Chapter 432

After Lin Yi finished speaking, he went to Dr. Wen Xia's laboratory.

After completing the carbon fiber material, he was now researching the nanotechnology research that Lin Yi gave him.

Simply put, it was biological medical robots.

However, his research had also hit a bottleneck.

That was manufacturing and control; the manufacturing and control of nanorobots is a complex process.

Because the size is very small (usually on the nanometer scale), manufacturing nanorobots requires high-precision technology and equipment.

With the technology given by the system, it uses cutting-edge lithography technology.

At the very least, it also requires extreme ultraviolet lithography machines to continue the research.

Besides constructing nano-scale bodies, it also requires lithography of nano-scale energy collection and storage systems.

That is to say, the problem of lithography machines could not be delayed.

However, restricted by the Wassenaar Arrangement, let alone EUV extreme ultraviolet lithography machines, even deep ultraviolet lithography machines,

the only manufacturer in the world capable of producing high-end lithography machines, the Dutch ASML company, could not possibly sell them.

"System... how much money is needed to upgrade the lithography equipment to a 2020 extreme ultraviolet lithography machine?"

"Ding... calculating..."

Because it was not for manufacturing chips, Lin Yi didn't intend to get a set of chip production equipment,

he just needed lithography equipment.

After all, at this time, Lin Yi couldn't possibly know that the Long Guo's chip manufacturing would be sanctioned in the future.

Although the Long Guo couldn't import cutting-edge lithography machines now,

but, wafer foundries like TSMC were still very willing to foundry chips for the Long Guo.

For example, the Kirin 955 released by Huawei recently, the SoC logic chip was foundry-produced by TSMC.

So for the time being, Lin Yi still couldn't see any problems with chip foundry.

"Host can spend 2 billion US dollars to unlock lithography equipment!"

"2 billion US dollars, are lithography machines that expensive? What about 2010?"

"Ding... detected that in 2010, there were no extreme ultraviolet lithography machines on Blue Star, host cannot purchase!"

Hearing the system say this, Lin Yi checked on the internet and sure enough, extreme ultraviolet lithography machines were only produced last year, which was 2015,

used for manufacturing Apple and artificial intelligence chips.

"2 billion US dollars it is!"

Lin Yi came back from the laboratory, sat in his boss chair in his office, and sighed.

Then in an instant, he found that the 25.3 billion US dollars in his overseas account,

suddenly became 23.3 billion US dollars.

Although he earned quite a lot from his arms sales, his consumption was also terrifying.

For him, just upgrading one lithography machine cost 2 billion US dollars.

In reality, because of the cross-disciplinary nature, Lin Yi didn't know that the Dutch ASML company spent time and effort to research extreme ultraviolet lithography machines,

and it cost over 10 billion US dollars.

The system only charged Lin Yi 2 billion US dollars to unlock a 2020 product.

This price was already quite favorable.

After unlocking, looking at the 30 million US dollar per lithography machine,

Lin Yi spent another 300 million to buy 10 units.

He believed these lithography machines should be enough for the laboratory to use!

As a result, he only learned later that to use lithography machines, one also had to build a clean room of at least level 10,000.

Consequently, without anyone in the Long Guo noticing, Fengyi Tech actually started building a chip-level clean room.
