After Huang Xiuyuan came to Shandong Province, he participated in part of the scientific research work at the headquarters through internal emails.

Lu Xuedong is here in the scientific research department, and at least he doesn't need to worry about many things.

In the same way, Lin Baijie and Huang Wei often stared at the company's operations. In fact, his work is mainly about major decisions.

I read the scientific research briefing sent by Lu Xuedong.

He rubbed the slightly emerging stubble and wrote down some suggestions from time to time, as well as related research and development directions.

At present, the technology tree of Suiren Company can be divided into several cores, namely the nanomaterial synthesis technology of the multilateral silicon oxide group, the recycling technology derived from six-cone ball oxygen, the organic polymer decomposition technology of nitrogen 16 molecules, and the silicon nanotechnology derived from silicon 9 molecules.

Among them, polylateral silicon oxide is the core of the core.

The large-scale production of various nanowires has promoted the development of nanowire semiconductor technology. If the chip accuracy level is not required, it will reach about 20 nanometers, Suiren Company will soon be able to come up with a chip production line.

Although the accuracy of nanowire textile machines can reach around 20 nanometers, the problem is that the production speed is too touching.

At the second-rate 40-nanometer level, industrial production can already be achieved, but Huang Xiuyuan did not agree to produce it because this level of chip is not enough to compete with Intel, Samsung, and TSMC.

You should know that the chip technology in developed countries has reached 40 nanometers in 2006 and will be increased to 32 nanometers next year. The commercial fin transistor was launched in 2011, the 22-nanometer process was launched in 2012, the 14-nanometer process was developed in 2014, and the 10-nanometer stage was entered in 2016.

Huang Xiuyuan looked at the R&D progress table. Currently, the 20-nanometer-level nanowire textile machine has 10 billion transistors, which takes about 138 to 167 days to weave.

This processing time is too long, and the speed must be increased to 10 billion transistors and completed within 50 days before initial mass production can be achieved.

However, Huang Xiuyuan has issued instructions that he can use the 40-nanometer process on a small scale to try to design some simple chips, such as electronic control chips, temperature control chips, etc. These industrial accessories chips with single functions can be produced using the 40-nanometer process, and there is no problem.

After all, at this stage, foreign high-end CPUs, GPUs, etc. are still using 40-nanometer processes. Most of the industrial chips such as electronic control chips use 64-80-nanometer processes.

Even if these chips cannot be marketed in a short period of time, they can be used for themselves. Anyway, there are many subsidiaries within Suiren Company. With the approaching era of intelligence, the demand for these professional industrial chips will also become increasingly large.

By using it internally, improving the chip design process at the same time, laying the foundation for the future.

After looking at the relevant progress of nanowire semiconductors, Huang Xiuyuan looked at the next project.

"Glass memory?" He was a little surprised. This was a researcher in the semiconductor laboratory who applied for a research and development project.

This researcher named Miao Guozhong designed a special glass memory. The core technology of this glass lies in the isomer in the silicon 9 molecule - isosilicon 9 molecule.

Different from the positive silicon 9 molecules that form silicon nanoplating, the heterosilicon 9 molecules themselves become silicon 6 molecules and three separate silicon atoms under ultraviolet laser irradiation.

As for the light reflection of heterosilicon 9 and silicon 6, the two are different. The heterosilicon 9 tends to reflect blue light, while the silicon 6 tends to reflect yellow light.

In this way, the different silicon 9 can be changed by laser to form two reflected light points to realize the engraving of information.

According to the experimental data of Miao Guozhong's team, they can currently achieve 86G data storage in the laboratory on an area of ​​1 square centimeter.

Since the composite is inside the glass, even if it is stored for thousands of years, data will not be lost. If silicon nano-plating is added, external forces will be difficult to destroy the glass memory.

The only disadvantage is that after burning data, the glass memory is basically unmodified, which means that the glass memory is one-time. When all storage points are burned, the data can no longer be stored.

Huang Xiuyuan looked through the detailed test data and found another problem, that is, the reading speed requires the coordination of the optical projector and the photosensitive decoder. Although it is faster than ordinary disks and tapes, it is slower than flash memory (U disk), and is between the two.

However, he saw the potential of glass discs, at least in cold backup, which can replace the current tape discs.

The so-called cold backup refers to data that needs to be stored for a long time, such as bank user information, official organization information storage, museum book content, information storage of large Internet companies, etc., or disaster backup.

All these areas require cold backups. To meet the storage conditions of cold backups, several characteristics must be met: one is the huge storage volume, the second is the long shelf life, and the third is the good stability.

Currently, tape disks are used to store information in these fields. Tape disks are the common audio tape disks that were previously common, and the two are the same technology.

For example, the time information database is equipped with two huge tape repositories, which are specially used for backup to ensure that all information is not lost.

Although the service life of tape disks is generally around 20 or 30 years, the longest can reach fifty years, which is one order of magnitude higher than the 3 to 5 years of disks.

However, the effective storage period of glass discs starts in a thousand years, because the degradation time of glass being buried underground may take about 1 million to 2 million years.

If the warehouse where glass discs can be stored can maintain constant temperature and humidity for a long time without being exposed to the external environment, it is estimated that the data points inside the glass disc can be maintained for tens of thousands of years.

If reversible reading and writing can be overcome, then glass discs can even replace mechanical hard disks and part of the semiconductor memory market.

According to the calculations of Miao Guozhong's team, the data points of the glass disc can be further improved at present, and the composite density of the data points can theoretically be increased to the limit of 0.5 nanometers.

In theory, 400 mega data points can be arranged for an area of ​​1 square centimeter. Each data point can be represented by yellow light and 1 by blue light.

Usually, in computers, 1 byte (B) is composed of 8 binary numbers, 1KB=1024B, 1MB=1024KB, 1GB=1024MB, 1TB=1024GB, these are our common data storage units.

400 megadata points, converted into GB, are 46,562,000 GB, or this is just the area of ​​the finger, and the data capacity that can be stored theoretically shows that its potential is very huge.

As long as you make the size of an ordinary optical disc, the storage volume is absolutely not small.

With long-term stable storage, Huang Xiuyuan doesn’t know whether it can replace semiconductor storage and flash memory, but replacing tape disks is a foregone conclusion.

He wrote an email specifically on this technology and sent it to Lu Xuedong, who was at the Lingnan headquarters, to increase support for Miao Guozhong's team and develop glass discs and supporting technologies.

After looking through other content, there were many valuable technical directions, Huang Xiuyuan issued instructions one by one.

His guidance will help the scientific research work of Suiren Company avoid detours, which is very important.

Sometimes in scientific research, direction is crucial. If you choose the wrong direction, you may go to a dead end.
