Yunnan Germanium Industry Stock Trading Abnormal Fluctuation Announcement, the company's controlling subsidiary Yunnan Xinyao Semiconductor Materials Co., Ltd. main business is the production and sales of indium phosphide chips and gallium arsenide chips. Similar to other semiconductor materials, III-V compound semiconductor substrates, including gallium arsenide and indium phosphide chips, also need to constantly evolve to larger sizes. Currently, the actual size specifications of indium phosphide chips used by downstream customers worldwide are 2-4 inches, with 2-inch and 3-inch being the main sizes in China. Whether we can smoothly evolve towards larger size specifications in the future, in addition to breakthroughs in technology at all levels of the industry chain, is also influenced by factors such as process reliability, cost and capacity, policy and market, and there is uncertainty.
