Chapter One Hundred and Two

In recent years, due to the reduction of the feature size and the improvement of the integration of VLSI devices, the surface roughness of monocrystalline silicon wafers as substrate materials has become more demanding.

Therefore, Haiyue Company has introduced a number of high-precision polishing machines from abroad, the purpose of which is to produce higher-precision silicon wafers, so as to avoid being eliminated by the market due to backward technology.

It's just that the equipment was shipped, but on the way to use, Haiyue Company ran into trouble.

Because, in the actual production operation, they found that the accuracy of the polished silicon wafer did not reach the value they expected.

Even, there is a lot of difference.

It's just a little bit more accurate than the silicon wafers they produced before.

This makes the leaders of Haiyue Company hurt a lot!

They are a small company with a registered capital of only more than 500,000 yuan, and they can't withstand a big toss.

As a result, I finally made up my mind to spend hundreds of thousands of dollars to introduce a batch of polishing machine equipment, but I don't know what went wrong, and the accuracy did not meet the requirements.

For silicon wafers, the higher the accuracy, the more expensive the corresponding market price.

But now the silicon wafers produced by Haiyue's polishing machines are not only unable to increase the price on the basis of the original, but also even higher than the original in terms of cost!

This made the top management of Haiyue Company unable to sit still.

equipment, it should be fine.

It's just that there may be some mistakes in the way of use.

So, I began to find someone to come to the company for technical guidance, hoping to solve this technical problem.

"So, why did your company find me?" Gu Lu turned his head to look at Manager Lin.

"Because there is no money. Gu Lu's question was very real, and Manager Lin's answer was also very realistic.

Gu Lu: "......"

And so it is.

Other people are tens of thousands of dollars bigger, but Gu Lu, the price is very cheap.

Once, only a thousand.

As for the night......

No, no, without this thing, everyone pretends not to see it!

Anyway, a cheap and high-quality company like Gu Lu is the best choice for the current poor Haiyue Company.

Moreover, it was a candidate personally recommended by Academician Guo.

Even though Gu Lu looked young, with Academician Guo backing him, Manager Lin didn't dare to take it lightly in the slightest.

…………

Haiyue Semiconductor Materials Co., Ltd.'s factory is built in the suburbs, after all, the land in the urban area is too expensive, and it is not at all affordable for a small company like them.

After driving for nearly an hour, Gu Lu saw the gate of the factory.

Haiyue Company covers a very small area, at most seven or eight hundred square meters.

A dilapidated five-story building and a workshop of more than 300 square meters are all it has.

The factory doors are the two large iron gates that are not very common.

Seeing the car parked at the door, the doorman who was sitting on the recliner behind the door basking in the sun got up lazily, clicked and opened the door with a cigarette.

"Dongzi, go home at night to eat, if you don't go back, I won't let your mother cook for you?"

Manager Lin glanced at Gu Lu embarrassedly, rolled down the window and said, "If you don't go back, you can just eat." ”

Manager Lin drove the car to the downstairs of the five-story building, "Mr. Gu, it's here." ”

The two got out of the car.

Gu Lu looked at this barren factory everywhere and smiled helplessly.

It seems that this company is really miserable at the moment!

"Mr. Gu, do you want me to take you upstairs to rest first, and then find two employees to introduce you to the specific situation?" Mr. Lin looked at Gu Lu.

Gu Lu raised his wrist and glanced at the time, and shook his head slightly, "No need, let's go directly to the workshop." ”

"It's always clearer to see with your own eyes than to hear someone else's dictation, isn't it?"

"Then, Mr. Gu, please come here. Manager Lin led the way in front, and Gu Lu followed behind.

Walking into the workshop, the cool air pavements the surface.

The smooth and bright cement floor, the orderly placement of various large-scale equipment, and the sound of various mechanical friction and rotation made Gu Lu finally have the feeling that this is a high-tech material production company.

Manager Lin pointed to the neatly placed row of blue and white polishing machines in the innermost part of the workshop, and said to Gu Lu, "That's the batch of polishing machines we imported from the United States." ”

"Hey, no one is using it?" Gu Lu saw that there was no one in front of the polishing machines, and sighed lightly.

Manager Lin explained with a wry smile, "The cost is high and the accuracy is not up to it, so we are still using the previous polishing machine for operation." ”

Gu Lu nodded, indicating understanding.

"But it's impossible for us to put these hundreds of thousands of things here to eat ashes, so next, please Mr. Gu. Manager Lin's pleading tone.

"Just leave it to me. "Take people's money and eliminate disasters for others.

Besides, it's not too energy-consuming, so Gu Lu naturally won't refuse.

"Lao Huang, come here!"

Manager Lin shouted to a worker who looked to be nearly fifty years old standing in front of an instrument with a notebook to record data.

"Okay, Manager Lin, wait a minute, I'll finish these numbers. After recording the data, Lao Huang put the notebook in a small iron box and walked over.

"Lao Huang, this is the expert I invited to provide technical guidance. ”

"Mr. Gu, this is Master Huang from our workshop, who has worked in a state-owned factory for several years before. ”

Manager Lin introduced the two of them with a smile.

"Hello!"

"Hello, hello. ”

Gu Lu and Master Huang's big rough hands shook together.

"Mr. Gu, let's take a look at the equipment specifically, it just so happens that Master Huang is here, I can give you an introduction. ”

With that, the three of them came to the polishing machines.

Gu Lu first squatted down, looked at the label attached to the device, and then smiled, "Mi domestic Buehler Phoenix Bets polisher?"

Buehler Phoenix Bets polishing machine, polishing pressure of 2N, speed of 200r/min, polishing time of 30 minutes, can be said to be one of the highest precision polishing machine equipment in the international field.

Hearing Gu Lu's words, Manager Lin nodded with a wry smile, "That's right, it's this model of polishing machine, at that time, we found out that the surface roughness of the silicon wafers polished by this equipment can even be reduced to the nanometer level, so we gritted our teeth and bought twenty units in one go......!

This type of polishing machine costs 2,000 US dollars, 20 units, that is more than 200,000 yuan!

But now it can only be thrown in the corner of the workshop to eat ashes.

Gu Lu raised his head and asked, "Then what is the accuracy of the silicon wafer you get after this mechanical polishing?"

"Best once, 1.06 nm. This time it was Master Huang who answered.

1.06nm！

This data is not right, it is very wrong!
