Chapter 527 Difficult Chip Breakthrough

    ?Use the copper clad laminate to print the circuit diagram on the copper clad laminate with a printing machine, then use an engraving machine to engrave according to the printed circuit diagram, and finally solder the relevant electronic components.

    Similarly, the same is true for chips.

    The role of a lithography machine is similar to that of a printing press.

    It's just that the size of the chip is too small and requires special printing.

    The specific method is to cover a layer of photoresist on the metal and then use light to erode the photoresist according to a certain circuit diagram.

    Light can corrode photoresist, but not metal, so a layer of "circuit diagram" is covered on the wafer.

    So how can we get the circuit diagram on the photoresist?

    The shape of the circuit is initially drawn on a relatively large reticle, and then the pattern of the circuit is reduced to a small size through the lens, and then irradiated on the metal plate coated with photoresist.

    The machine used in this process is a lithography machine.

    The complexity of the instrument is far beyond that of people. Now the most advanced lithography machine manufacturer in the world is ASML in the Netherlands. It can be said that this is the only relatively mature lithography machine company in the world.

    Because ASML occupies more than 80% of the global market share.

    The rest of the market share basically belongs to Toyo. Toyo's Nikon and Canon are not pure camera companies, but have quite impressive IC technology, including lithography machine technology.

    Of course, low-end lithography machine manufacturers include some South Korean brands.

    Therefore, larger chip production companies must find ASML.

    Moreover, the price of the other party's lithography machines is not cheap, basically ranging from tens of millions of meters to more than 100 million meters, and there is no bargaining.

    Of course, the technology of asml company is not developed by a certain technology team in the Netherlands, or developed by the Netherlands, but by the technical cooperation of the United States, the Netherlands, Germany and other countries, and the accessories of the products are also distributed in these countries.

    Therefore, the shareholders behind ASML include Capital International, BlackRock Group, Intel, Mountain Star, TIMC, etc. Most of the capital comes from the United States.

    Therefore, in this case, advanced lithography machines will not be sold to Xiaguo technology companies.

    Xiaxin International can purchase lithography machines through some contacts in the team, but most of them are second- and third-line products that have been eliminated.

    After the wafer is covered with a circuit diagram by the lithography machine, it enters the etching machine link.

    The etching machine is to use chemicals to erode the places that are not covered with photoresist, so that the surface of the crystal can become the shape we want, and the chip is made step by step in this way.

    This process corresponds to the etching machine, and the technical difficulty is much smaller than that of the lithography machine.

    After the establishment of Xiawei Semiconductor, because of the excellent technology of Yinshen's team, the company quickly became a top global company.

    Chen Xiao felt that he could handle Xiaxin International and Xiawei Semiconductor.

    The production of mobile phone chips is not a big problem, but the size and power consumption of the chips may be far behind the popular Nokia and Motorola on the market.

    In fact, 2004 was the best year for Xiaxin International.

    This year, Xiaxin International has been able to mass-produce 110nm chips, while the tire electromechanical at this time is 90nm, and there is actually only a one-year technological gap between the two.

    However, it is because of the rapid development of Xiaxin International that TIMC and the American capital behind it are very nervous, and immediately launched an attack on Xiaxin International.

    The best weapon is, of course, the infringement of intellectual property rights.

    The founder and boss of Xiaxin International is Zhang Jing, a patriotic person who used to work for Taiji Electric, and the senior team also came from Taiji Electric.

    This is beyond words.

    Everyone knows the following plot. Xiaxin International lost the lawsuit and lost 200 million US dollars in cash and 10% equity of Tire Electromechanical. Zhang Jing left Xiaxin International.

    Later, Xiaxin International's high-level leaders were in turmoil and had no intention of scientific research.

    When it stabilized, the United States also realized the importance of high-end technology products such as chips, and blocked high-end equipment for chip production and research and development.

    It was too late for Xiaxin International to react.

    Xiaxin International's chip production technology and international level are also getting better and better.

    It was also for this reason that Chen Xiao was not willing to cooperate with FTMC.

    The purpose of doing business with mainlanders is to make money, not to help you develop.

    Xiaxin International is a living example.

    If it helps you develop, how can you make money yourself?

    If you can kill you while making money, then of course I am happy to help.

      But the best moment in the history of Xiaxin International in 2004 was also the best moment for Xiawei Semiconductor. It is absolutely no problem to find them to make chips.

    If Changtian Technology can produce a mobile phone chip, even if this type of chip is a bit spicy, but it can be used and can meet the needs of consumers, then Chen Xiao can gain influence.

    And Chen Xiao believes that relying on the current level of his own integrated circuit lv12, it should be able to help these two companies.

    Chen Xiao said to Wang Yu: "Let's give birth."

    "You immediately prepare the relevant production data of Pangu chips, and we will be listed in Shanghai in a week."

    Wang Yu didn't know what the boss's purpose was, and he also knew that Changtian Technology didn't have any equipment for chip production.

    But as a subordinate, as the team leader of the chip laboratory, Wang Yu chose to follow the boss's order.

    After talking with Wang Yu, Chen Xiao had a good breakfast.

    The headquarters of Changtian Technology hired a special cook last year, not to mention the taste is quite good.

    After the meal, Chen Xiao returned to the office and together with Song Yi, prepared for the key work that needed to be done when going to the Shanghai stock market this time.

    ?Wang Xiang and Li Liang, vice president of Huawei, attended the test ceremony of the 3G network of Mozi Communication Company in Jiangzhou.

    In the case that mobile, telecommunications and other companies have not yet reached an agreement on the distribution of benefits in domestic 3G application rules.

    The country also felt that it could not wait any longer.

    Therefore, the same Changtian Technology used the 3G network for testing in Jiangzhou.

    This time the test did not participate in the company of Mobile Telecom Unicom, and it was independently operated by Mozi Communication, a subsidiary of Changtian Technology.

    All 3g base stations are built by Huawei. Because it is a test, Changtian Technology does not target all Jiangzhou users, but mainly targets the student user group in Jiangzhou University Town.

    The student user group accepts new things faster and is willing to cooperate with Changtian Technology in data collection, so it is a good test sample.

    Mozi Communications directly opened the communication company next door to China Mobile and China Unicom, and announced to the public that the 3G users who were tested would get a mobile phone card for free, and they would get a package of 50m traffic, 300 minutes of calls and 100 text messages every month.
