The development of chips requires a process.

The first step is to prepare semiconductor-grade silicon ingots.

In this era, 8-inch (200mm) diameter wafers are generally used, and major mainstream manufacturers are working on related technologies with larger diameters of 12-inch.

At the Institute of Semiconductor Materials, the researchers are nervously watching the data displayed in the instrument.

Wang Anran also felt the solemn atmosphere. Semiconductor wafer research is one of the first major projects to cooperate with Huaxin Technology with the Academy of Sciences.

The 6-inch (150mm) diameter wafer stretching currently is being carried out, and the technology used is also the most mature CZ straight-pull method in the world.

"heating!"

"The current temperature of the crucible furnace is 1350 degrees."

“Place seed crystals, 3, 2, 1, start.”

"touch!"

With Qian Junjie's order, the seed crystals fixed on the rotating chuck rotated slowly at the designed speed.

In the crucible furnace, with the increase of the seed crystal, the single crystal silicon at the bottom begins to grow.

The data can be found through the stress sensor installed on the chuck.

For evenly growing silicon ingots, the stress should continue to increase, and the display on the monitor should be a linear line.

This straight line is within the allowable range and can be preliminarily determined that the single crystal grows evenly. However, to confirm the quality of the silicon ingot, a series of complex tests are still required, but now it is stuck in the first step.

Just when the people participating in the test did not dare to make a sound, a red light suddenly flashed on the alarm.

"Quick, stop improving!"

The operator quickly pressed the control button and the lifting of the chuck stopped immediately.

However, it was obviously too late. Qian Junjie looked at the monitor and the stressed line head suddenly fell down, indicating that the growth of single crystal silicon had broken and the experiment failed.

Qian Junjie shook his head and said to a staff member in his thirties and forties beside him: "Cleaning the crucible and preparing for experimental data analysis."

After arranging the matter after the improvement, Qian Junjie walked to Wang Anran and said, "Mr. Wang, I'm sorry, I failed again. If you are interested, please go to the conference room and I will report to you in person."

In fact, Qian Junjie doesn't like dealing with businessmen, but he has no choice but to Wang Anran. He has invested eight million yuan in the Semiconductor Materials Research Institute. No matter what, he has to give him an explanation.

Qian Junjie still understands this kind of human nature.

When Wang Anran saw the old scientist Professor Qian, who was graceful, he called himself Mr. Wang seriously and wanted to report his work to him, so he was too embarrassed to know what was going on.

"Professor Qian, just call me Anran. I am a student led by Professor Lu Wei and I came here to study."

Qian Junjie is not unfamiliar with Lu Wei. In fact, the circle of scientists is very narrow. Qian Junjie usually doesn’t live in the laboratory, so he is in the library. If neither place is present, he will definitely be sleeping.

I am familiar with Lu Wei, so naturally I am in the same industry and have some contacts.

"Has Lu Wei become the dean now?"

Wang Anran's face was stunned and shook his head.

"I heard that Lu Wei is now rich. Someone donated 20 million yuan to do research for him. Damn it, it's really lucky."

Wang Anran was a little surprised, and the respected seniors would swear.

"You won't donate it!"

“…”

In the conference room, Professor Qian held a stack of test materials.

"An Ran, you have also seen that the experiment just now failed."

"Professor Qian, I am also a science and engineering student. I know that there are no failures in the experiment. At least we are not without gains. If we try more, we will always find the right method."

Qian Junjie shook his head and said, "Mr. Wang, it's not that I'm crying poor. Such an experiment cannot be carried out several times. This time, even the allowances of our staff were paid, and there was no money."

When Wang Anran heard this, he was amused. Professor Qian had to bow his head in front of the money. He was thinking about investing money by himself? No problem.

"Professor Qian, how much does it cost to have such an experiment?"

Qian Junjie handed over a list and said to Wang Anran: "The main thing is the material cost. You have seen just now that the seed crystals used for lifting are made of special chemical vapor phase methods. Our country cannot produce them yet. They are all imported from Japan. This piece of seed crystal costs 600,000 yuan. With some chemical consumables, the entire test process costs more than 800,000 yuan."

For China in this era, 800,000 is not a small amount.

This is still the production of 6-inch silicon ingots that were eliminated by others.

Professor Qian said again: "Mr. Wang, you have also seen that this is just a tensile test. Orientation and appropriate amount of n-type or p-type doping have not been carried out. Although our scientific researchers have done a lot of preliminary work, it is estimated that such tests will be carried out at least one hundred times."

Wang Anran frowned slightly. More than a hundred times, it was only more than 80 million. There was no problem with paying the money himself, but there must be an explanation for this money.

"What do you want to say?"

"Huaxin Technology requires 60% of the rights and interests of intellectual property rights, and the remaining 40% are allocated by the Academy of Sciences and the research team."

"I can't make the decision, but I think the Academy of Sciences should agree..."

For Wang Anran, the six-inch wafer technology is also a useless existence. Most of the foreign countries have been eliminated. Now it is an eight-inch world. In a few years, Intel will fully switch to the production of 12-inch wafers.

It should be noted that the larger the diameter of the wafer, the more chips can be integrated on the same wafer, the lower the production cost. This is the trend.

The current situation in China is that scientific research institutions generally lack funds, so research on corresponding basic subjects naturally cannot keep up. What Huaxin Technology needs to do is to build a bridge between enterprises and research institutions, and the integration of production and research is also the future direction.

"An Ran, this 80 million is not going to have to invest so much at once. Maybe you can succeed in fifty times!"

Wang Anran said: "Professor Qian, you must also do research not only for 6 inches, 8 inches and 12 inches. You report your budget to me and I will personally approve it."

After returning to the company, Wang Anran carefully listed a table, including 14 types, including wafer production, doping, semiconductor materials, high-purity acid and alkali solvents, thin film processes, wafer processing, pollution control, baking and etching, metal precipitation, ion implantation, and more than 80 research topics.

Among them, it is either funded research, cooperative development, or led by Huaxin Technology, seeking technical cooperation in universities or research institutions.

Looking at the densely packed notes on the paper, Wang Anran muttered to himself.

"Eighty topics, even if one-tenth of them are successful, can help the development of the country's semiconductor industry."

One of the reasons why the semiconductor industry in the United States is that it has a very mature semiconductor research and development environment in the United States.

In China, it is extremely difficult to buy a chip to study.

This is the difference.

Huaxin Technology’s unique success cannot change the current situation of the country. Wang Anran believes that while adding more efforts to basic research, it is also time to establish a semiconductor enterprise incubation base.
