hurry back to the live broadcast too.”
"Okay, I'll wait for you tomorrow!"
Su Chen put down the phone.
For some reason, he was actually looking forward to tomorrow's dinner.
Recently, he was already a little tired of the food in the laboratory.
……
The next day.
The equipment was placed in the clean room.
This was because after the final step of polishing, the chip needed to be protected from dust. Otherwise, if it was contaminated with dust, it was likely that the dust would be sealed in the process of applying the resist.
When it came to photolithographic, the dust of hundreds of millimeters would hinder the nano-level photolithographic technology.
Su Chen and Yang Ping changed into dust-proof clothes. After being heated at 360 degrees without any blind spots, the dust on their bodies was completely removed and they officially entered the laboratory.
Soon, the laboratory began the final experiment--chemical mechanical polishing of the chip.
After a few researchers finished adjusting the equipment, they took out a piece of chip from the sealed box.
At this moment, the color of the chip was still slightly dark.
After fixing the chip onto the polishing machine, everything was ready.
"Start the experiment."
The central control room gave the order.
A few researchers began to operate the knob on the machine.
Soon, the chip began to spin in the card slot.
In fact, this step was also considered polishing, but it had to be completed after polishing.
Soon, under the grinding of the three brush heads, the dark and heavy Si chip began to emit a luster!
A few minutes later, the surface of the chip turned into a perfect mirror!
After the polishing was completed, the tentacles of the coating machine sucked the chip and placed it into another slot.
The tray began to rotate, and the resist began to spread out from the suction cups of the tentacles.
A layer of black resist was evenly spread on the chip.
Because of the chamfering, the resist was very uniform, and there was no deposit at the edge!
The best way to inspect this 12-inch crystal was to put it into a photolithographic machine and directly perform photolithographic!
Therefore, without stopping, the crystal was sucked into the photolithographic machine.
After a few minutes of waiting, a photoetched crystal was born.
It was only at this point that all the engineers cheered!
"It's a success!"
"Success in one go!"
"Oh my god, I can't believe that we actually have the raw materials for the photolithographic machine and chip!”
Soon, the chips began to be polished and coated.
Not long after, the detailed data was available.
"Report, the loss rate of the 12-inch production line is only 1.2%."
"The loss rate is 7.9% lower than overseas!”
This number was undoubtedly shocking!
This was because a loss rate of 1.2% was too low.
It was a very common thing for a chip to crack because it was too thin!
And what did 1.2% loss mean?？
One to two chips would collapse for every 100!
It was not that simple overseas!
The few academicians were extremely excited!
This success rate was simply shocking!
Actually, the biggest reason was the idea of the multi-wire cutting machine!
It was an extremely smart idea!
Now.
With the 12-inch chip manufactured domestically, the domestic chip manufacturing industry would no longer have to worry about being stuck!
Moreover, the cost of the chip would also drop significantly!
It was only now that China's chip industry was truly on the same level as foreign countries!
"Little Su, you're a genius in the semiconductor industry!”
"1.2% loss rate! Amazing! This time, Su Chen had an irreplaceable role in the 12-inch chip technology!”
"If it weren't for Little Su's blueprints, we would probably be unable to catch up to foreign countries in five years!”
