You fight you ruthlessly, I do my job.

Although Ding Chi didn't know the specific operation of Yin Xian and the others, he could also imagine that he was inseparable from the imaginary enemy. Taking advantage of the enemy's flawless care, it is a good time to work hard, and the company is full of energy, and the progress of the remaining months is very impressive.

Early that morning, Jiao Zhen invited Ding Chi and Zhuge to visit the workshop. Of course, as a non-scientific researcher, the visit can only be on the periphery, only through the glass.

Although they are in the same courtyard, due to the different division of labor and the particularity of high-precision products, Ding Chi rarely goes to the workshop, so he is troublesome and others are also troublesome. For this visit today, Ding Chi was "armed" all over his body - white coat, head cover, shoe cover, gloves, and also reviewed the relevant precautions.

Walking into the visiting corridor, Jiao Zhen raised his hand and signaled: "Boss Ding, Zhuge Lao, please see, this is the wafer making process." The composition of the wafer is silicon, which is refined from quartz sand, and we have a high-purity outer wafer with a purification rate of eight or nine. The silicon crystal rod we purchased directly also saves the previous refining process, so the first step of the procedure is to make a wafer and slice the silicon crystal rod. The thinner the wafer, the higher the yield, the lower the production cost, but the higher the process requirements. Judging from the operation in recent days, this process is very successful, which shows that our equipment and personnel are excellent. ”

Listening to the explanation in his ears and staring carefully at the operation inside, Ding Chi nodded secretly: Yes, it is indeed good. Although he is not professional enough, he is by no means a layman, after all, he has been busy for so long, and he has also interned in the capital Fenzhong Electronics Factory.

The three of them then walked forward, and then moved on to the next process, wafer coating.

Jiao Zhen continued: "The coating film is to apply a layer of photoresist on the surface of the wafer, which is the one that Zheng Gong is taking now, and then dry this layer of adhesive, and then it will be transferred to the lithography machine. Don't look at just gluing, but pay attention to a lot, uniformity, density have strict requirements, this is also an important step to affect the ability to resist oxidation and temperature, it can be said that the difference is a millimeter, no, the difference is nanometer, and the error is a thousand miles. ”

"The next step is lithography, and there are a lot of steps in it, and we can't see a lot here. First of all, it is irradiated with ultraviolet light, not directly, but through a mask and a convex lens to soften the coating film on the wafer. ...... later"

Jiao Zhen gushed endlessly, his face was full of joy, just like a father talking about his child, and his affection was obvious.

It took more than an hour for Jiao Zhen to introduce the "child" to Ding Chi and Zhuge Moran, and sent the two out of the production workshop.

"Boss Ding, Zhuge Lao, today we are going to make the first lithography circuit, the preparations are very sufficient, and the early progress is also very smooth, you two are waiting for the news of our victory. Jiao Zhen is full of confidence.

"Okay, look forward to it. Shaking hands with Jiao Zhen and saying goodbye, Ding Chi and Zhuge silently left together and returned to their respective offices.

Leaning comfortably on the back of the chair, Ding Chi was very comfortable. It's a lot of emotion to think about the difficult start to the current well-equipped and smooth progress.

Leave it for later, work hard, and move on. Thinking of this, Ding Chi sat up straight and continued to deal with the work at hand.

In the midst of the hustle and bustle, the day passed quickly, Ding Chi stretched his waist and prepared to go to dinner.

"Boom, boom", a rush of footsteps suddenly came.

This was followed by a knock on the door.

"Come in. ”

As soon as Ding Chi's words fell, the door opened, and Jiao Zhen walked in quickly. Seeing the other party's expression, Ding Chiton had a bad premonition.

Sure enough, Jiao Zhen opened his mouth and said "lithography failed".

Although he was a little disappointed, Ding Chi immediately said: "It's normal, how can you succeed once." ”

"When cleaning silicon wafers, I stared at the whole process from chemical cleaning to rinsing to drying, pre-baking, primer coating, photoresist coating, pre-baking, and alignment. However, in the end, the lithography line structure was deviated and did not meet the requirements at all. When Jiao Zhen said this, he let out a long sigh: "Alas...... Boss Ding, I'm also ......."

Ding Chi waved his hand again and again: "It's okay, it's okay, it's normal, check and fill in the gaps, and further improve." ”

After a few sighs in a row, Jiao Zhen hurriedly left to find out the reason.

At this moment, Zhuge came silently, and he also heard about the failure of lithography. The two ran to the cafeteria together, chatting as they walked.

Zhuge silently raised his hand and pointed: "I saw Jiao Zhen from afar just now, walking by from there with a roar, without raising his head, it was obvious that he was on fire." During this period of time, Jiao Zhen seemed to be inflated, with endless energy, working fourteen or fifteen hours a day, and almost never left his post except for those few hours of sleep. During this time, the entire research and development has also progressed rapidly, and his heart is higher, and he is naturally uncomfortable if he doesn't make it. ”

Ding Chi nodded and said, "Yes." Just now I advised him not to get angry in a hurry, but apparently he didn't listen, and his mind was full of work. When you have time, you can also help persuade you not to tighten the strings so tightly, otherwise you will definitely not be able to stand it for a long time. ”

"Look at the time, I'll talk about it in a few days, he won't listen to it now, and it's likely to backfire. ”

While talking, the two entered the cafeteria.

After dinner and a casual walk around the yard twice, Ding Chi returned to his house and dealt with the work at hand.

At about eleven o'clock in the evening, when Ding Chi was about to rest, Jiao Zhen came again.

"We cross-swapped, checked all the procedures, didn't find any problems with the previous process, and now we're working on the final step – removing the photoresist. They are looking at the operation steps and arguing for the rationality of the operation method. Boss Ding, don't worry, even if you don't sleep for a few nights in a row, you must find out the problem. Jiao Zhen gritted his teeth.

Ding Chi pointed to the clock and said, "It's almost twelve o'clock, let everyone rest, it's not good to hold on like this." It's still the same sentence, it's the first time to get this, it's too normal, there's no need to dwell on it. ”

"I can't sleep, how can I have the heart to sleep? I'm here to tell you that we will definitely find out the problem as soon as possible, and we will definitely take it as a warning. Okay, you go to sleep, I'm leaving. After Jiao Zhen finished speaking, without waiting for Ding Chi's reply, he turned around and left.

Ding Chi took two steps, thought about it, and turned back to the house.

"It's embarrassing, whether that's an advantage or a disadvantage. Ding Chi shook his head lightly and entered the bedroom in the back room.

Although it was very late, Ding Chi couldn't sleep when he was lying in bed, tossing and turning. It is said that I have a very light view of today's events, and I don't take it to heart at all, so why can't I sleep?
