➀ The manufacturing industry and technology are crucial for China's future development;

➁ In the manufacturing sector, excess profits are earned through high-margin products;

➂ In the technology sector, high profits are used to support wafer fabs and photolithography machines;

➃ How to create a positive feedback loop? For every million-dollar luxury car sold by Huawei, it equals one less luxury car sold in developed countries like Europe and the US, and high-level engineer positions shift from Europe, the US, and Japan to China; Huawei (high-tech) and its high-margin manufacturing sector are the directions for this bull market.

➀ The smallest wafer factory showcased at CEATEC 2024 demonstrates the use of ultra-small semiconductor manufacturing equipment in photolithography processes.

➁ These small wafer factory manufacturing equipment can use home power supplies outside of cleanrooms.

➂ The capital investment for the smallest wafer factory is only about 500 million yen, making it accessible for small and medium-sized enterprises and startups.

➃ The equipment can be manufactured in single pieces, allowing for easy small-batch production of various products.

➄ The minimal wafer factory's manufacturing equipment has the advantage of low power consumption and can use home AC100V power.

➅ The organization behind Minimal Fab aims to revolutionize semiconductor manufacturing with its innovative approach to multi-product, small-batch production.

➆ Minimal Fab's technology has the potential to significantly reduce capital investment and manufacturing cycles, making it suitable for IoT applications.

➀ The research on hollow-core fibers is active but not yet widely commercialized due to various reasons, such as incomplete theoretical exploration and immature mass production processes.

➁ Y10T283 employs three segments of hollow-core fibers spliced together for academic research.

➂ This year, Changfly manufactured 15km long continuous hollow-core fibers and discussed the impact on performance in large-scale production.

➃ The wall thickness of the tube for low-loss bands exhibits certain characteristic thicknesses to achieve low-loss design goals.

➄ Thinner wall thickness results in longer resonance wavelength spacing, wider low-loss bands, but also more sensitive pressure differences.

➅ Changfly evaluated the tolerance of the inner and outer diameter ratio and pressure difference based on a balance between manufacturing difficulty and performance.

➆ Changfly selected a low-loss window with a wall thickness of 1.1μm, achieving a minimum loss of 0.25dB/km for 10km hollow-core fibers and about 0.58dB/km for 15km fibers.
