Chapter 1469 We are manufacturing photolithography machines

Previous page        Return to Catalog        Next page

    "So, since 2001, we have been committed to the research of chip-level atomic clock manufacturing and related processes. Thanks to China's strong advantages in mechanical manufacturing and precision micro-machining processes, we have just made some breakthroughs not long ago.  ¡­¡±

    After Zhuang Jianye finished talking about the research and development background of chip-level atomic clocks, he changed the topic and introduced the results achieved: "That is our ztm-dl-18 rubidium atomic clock. The specific parameters are 89 mm long and 76 mm wide.  , height 28 mm, volume 200 ml, weight 320 g"

    "Wait a minute, Comrade Zhuang Jianye, how accurate is this ZTM-DL-18 rubidium atomic clock?" Before Zhuang Jianye finished speaking, a headquarter leader asked impatiently.

    Zhuang Jianye responded with a smile: "We have also made breakthrough progress in this regard. Through testing, we learned that the timing accuracy of the ZTM-DL-18 rubidium atomic clock is controlled at a frequency stability of 3 parts per 10 billion, and the 24-hour drift rate is less than 100,000  2 parts per billion, exceeding the chip-level atomic clock developed in Europe. Together with our improved hydrogen atomic clock, we can achieve a navigation accuracy of about 1 meter. If the algorithm is optimized for system optimization and orbit integration, the ultimate accuracy will be achieved.  It can reach 1 decimeter.¡±

    As soon as these words came out, it was like throwing a huge stone into a calm pond, and it immediately caused great waves in the venue.

    There is no way the data given by Zhuang Jianye is too amazing. Not to mention other things, the volume and weight of the rubidium atomic clock are 320 grams, 200 ml, less than 90mm in length and width, less than 30mm in thickness, and less than the size of a palm.  , for this pair of satellites, which weigh hundreds of kilograms and weigh several tons, it is not a problem to install not only one, but ten or eight satellites.

    The benefit brought by the greatly reduced weight of the rubidium atomic clock is not to reduce the total structure of the satellite, but to make way for the saved space and load to communication components.

    For example, it can be equipped with a higher-power transmitter, for example, it can be equipped with more anti-interference equipment, and for example, the diversification of communication systems can be realized, etc.

    It can be said that there are many benefits.

    Of course, the key issue is that the ztm-dl-18 rubidium atomic clock not only greatly reduces the weight and volume, but also reaches an amazing level of accuracy.

    The timing accuracy is controlled at a frequency stability of 3 parts per 10 billion, and a 24-hour drift rate of less than 2 parts per 10 trillion.

    Compared with the timing accuracy developed by Switzerland, the frequency stability is controlled at 5 parts per 10 billion, and the 24-hour drift rate is less than 1 part per trillion, which is almost an order of magnitude higher.

    This can be known from the accuracy provided by the two. The ztm-dl-18 rubidium atomic clock that can provide an accuracy of about 1 meter has far surpassed the European products with an accuracy of only 10 meters. The tail lights of the cars cannot be seen.

    It¡¯s just that the Europeans are unique in the world in the field of hydrogen atomic clocks, and have excellent control over accuracy. As a backup, they can achieve an accuracy of 1 meter in conjunction with a new generation of chip-level atomic clocks.

    But even so, compared with the ztm-dl-18 rubidium atomic clock alone, which can provide an accuracy of 1 meter, the hydrogen atomic clock it is equipped with is completely a system backup, not to mention that it is inferior in terms of service life.  Advantage.

    You must know that everyone in the venue was lamenting just a moment ago that the domestic atomic clock was not up to par. How could it be possible to complete the strategic intention of the headquarters before April next year? When they were thinking about what to do with a frown, Zhuang Jianye came up with a  A ZTM-DL-18 rubidium atomic clock that is more advanced than the same model in Europe.

    The emotions of shock, surprise, and disbelief immediately filled the venue, and finally turned into something called suspicion, which was cast back on Zhuang Jianye with strange eyes.

    It¡¯s no wonder that everyone present viewed this matter in this way. China Tengfei¡¯s main business is aviation and aerospace. Although it occasionally involves the manufacturing of precision instruments, these are unimportant marginal products, and most of them are used to rush ducks to the shelves.  With a stable supply of goods, China Tengfei will not continue to struggle in this regard.

    After all, projects such as large transport aircraft, large regional airliners, and carrier-based aircraft in the aviation field; hypersonic gliding warheads in the aerospace field; the ztm-nb-6 solid launch vehicle rapid launch system; marine environment monitoring satellites, and relay satellites have already made China  Tengfei is so busy that he still has time to consider other directions?

    Of course, even if we take a step back, even if China Takeoff is thinking about this, it does not have enough experience. We must know that the equipment, technology, and manufacturing involved in chip-level things are different from the precision micro-micron equipment involved in traditional aerospace.  Processing is completely two different things.

    The precision micromachining of aerospace is as high as a few filaments, which can be measured by a fraction of a human hair.

    But this kind of precision is only the most basic entry level in chip-level products. You must know that the units in this field are nanometers.

    This is like a rough guy and a?My dear girl, let a rough man who is used to wielding a hammer pretend to imitate the little girl holding an embroidery needle to embroider. That picture is so beautiful it's so eye-catching!

    So it¡¯s not that everyone present doesn¡¯t want to believe what Zhuang Jianye said is true, but these people from the front line rationally tell them that China¡¯s entry into the chip-level manufacturing field is a paradox in itself.

    Zhuang Jianye was not a fool, so he could not see the suspicious looks of everyone present, so he explained with a smile: "Although China Ascendas itself does not involve manufacturing in the chip-level field, our layout of the upstream and downstream industries of chip-level manufacturing in recent years has  It has never stopped. For example, several companies affiliated to our Institute of Aerospace Optics specialize in the manufacturing of laser light sources for deep ultraviolet lithography machines; there are also several listed companies controlled by Ascendas Investment, which are involved in guidance platforms and supply systems.  The structure and processing capabilities in ultra-precision light source reflection are among the best in the world.

    What's more, we also control whnb Integrated Circuit Manufacturing Co., Ltd. (Group) Co., Ltd. and wznb Microelectronic Equipment Manufacturing Co., Ltd. (Group) Co., Ltd., two chip manufacturing and special equipment manufacturing entities. You must know that one of them is an OEM for European and American chip giants.  The world's fourth largest new product manufacturer; the other is the world's sixth largest chip-specific equipment manufacturer.

    Through our capital operation and rational layout over the years, China's take-off itself has nothing to do with chip-level manufacturing, but it can also be said that it has a very deep origin. We are not as advanced as China in the manufacturing and process development of chip-level rubidium atomic clocks.  What kind of special project team or department should be set up within Tengfei? It was done naturally by integrating the upstream and downstream industry chains that have participated in investment over the years, giving full play to the comparative advantages of these manufacturers, and improving the potential of the industry chain"

    After a pause, Zhuang Jianye unscrewed the mineral water in front of him, took two big sips, and then said proudly: "The idea is the same as the lithography machine. The domestic 193-nanometer deep ultraviolet lithography machine has been used in whnb Integrated Circuit Manufacturing Co., Ltd.  The (group) company has been applied and achieved good results, which was developed by China Tengfei through the integration of the industrial chain. Since we can even make photolithography machines, is it so difficult to make chip-level atomic clocks?"
