# New breakthroughs in photoresist, multiple photoresist concept stocks have been significantly bought by financing clients

According to Science and Technology Daily, recently, Professor Peng Hailin's team from the School of Chemistry and Molecular Engineering at Peking University, along with collaborators, used cryo-electron tomography technology to analyze for the first time the microscopic three-dimensional structure, interfacial distribution, and entanglement behavior of photoresist molecules in a liquid phase environment in situ, guiding the development of an industrialization plan that can significantly reduce photolithography defects. The related paper was recently published in Nature Communications. From the performance data for the first three quarters of 2025 that has been released, according to Data Treasure statistics, based on the third quarterly report, performance express report, and the lower limit of the forecasted net profit, 11 photoresist concept stocks showed a year-on-year increase in net profit for the first three quarters, including Jingrui Electric Materials, Jiuri, Ruilian New Materials, Aisen Co., Ltd., and DING LONG. In terms of funding, according to Data Treasure statistics, as of October 23, there are 5 photoresist concept stocks that have received a net financing purchase of over 100 million yuan since October, namely Yake Technology, Xinlai Yingcai, Shengquan Group, Huamao Technology, and Hubei Yihua
