Compared with the information of the lithography machine, Liu Si found more literature on the ion etching machine. Because www.biquge.info lithography machine is still striving for a breakthrough at the 45 nanometer node, the domestic ion etching machine has broken through the 28 nanometer technology node.

According to history, China's semiconductor industry developed late, and it was not launched until the Tenth Five-Year Plan in 2001, so there is a "20-year gap" between China's high-end integrated circuit equipment and the international technical level. Now, Liu Si wants to establish a prototype of the whole industry chain of "design + silicon wafer + manufacturing + packaging and testing + carrier board" by establishing a domestic semiconductor industry chain as soon as possible.

The development of semiconductors mainly depends on the manufacturing process, and the trend of the manufacturing process is to develop in the direction of higher density, and the higher the density of the IC circuit design, which means that in the same size and area of the IC, there can be a higher density and more complex circuit design. The development and progress of microelectronics technology mainly depends on the continuous improvement of process technology. Since 1995, the chip manufacturing process has developed from 0.5 microns, 0.35 microns, 0.25 microns, 0.18 microns, 0.15 microns, 0.13 microns, 90 nanometers, 80 nanometers, and 65 nanometers, and has been developed to the latest 45 nanometers, 32 nanometers, 28 nanometers, 15 nanometers, 10 nanometers, and 5 nanometers.

China's breakthrough in the 28nm etching machine has made part of the research and development data of the 45nm and 32nm etching machine disclosed to a certain extent, which is exciting news.

With the breakthrough of lithography machine and etching machine, Liu Si was able to find a large number of nano-level data and literature. However, there is one of the most critical core equipment for semiconductor manufacturing equipment, that is, chemical precipitation equipment.

Chemical precipitation equipment, also known as thin film deposition equipment, has only broken through the two core equipment of physical vapor deposition (PVD) and chemical vapor deposition (CVD) in this regard, as well as other plasma-enhanced chemical equipment, high-density plasma deposition equipment, electrochemical gas deposition equipment, electron capture detector and so on.

The high-end technology of chemical deposition equipment has always been in the hands of the Americans, which is depressing, and Germany, the Netherlands, and Japan do not have this kind of technology, so Liu Si did not find much information in this regard.

I don't know if I don't search, and I'm shocked when I check it. The whole process of manufacturing chips has about 400~500 processes, and there are at least a dozen kinds of key equipment that need to be used. Without a strong integrated circuit equipment manufacturing industry that has mastered the core technology, it is impossible to talk about an independent and controllable integrated circuit industry.

Thinking of the situation that China is basically in a blank state, Liu Si is finally going crazy, he really doubts that he has invested a lot of money in semiconductor research and development, and will there be some results in the end?

In order to make China's integrated circuit industry bigger and stronger, we must develop China's integrated circuit equipment manufacturing industry. But here Liu Si only smiled bitterly, the entire domestic semiconductor industry is blank, and it is completely dependent on its own efforts. The gap between China's integrated circuit equipment industry and the international advanced level is basically like a ravine, which is promising.

Integrated circuit equipment manufacturing is a very sophisticated, complex and highly competitive industry. First of all, the speed of replacement is fast. Moore's Law 18 months to upgrade a generation, determines the frequency of equipment replacement. If companies can't keep up with this pace, the result is obsolescence. Secondly, the machining accuracy is extremely high. The nano-level machining accuracy has reached one millionth of a millimeter, a piece of equipment has reached more than 3,000 pieces of materials, and the software code has reached more than 1 million lines, requiring more than 200 suppliers. The development of a device is a large and complex system engineering. Finally, the validation cycle is long. The successful development of a piece of equipment is not only to complete the on-line verification, but more importantly, to pass the strict long-term test of the large production line, the whole cycle needs at least 18 months, and at the same time to meet the strict reliability and consistency requirements.

In addition to integrated circuit equipment manufacturing technology, Liu Si also has to invest in scientific research and development to expand the application field of products. For example, semiconductor lighting (LED), microelectromechanical systems (MEMS), advanced packaging, optical communication devices, compound semiconductors and other fields.

For the R&D investment in the semiconductor industry, it is necessary to wait at least until after 1998, and only after 98 years can he have the funds to invest in R&D.

At present, he needs to consider the development ideas of Vivo Technology Co., Ltd. and Meizu Electronics Co., Ltd. in China. Meizu Electronics is basically in a state of no development, only until January 98, and at the latest it needs to wait until October 1997, after Liu Si made a profit in the Hong Kong stock market.

Meizu Electronics has invested in research not only semiconductors, but also the development and research of DSP technology, sound cards, graphics cards, DRAM and other related technologies, which can be described as very difficult.

In fact, even in the middle of the Institute of Microelectronics of the Chinese Academy of Sciences, it was believed that it was also overseas Chinese and international students, so the key to the establishment of the Meizu Electronics Laboratory was overseas. In this regard, the cost is really not half a bit.

Now vivo technology Co., Ltd. and Meizu Electronics Co., Ltd. have begun to enter research and development this year, and it may be vivo technology Co., Ltd. that is on the right track.

