at the same time.

Richard took the sand and entered the Garden of Eden.

Walked into the main laboratory, poured the sand into a funnel-shaped container, began to wash, screen, filter, after a lot of processes, and finally got qualified pure sand.

Transfer the pure sand to another cylindrical container, mix a lot of coke, put it in a special furnace and start heating.

During the heating process, the sand makes a noise. Richard knows that this is the composition of the sand-silica (SiO2), which reacts with the composition of the coke-carbon (C), which will eventually produce a metallurgical grade with a thickness of 98% Coarse silicon (Si) around.

After heating, Richard got enough coarse silicon, without hesitation, and quickly started the second step of processing.The specific operation is to chlorinate with hydrochloric acid and then distill to make polycrystalline silicon with high purity step by step.According to the standard, the purity of the manufactured high-purity polysilicon is 99.999999999%-a total of 11 9s-this is a hard requirement. If it cannot be achieved, the products made afterwards are likely to have certain defects.

After completing this step, after passing the test, Richard did not stop, and began to put polysilicon into a special container to melt into a high-temperature liquid under the effect of high temperature.

After successful melting, put a small grain of silicon crystal silicon into the liquid, and use this piece of silicon crystal silicon as the attachment to let the liquid form a little at the bottom.When the silicon crystals of silicon crystals that were put in and tied up were slowly pulled out, a round bar was formed under the silicon crystals of silicon crystals.This is a single-crystal silicon ingot, also known as a "long crystal". It can be seen that the long crystal is a standard cylinder, and the radius is the same as the silicon crystal that was originally placed.

At this point, the negative of the chip has completed the production stage, and the next stage is the processing stage.

Put away the produced single crystal silicon ingot, Richard stepped, quickly walked out of the main laboratory, went to the machining sector, and then entered the research room.

In the research room, Li Cha put the single crystal silicon ingot on the processing table, kept it in a vertical state, adjusted the mechanical arm to move down, and started precise cutting.

"brush!"

After swinging the manipulator, I saw that the single crystal silicon ingot was immediately cut off, and the cut part happened to be a thin wafer with a diameter of more than ten centimeters.

When the wafer is polished and polished finely, the surface of the wafer is extremely bright, like a mirror, and it has become a qualified wafer-silicon wafer. This is the most basic raw material in the integrated circuit industry.

After cutting the wafer according to a certain specification, it is the original state of the chip, which is the so-called negative film.

At this point, the film production is complete.

...

After the production of the negative film is completed, it is the photoresist and developer that need to be resolved.

Photoresist is a liquid smeared on the negative film. After being irradiated with special light, it will have a special change, and then immersed in the developer to carry out a special reaction to obtain the pattern on the mask.

In general, there are two main types of photoresist-positive photoresist, and negative photoresist.

Positive photoresist is a photochemical reaction that occurs in the exposed part and dissolves in the developing solution. The unexposed part is insoluble in the developing solution and remains on the substrate. The final pattern formed on the substrate is the same as the pattern on the mask.

Negative photoresist is that the exposed part is insoluble in the developing solution due to crosslinking and curing, and the unexposed part is soluble in the developing solution. The final pattern formed on the substrate is exactly the opposite of the mask.

After some consideration, Richard decided to use positive photoresist, so it would be easier to make a mask later.

In this way, Richard started the configuration of chemical reagents.

After that, he was busy for several days, constantly going in and out of the three-story wooden building, and the monitored Maas constantly reported the observation to the wizard Wanan.

...

After a few days.

In the second floor wooden building.

After listening to Ma’s report again, Wan An frowned deeply, very puzzled: "Before, he searched for the blood of demonized creatures, the juice of the plants, and he could barely understand, but today he is looking for what it is called' What does Montaukite's ore want to do?"

Because Mas stayed outside for a long time, he was hungry and groaned, standing in the corner while stuffing the mouth with dried fish, pumpkin pie, etc., and shaking his head in response: "I don’t know the teacher, oh, oh, anyway From the beginning, I thought the guy was weird and completely unclear what to do, huh huh..."

Wanan couldn't help but feel bad, and he was bored when he heard Ma's mouth eating. He turned his head suddenly and looked at him, commanding: "Don't stay here, you go out and keep staring. , Must not let go of any of his actions."

"But..." Mas hesitated for a moment. "Teacher, can I go before I finish eating? I haven't had some good food for days."

"Huh?!" Wanan raised his eyebrows, his expression becoming a little dangerous.

"I!" Mas grumbled, swallowing the food, and dared not talk nonsense, kicking dried fish, pumpkin pie and the like into his arms, crawling and crawling out of the door.

After running out of the door, Maas took a pumpkin pie into his mouth, biting it fiercely, and looked a bit daunting, but he swallowed the pumpkin pie with a "gurgle" and returned to normal.Looking at the wooden building behind him, he breathed a sigh of relief and walked towards the corner of the gathering place.

...

Inside the Garden of Eden.

Main laboratory.

The two liquids of photoresist and developer were mixed in the container. Li Cha carefully observed the reaction and nodded with satisfaction: "It seems that both liquids can play a corresponding role. Then, except for the light source, there is only Mongolia left. The board needs to be solved. However, the mask is a big job."

Well, great work.

The role of the mask is to block the light of the light source, so that specific light can be irradiated on the photoresist coated negative film to produce a specific shape.

The shape on the mask is the shape on the chip.

Therefore, it is necessary to engrave all the magic patterns in the design of "Ecstasy Gloves" on the mask.

"Cracking!"

Richard moved his body, made a series of bone sounds, then walked out the door and walked to the machining sector.

In the mechanical processing sector laboratory, Li Cha found the prepared metal sheet and placed it on the processing table to cut it into 10 cm square specifications.Then adjust the mechanical arm, put on the micro glasses, adjust the focal length, and draw lines on the metal foil.

It takes a long time to portray, and occasionally it stops. After thinking for a while, I continue to portray.

"Shusha..."

In the research room of the machining sector, only the sound of metal cutting echoed, and it was extremely quiet...

Richard is working quietly and meticulously in this quiet...

One minute, two minutes, three minutes...

Ten minutes, twenty minutes, thirty minutes...

One hour, two hours, three hours...
