Good news for China litho industry

Feilihua achieves small batch production of ultra-low expansion quartz glass​


Hubei Government Service Network announced the filing of the ultra-low expansion quartz glass research and development and production project of Hubei Feilihua Quartz Glass Co., Ltd. The ultra-low expansion quartz glass R&D and production project of Hubei Feilihua Quartz Glass Co., Ltd. is located in Jingzhou Economic and Technological Development Zone, Hubei Province.

According to the filing information, the project uses existing plant buildings and equipment to carry out intelligent upgrades and renovations on the furnace structure, lifting equipment control system, exhaust system, etc.; adds gas cabinets, material cabinets, evaporators, purification equipment and related detection devices, develops ultra-low expansion quartz glass for the demand for quartz glass materials for extreme ultraviolet (EUV) lithography machines, and builds a pilot production line .

According to China Powder Network, compared with other low-expansion quartz glass, SiO2 - TiO2 quartz glass has a lower thermal expansion coefficient, and can even achieve zero expansion or negative expansion within a certain temperature range. Therefore, titanium-doped quartz glass is also called ultra-low expansion quartz glass .
The preparation methods of low-expansion quartz glass mainly include chemical vapor deposition, indirect synthesis and sol-gel methods. It has an extremely low thermal expansion coefficient and is a key material in high-tech fields such as optical components for semiconductor lithography equipment, astronomical telescope reflectors, and atomic clock cavities

In March this year, the State Intellectual Property Office announced a patent entitled "A production method and production device for low expansion coefficient quartz glass ingots",
and the applicant was Hubei Feilihua Quartz Glass Co., Ltd. The invention relates to a method and device for producing a low expansion coefficient quartz glass ingot, and belongs to the technical field of low expansion coefficient quartz glass production. The invention uses concentrated hydrochloric acid as solvent and SiCl 4 and TiCl 4 as solutes to prepare a mixed raw material solution; due to the potential solvation effect, silicon atoms and doping atoms are uniformly dispersed in the mixed raw material solution in an ionic state. This solves the problem that the existing preparation process is difficult to accurately control the titanium content and cannot maintain its consistency during the production process, resulting in fluctuations in the distribution of doping elements in the quartz block, which aggravates the instability of the performance of the quartz material. The invention can reduce the fluctuation range of the doping material by 67%; the fluctuation range of the thermal expansion coefficient is reduced by 31%; it has positive significance for the preparation of low expansion coefficient quartz glass ingots.

The report mentioned that Shanghai Light Source (SSRF) has built a dedicated beamline for EUV lithography mask inspection. SSRF is able to generate stable and pure 13.5nm EUV light for detecting and reviewing defects in EUV lithography masks. It achieves high numerical aperture (NA) and high resolution by using Fourier synthesis illumination and off-axis plane imaging technology. Dark field scattering mode is used to achieve high-sensitivity detection of mask defects. The design goal of this beamline is to achieve a mask imaging resolution of 30nm and a detection sensitivity of 30nm. The inspection mode and review mode are integrated in a compact cavity, and the two modes can be easily switched. The beamline is currently being debugged and is expected to be completed this year.

Looks like there is also another EUV facility , they plan to reach 12nm half pitch next year.

"Hefei Light Source - Low-energy Synchrotron Radiation Facility for Extreme Ultraviolet Lithography Research".

The Hefei Light Source (HLS) is built and operated by the National Synchrotron Radiation Laboratory (NSRL) of the University of Science and Technology of China. It is China's first dedicated synchrotron radiation facility and the only light source currently optimized in the vacuum ultraviolet (VUV) to soft X-ray region. HLS is equipped with an 800 MeV electron storage ring, 11 beamlines and 14 experimental stations.
Four of the beamlines can provide high-brightness and narrow-bandwidth extreme ultraviolet light in the 13.5nm wavelength range. HLS is equipped with experimental technologies such as EUV metrology, interferometric lithography, coherent diffraction imaging, and resonant soft X-ray scattering, which can support applied basic research and technology development in the field of EUV lithography. NSRL also plans to further improve the brightness and coherence of EUV light by increasing the electron beam current to more than 500 mA and reducing the electron beam emittance to less than 10 nm·rad. As the plan progresses, HLS will soon be converted into a dedicated EUV synchrotron radiation light source. In this report, the current status of Hefei Light Source and its experimental technology are introduced.
