氧化镓产业化提速 + 国产替代共振，半导体材料 ETF (562590)开启回调蓄势

Core Viewpoint - The semiconductor materials sector is experiencing increased market attention due to the intensifying competition in the rare earth field between China and the U.S., with a notable shift towards the development of fourth-generation semiconductor materials, particularly gallium oxide, which is gaining industry recognition and moving towards industrialization [1][2]. Group 1: Market Performance - As of June 17, 2025, the CSI Semiconductor Materials and Equipment Theme Index (931743) decreased by 0.50%, with mixed performance among constituent stocks [1]. - Leading stocks included ShenGong Co. (+3.88%), Zhongjing Technology (+1.75%), and Kangqiang Electronics (+1.46%), while the biggest decliners were Anji Technology (-2.73%), Huafeng Measurement Control (-2.45%), and Zhongke Feimiao (-2.02%) [1]. - The Semiconductor Materials ETF (562590) fell by 0.67%, with the latest price at 1.03 yuan [1]. Group 2: Industry Trends - The semiconductor materials sector is closely tied to the capacity utilization rates of wafer fabs, with domestic demand for domestic alternatives driving growth [2]. - The ongoing development of third-generation semiconductor materials is transitioning to fourth-generation materials, with gallium oxide recognized for its advantages in voltage, current, power, and loss [1]. - The Ministry of Science and Technology of China has included gallium oxide in the "14th Five-Year Plan" for key research and development, indicating a clear intent to advance fourth-generation semiconductor materials and catch up with international standards [1]. Group 3: Investment Opportunities - According to Huatai Securities, the semiconductor equipment market is expected to present three main investment opportunities in the second half of the year: 1. Increased demand for advanced process logic and advanced packaging driven by generative AI 2. Structural opportunities from the expansion of advanced processes 3. Investment opportunities arising from the shift of market share from the West to the East in China [2]. - The Semiconductor Materials ETF (562590) closely tracks the CSI Semiconductor Materials and Equipment Theme Index, which includes 40 listed companies deeply involved in the semiconductor materials and equipment sectors, reflecting the overall performance of these companies [2].
