Rebirth 2004: I can make money by writing.

It takes too long to upgrade the writing system from level 8 to level 9.

It took three and a half years!

[Hint 1: Upgrade the writing system to level 9]

【提示2：写字功能LV9，每写1万字＝奖励50000元，一次性奖励自由属性点+9】

"Oh my god, I finally got an upgrade!"

Hao Qiang showed a happy smile on his face, shook hands and pumped his fists a few times, which was still quite exciting.

He previously had 1 free attribute point, and now has a total of 10 points.

He had already figured out how to add some.

Spend 3 free attribute points to raise your appearance to 22.

Thinking power increases from 26 to 27, and the minimum value of the four-dimensional attribute is at least 22.

Only after the conditions are met can Hao Qiang improve his thinking ability, consuming 5 free attribute points at once.

For a moment, he felt his brain feel warm, then cool, which lasted for several minutes.

My thinking ability seems to have improved a little, but I feel it has been substantially improved. I'll know after testing it later.

After adding points, 2 free attribute points remain and cannot be upgraded.

……

Hao Qiang glanced at the virtual screen and wanted to improve his thinking ability, but the minimum requirement for the four-dimensional attribute was 24!

The upper limit is stuck directly.

Hao Qiang plans to test 27's thinking ability.

When the thinking power is 26, you can multiply any three-digit number with another three-digit number and calculate the result in your head within four seconds.

Moreover, it can perform complex calculations and multi-dimensional thinking.

After a few minutes of testing,

Hao Qiang probably figured it out.

After the thinking power reaches 27, multiplying any three-digit number by another three-digit number will take faster time.

You can also multiply any three-digit number by any four-digit number and calculate the result mentally within five seconds.

In addition, multitasking, more complex calculations, bursts of creativity, and insights into the nature and laws of things.

It can be said that the ability has become even more abnormal.

"Thinking power of 26 is already the highest value in human history. My 27 points created history. It was just a small improvement, but I didn't expect it to be such a big improvement." Hao Qiang said inwardly.

After testing his thinking ability, Hao Qiang activated the level 8 technology store.

【Upgrading...】

[Based on the host's world and its own situation, evolve technology suitable for the host's development...]

【Upgrade completed! 】

[Technical field 1: New battery manufacturing technology and process]

[Technical field 2: Intelligent robot manufacturing technology and process]

[Technical Field 3: Software Technology]

[Technical Field 4: Semiconductor Manufacturing Technology and Process]

[Tip 1: You can choose 2 fields and 3 technologies in the Level 8 Technology Shop]

[Hint 2: After the technology is extracted, the relevant knowledge will be integrated into the host's mind]

……

Hao Qiang took a quick look at the updated technology store and was pleasantly surprised.

All four areas have the technology he wants.

In the technology field 1, he found that there were many new solid-state batteries in the technology store.

The theoretical energy density of lithium-sulfur batteries can reach over 500Wh/kg, far exceeding the company's mass-produced NCM811 battery pack (270Wh/kg).

There are also many solid-state batteries with energy densities exceeding 400Wh/kg.

Of course, with high energy density, the manufacturing cost will definitely be high.

Alternatively, some solid-state batteries are difficult to produce on a large scale due to raw material issues and cannot meet international market demand.

But no matter what, the cost of applying new energy vehicles is too high, but in some areas, it doesn’t matter if they are a little more expensive, such as aviation.

Unfortunately, Hao Qiang could only choose 3 technologies.

In technology area 2, low-intelligence robotics technology already exists.

However, this technology is highly dependent on chips.

Without chips, it’s all empty talk.

In technical field 3, there are many software that Hao Qiang needs, such as more advanced chip design EDA software, 3D design software, finite element analysis, etc.

Hao Qiang looked through the last technical area 4 and finally found what he needed.

"Phew, if not, the wafer factory would be in vain!"

Hao Qiang breathed a sigh of relief.

He looked through it carefully and found the three technologies he wanted most.

Semiconductor wafer manufacturing technology and process, lithography machine manufacturing and process, chip manufacturing and process.

There are many types of semiconductors, and Hao Qiang chose single crystal silicon formed by silicon dioxide.

This technology, including the manufacturing technology and process of the core equipment single crystal furnace, is at the world's top level.

Can pull single crystals of 12 inches or more!

Wafer purity: 99.9999999999% and above, that is, 11 nines and above.

As long as the equipment meets the requirements, you can even reach 12 nines or more.

Of course, the higher the purity, the higher the manufacturing cost.

Generally speaking, the integrated circuit industry has extremely high requirements for the product quality of semiconductor silicon wafers. The purity must reach 99.9999999% (9 nines) or above, and the most advanced technology needs to reach 99.999999999% (11 nines). The photovoltaic industry's demand for single-crystal silicon wafers is 99.9999% (6 nines), and the preparation difficulty is far less than that of semiconductor silicon wafers.

Don't underestimate a decimal point, it directly affects whether advanced chips can be manufactured.

By 2023, the world will not be able to mass-produce wafers with a purity of 12.9.

Therefore, single-crystal silicon wafers with a purity of less than 11 nines are sufficient to meet the demand for top chips in the next 20 years.

In addition to the manufacturing technology of single crystal furnaces, there is also the manufacturing technology of wafer supporting equipment such as arc furnaces, quartz crucibles, graphite heaters, filtering devices, water conveying equipment, slicers, thermal fields and other equipment.

However, it is not difficult to develop these supporting equipment. Even if Hao Qiang does not have the technology of the technology store, he can develop it with the help of company employees. It just takes a little longer.

But it would be best if we could integrate this type of technology.

Hao Qiang just glanced at the semiconductor wafer manufacturing technology and process, and then glanced at the manufacturing and process of the lithography machine.

In fact, chip manufacturing and technology also include the manufacturing and technology of photolithography machines, but the technical level is relatively low.

This is also different from the suspension system technology in the level 7 technical store, which includes the special suspension system and automobile vibration reduction technology.

So, Hao Qiang simply chose a single item.

There are many types of lithography machines for manufacturing chips, generally ASML's EUV lithography machine (Zhiguang).

The lithography machine he chose is called "EBL (electron beam) lithography machine", which directly bypasses the technical patent of EUV lithography machine.

It is the new track, and its technology will not be outdated in the next few decades.

The more I learn about it, the more shocked I am.
