Black Hole Lithography Machine Company.

The parts that Pu Weicai needs Wei Ming to help with are mainly related to optical lenses.

In particular, the reflective film material on the surface of the optical lens requires a purity of more than 8 nines.

However, domestic related material companies can only achieve the purity of 4 nines, which is still four orders of magnitude.

In order to improve the reflective efficiency, Weiming can only use Xiaohei to absorb impurities and purify the material, so that its purity is infinitely close to 100%.

This is a slow work, eliminating impurity molecules one by one, and it can't be purified much in a day.

Later, scientists thought of an ingenious way, that is, to dissolve the reflective film material in a special organic solution, and most of the impurities can not be dissolved, so the impurities are precipitated, and then heated with a special organic solution to precipitate a higher purity reflective film material.

After repeated operations like this, the purity of the reflective film material can be increased by more than 11 nines, which is three orders of magnitude higher than that of foreign materials - this is also the reason why the energy utilization efficiency of Tyrannosaurus EUV can be more than three times higher.

However, after many times of use, the purity of the special organic solution itself will decrease, which will affect the purity of the reflective film material, and the special organic solution must be purified.

This requires the production of a special molecular sieve, the pore size is extremely small, only the organic solution molecules are allowed to pass through, and none of the other molecules can pass through, and the purity can even reach 100% at the theoretical level.

Therefore, in order to solve the problem of reflective film, Wei Ming had to make a batch of organic solution molecular sieves and use Xiao Hei to lay small holes one by one.

Since the diameter of the small pores of the molecular sieve is just about 1 nanometer, Qianwei Ming needs precise control to drill up to 10 billion holes a day.

But now the range of the horizon is just 1 nanometer, as long as you close the gravitational radius, close your eyes and punch holes frantically, 1 trillion holes have been drilled in just ten minutes.

The efficiency has increased more than 10,000 times.

In just two hours, he made a molecular sieve that was enough to use.

In fact, many of the things that are done in the high-tech field are actually like this.

A lot of chemical materials with close to 100% purity are required.

Parts that require close to zero error.

The curvature of the lens needs to be infinitely close to a mathematical formula.

Even the water used to cool the lithography machine must be 100% pure water without any impurities, so that the cooling performance of the lithography machine remains linear and stable and not affected by impurities.

and the working environment of some subsystems, preferably an absolute vacuum where not a single air molecule exists...... It just so happens that Black, who is able to devour everything, can create the closest environment to a vacuum.

The metal tin droplets used in the light source system must also ensure that their purity is 100%, so as to reduce the generation of stray light.

Using the vacuum container centrifugation method, Wei Ming helped get 100 kilograms of high-purity tin ...... That's enough for twenty lithography machines.

It's been a busy day.

Once all the backlog issues have been resolved.

It was past 8 p.m.

"Thank you Mr. Wei, this batch of problems will be solved, you will have no problem if you don't come by the end of the year, at least you can manage it for half a year."

In the factory cafeteria, Pu Weicai, who was eating overtime meals together, looked up and said.

"Lao Pu, from November last year to May now, it's been almost half a year, why hasn't the new Tyrannosaurus EUV resumed shipments, your efficiency is still not very good, some voices on the Internet say that we can't continue to ship, the three Tyrannosaurus EUV is the swan song, and there are many voices mocking and singing." Wei Ming said unhappily.

"Mr. Wei, this month, I promise to ship a batch of two Tyrannosaurus EUVs, all of which will be delivered to Blu-ray Company."

Pu Weicai said: "In June, two more units will be delivered to Blu-ray Company, and then from July to December, at the rate of two units per month, Longyao Company's chip foundry that has almost risen from the ground will be delivered to Tyrannosaurus EUV to achieve timely docking and cooperation." ”

"In this way, a total of up to 16 Tyrannosaurus EUV can be delivered this year, if the follow-up work efficiency and production capacity are improved, it is not impossible to deliver 20 units, and many employees complain that the six-fold discount price is too cheap, which will lead to a significant reduction in bonuses, which obviously affects their enthusiasm for work, but fortunately, Mr. Wei agreed to increase the sales reward ratio to 50%, and then run more, so the motivation is still relatively sufficient."

For example, the number of employees who take the initiative to apply for overtime has increased, and two shifts have basically formed.

"It's good to be motivated."

Wei Ming nodded: "Recently, there are more and more people who want to see jokes on the Internet, and they are all looking forward to the failure of the Black Hole Group, and there are fewer and fewer voices of encouragement and support, and there are more and more yin and yang weirdness and schadenfreude. ”

"Fortunately, the morale of the employees looks good, so that you can announce a good news to them tomorrow to boost the morale of the employees, the No. 1 real estate of the Black Hole Real Estate Company, a total of more than 1,200 houses, will be opened next month, originally this real estate was intended to be used for commercial purposes, sold to social customers with housing needs at a price of more than 30,000 square meters."

"But I have changed my mind, I plan to sell all these commercial houses to the employees of the Black Hole Group, and the price per square meter will not be higher than 15,000, which is more than half cheaper than normal commercial houses! Let them settle down in Hangzhou at a lower cost! The down payment ratio is only 30%, the company provides 0 interest installment repayment service, and all outstanding employees in the group who contribute to the outstanding performance are eligible to apply for the purchase of a house! ”

Wow~

Pu Weicai was stunned for a moment.

Mr. Wei's stroke is too big!

Take a 100-square-meter house as an example, the average price does not exceed 15,000, that is, the total price does not exceed 1.5 million.

The down payment of 30% is only 450,000.

The company accepts 0 interest installments, assuming that the installment is 20 years, and the loan is only 4375 yuan per month.

In addition, with the average salary of more than 24,000 yuan (excluding all kinds of bonuses) of the black hole lithography machine company, the pressure of repaying the loan is simply easy, which is equivalent to no pressure.

If you buy it according to the normal commercial housing price of 38,000 per square meter, the down payment alone will be more than one million, counting the bank interest, the average monthly loan repayment is 10,006, even if the monthly income reaches 20,000 or 30,000, it will still be overwhelmed by the mortgage, and the quality of life will seriously decline.

In other words, such a house slave life is not a human life at all.

Pu Weicai, who has had this kind of life experience for several years, still can't forget the feeling of depression and embarrassment, calculating, breaking a penny in half and spending it, and one year even considering that the cost of favors is too high, he gave up the plan to go back to his hometown for the New Year.

Now hearing Wei Ming say this, painful memories came to mind, and his nose was sore, and he almost burst into tears.

"Mr. Wei, I wish I could meet a boss like you a few years earlier."

Pu Weicai sighed and said: "With the average price of the house you set and 0 interest to repay the loan, I estimate that only more than 5,000 employees of the Black Hole Lithography Machine Company can afford it, and they will have to buy it if they borrow hundreds of thousands of loan sharks!" All of them, including senior executives, will apply to buy a home! ”

"As soon as this news is announced, the morale of the entire group will definitely explode and burst!"
