MTL - The Return of the Black Technology of Immortal World-Chapter 59 structure

With the support of spiritual consciousness, the refiner's purification steps can naturally be perfect, to the extent that there are no impurities.

This step is actually just the beginning, it is equivalent to steelmaking to produce a piece of cast steel, and then various processing is required to turn it into a useful component. Of course, this thing is much more complicated than cast steel.

After the monocrystalline silicon is pulled into a silicon rod, it must be cut into slices of a few tenths of a millimeter. The specific thickness varies according to the size of the silicon rod. The larger the diameter of the silicon rod, the greater the thickness. Engraving machine, through a series of processes such as spin-coating photoresist, exposure, etching, plasma sputtering, etc., turns high-purity silicon wafers into silicon chips.

The same is true for the base material of Lingyu. After the high-purity single crystal silicon is purified, runes must be carved in it to become a jade slip.

However, what Yang Qing needs is only the base material, not the jade slips, so even if the silicon wafers on Blue Star are not pure enough, they are barely usable. This is what Yang Qing can think of and can still buy. Two The world is connected to the material now.

Fortunately, he didn't buy a large wafer larger than twelve inches. Several chip foundries couldn't make the difference. He could only order ten six-inch electronic-grade silicon wafers online through Xiao Ai. Dongxi has been mass-produced in China. Compared with large-size wafers, it is far inferior in terms of purity and the number of divisible chips. Therefore, there is no cost-effectiveness in the competition of foundries.

However, it is used to manufacture some chips or analog chips that are not sensitive to the process, and can occupy a place in the low-end market by virtue of the advantage of low price, which is why Yang Qing can buy them.

However, because the silicon wafer is very thin, so thin that it is not even a millimeter thick, it means that Yang Qing cannot use ordinary methods, such as when he was in the wild, to directly carve runes on it with a carving knife. Once it goes down, the whole wafer is broken directly.

Therefore, if you want to process these wafers, it is best to need a set of chip processing equipment such as a lithography machine. However, in addition to the relatively high requirements for the integrity of the runes, the runes are not sensitive to the spatial distance. The 10-micron-level photolithography machine of the century can meet the requirements.

But if it's just an experiment, it doesn't need to be so troublesome at all. Take the copper wire, bend it into the lines of the rune, and then solder it together with solder to form a basic rune.

The simplest way to build the conversion spirit array is six runes, and it is still a flat rune array. This is why Yang Qing was able to get enough to practice in the most primitive environment in the wilderness.

This rune array really doesn't have high requirements for the base material, especially when he only needs to solve whether it can be done, Yang Qing simply decided to stick the copper runes on the wafer with glue, one by one , the two wafers cover the entire rune array, and a complete rune array is made, just like what he did in Honghuang back then.

Of course, due to the extremely low resistance of the copper wire, if the power supply is connected directly, a short circuit may occur before the current is converted into spiritual energy, so a sliding rheostat is added to adjust the current, which was not so delicate at that time. It can only be as simple as possible, but now these components are already standard parts, completely inexhaustible, and can be bought at any time, so it is natural to make them more beautiful.

After thinking through the steps of the experimental design in his brain, it was already lunch time. Excessive consumption made him a little dizzy from hypoglycemia, so he subconsciously told Xiao Ai to order takeaway for him.

At this time, he remembered that there were two of his own employees outside, and they hadn't eaten. Although lunch was not mentioned when signing the contract, as a conscientious and rich boss, he still Decided to provide them with free lunch.

Tapping the table lightly, Xiao Ai's voice came from next to my ear.

"Master, what's the matter?"

"You inform the outside and let them order takeaway by themselves. The company will reimburse you for less than 100 yuan."

"Okay, master."

After finishing speaking, Xiao Ai's voice disappeared from her ears, and two small windows were opened on the computers of the two people outside at the same time, and they made a coughing sound similar to that of a penguin when sending a message.

Of course, this is not a penguin, but an instant messaging software written by Xiao Ai for internal communication in the company. It is only a few megabytes in size, but it is perfectly compatible with computers and mobile phones. It also has powerful office communication capabilities, which is not in any mainstream in the market. under the instant messaging software.

However, this kind of pop-up window did not arouse the surprise of the two people outside, because this morning, the window has popped up many times. Generally, the appearance of the window means that the boss hiding inside has something to order.

But this time it was different, Yang Qing could clearly hear the faint cheers coming from outside, and after a while, a window popped up on the computer in front of him.

"Boss, do you need our help to order takeaway?"

Probably because he just went to work~www.novelbuddy.com~ He is not familiar with the company, especially his boss, the two girls still dare not come in to chat with him blatantly, so they can only communicate through the chat software.

"No, I've already sold out my takeaway orders. When you order takeaways, be careful to choose hygienic ones, so as not to spoil your stomach."

"Thank you boss, we will pay attention!"

After the communication was completed, the dialog box slowly disappeared. The difference between the instant messaging software written by Xiao Ai and the Penguin and Weichat on the market is that there are no emoticons or emoticons. Don't think about the picture, according to Yang Qing, office software, it's better to be pure.

Yang Qing thought about it, and then called Zhao Yuxi who was running around outside. Although she was a tool person, she was working outside for the company after all. As the company's boss, he still wanted to express his concern.

"Hi Mr. Zhao, how are you doing this morning?" Yang Qing asked after the call was connected.

"Hi Mr. Yang, don't mention it. It was okay when I told the business people at the beginning today, but as soon as the materials were handed in, they changed and said that they need to study it. I waited all morning, but I haven't waited. their leadership."

Hearing Zhao Yuxi's words, he couldn't help laughing wryly. Those people really acted fast enough. It took only a few days for him to change the publisher of the software to the company, and their tentacles had already stretched out. According to their plan, it was obviously In order to curb my cash flow, it is better to come to the door to raise funds when I can't survive, so as to take a bite out of my fat.

"According to the current public opinion, this is all expected. If you really can't find someone, forget it. Anyway, it's still early, and we can handle it before we file taxes. Why don't you come back and talk about it."
