# A-share photolithography machines and photoresist concept stocks lead the opening gains

Red Avenue New Materials hit the daily limit, Aisen Co., Ltd. and CCEM rose over 10%, while NATA OPTO-ELECT, Shanghai Xinyang, and several other stocks opened high. In terms of news, recently, Professor Peng Hailin's team from Peking University's School of Chemistry and Molecular Engineering, along with collaborators, used cryo-electron tomography technology to first analyze the microscopic three-dimensional structure, interfacial distribution, and entanglement behavior of photoresist molecules in situ in a liquid phase environment, guiding the development of an industrialization plan that can significantly reduce photolithography defects