In this way, the investment of 4.2 billion yuan is basically not used, in this regard, Liu Si has to prepare for construction, and use this fund to build the headquarters of vivo technology Co., Ltd. and Meizu Electronics Co., Ltd. The key is that the Shenzhen government has not yet approved the construction land for nearly 10 days, and he wants to give up the idea of investing in Shenzhen directly.

If it weren't for the prospect of Penguin and the upcoming Internet companies such as Ctrip, Sogou, Ganji, and Pacific, he would definitely leave Shenzhen and choose a new city to invest.

The technical R&D personnel and management team of vivo technology Co., Ltd. are still in CIIC, and for a while, the largest project invested by the Liu family in Shenzhen could not be on the right track, and Liu Si had no choice but to set his sights on the Internet industry.

Of course, for the QQ being developed by Penguin, Liu Si also has some suggestions and ideas that he wants to communicate with Zhang Zhidong and others. For example, QQ's version design, login interface design, icon design, etc., he Liu Si can provide some advice.

But today he will not visit Penguin, tomorrow he will have time. Just stayed in the hotel, after Liu's father sorted out some luggage, they were going to eat and take a nap, and then play happily for a while today.

Although Liu Si finally rented a yacht and took Liu's father and a group of bodyguards to the sea for sightseeing, Liu Si's mind still devoted himself to his career from time to time. What annoys him the most is where the remaining more than 1 billion of the more than 4 billion funds that have entered the domestic exchange of more than 500 million US dollars will be invested? Of course, it's not that there are no good projects, but that there are too many projects to invest in!

There are four main projects: warehousing, ports, shipping, and shipbuilding.

China's rapid development and the increasing scale of exports have led to an increasing demand for ports, shipping, warehousing, and shipbuilding, so state-owned related enterprises will not be put on the shelves at all. The port, shipping, warehousing, and shipbuilding industries have to be invested by Liu Si himself, but only 1 billion yuan of capital cannot cover four industries at once.

Why Liu Si must set his sights on the port, shipping, warehousing, and shipbuilding industries. Mainly under the guise of the future price increase of raw materials, he wants to vigorously purchase raw materials before the price increase, for the company's development to save costs.

In the case of oil and iron ore, for example, the price of iron ore is now based on long-term negotiated prices, and before 2003, the agreed prices between the Japanese Iron and Steel Association and Australian and Brazilian ore companies were the same.

However, after China surpassed Japan to become the largest importer of iron ore, our National Iron and Steel Association, which was excited to think that it controlled the qualification of iron ore pricing, suffered Waterloo. The price soared from $20 per ton before '03 to nearly $200 in 2011.

There are political factors for this reason, but the old style in China is also one of the important reasons. You say go and negotiate! also exposed his bottom line to the other party, and announced in a high-profile manner how many tons he would take.

In fact, it's not just about iron ore, but also about soybeans, cotton, grains, and other grains.

In 2003, the vigorous development of the domestic soybean oil extraction industry prompted China to change from a soybean exporter to a soybean importer, with an annual import tonnage of more than 10 million tons. In the second half of 2004, nearly 20 major soybean enterprises in China went to the United States for "collective procurement". After receiving the information, coupled with the cooperation of the US Department of Agriculture, the monthly soybean supply and demand report was significantly adjusted to adjust the soybean inventory data to a low level in more than 20 years, citing weather impacts. As a result, CBOT soybean prices rose from a low of about 540 cents in August 2003 to about 1,060 cents in early April 2004, a new high in nearly 30 years. This increase is equivalent to a price increase in China from 2,300 yuan to 4,400 yuan per tonne.

Under the domination of panic, China's crushing companies have stepped up their procurement efforts. At the beginning of 2004, more than 8 million tons of soybeans were "snapped up" in the United States, equivalent to an average price of 4,300 yuan/ton.

But then, starting in April 2004, international soybean prices fell rapidly, falling by nearly 50 percent. Domestic soybean processing has changed from a profit to an industry-wide loss.

In the face of such a price difference, some domestic processing enterprises, especially private enterprises, have no choice but to take breach of contract and give up the purchase contract and deposit originally signed at a high price. The so-called "ship washing" incident.

In response, the U.S. has taken the following measures: some large international soybean suppliers have sued Chinese importers for breach of contracts, with claims estimated to be as high as about 6 billion yuan; International grain merchants boycotted Chinese private enterprises, and except for some Chinese companies in which they had a stake, they no longer offered quotations to other Chinese importers; These suppliers jointly revised the text of the soybean export contract to China, and the revised contract terms were more unfavorable to Chinese importers.

This purchase has caused a heavy blow to China's private soybean crushing enterprises, and a ship of soybeans has lost hundreds of millions of yuan (a ship of soybeans according to Panamax grade, the loading capacity is 50,000 tons to 80,000 tons, a ton of soybeans will lose 2,000 yuan, and a ship of soybeans will lose more than 100 million yuan). According to conservative estimates, this purchase has caused at least 15 billion losses to China's crushing industry!
