On the morning of September 17th, lithography equipment stocks opened higher and continued to strengthen. Among individual stocks, Novel Optics and Wavelength Optoelectronics both hit their daily limit, while Guolin Technology, Suzhou Weige, Maolai Optics, Xinlai Applied Materials, and Lanying Equipment led the gains. Reports indicate that two people familiar with the matter revealed that SMIC is testing a deep ultraviolet lithography machine manufactured by Shanghai startup Yuliangsheng. The machine being tested uses immersion technology, similar to that used by ASML. One person familiar with the matter stated that while initial results from SMIC's trials are encouraging, it is unclear if and when the machine will be ready for large-scale chip production.
