The leading figure of LED equipment has regained Chinese citizenship, reducing holdings to cash out nearly 100 million yuan for tax purposes.

A semiconductor equipment leader with a market cap of 2 trillion has issued an important announcement.

Recently, AMEC announced that it has received the 'Letter of Intent to Reduce Holdings' issued by its Chairman and General Manager, Zhiyao Yin. As he has restored his Chinese citizenship from foreign nationality, in order to comply with relevant tax regulations , he plans to reduce holdings of no more than 290,000 shares, representing 0.046% of the company's total share capital.

据披露，截至公告发布日，尹志尧直接持有中微公司股份415.94万股，占公司总股本的0.664%，上述股份均为公司首次公开发行前持有的股份。本次减持计划自本公告披露之日起15个交易日后的3个月内，在符合法律法规规定的减持前提下，通过集中竞价等方式减持公司股份。

As of the closing on January 9, AMEC's stock price was reported at 336.68 yuan per share, with a total market capitalization of 210.8 billion yuan. Yin Zhiyao plans to reduce holdings with a market value of approximately 97.64 million yuan.

According to disclosures, in the past 12 months, Zhiyao Yin reduced his holdings of company shares by 170,000 shares via centralized bidding between May 27 and August 26, 2025, representing 0.027% of total share capital, with a price range of RMB 170.76 to RMB 207.36 per share.

Previously, AMEC's 2022 annual report showed that Zhiyao Yin held U.S. citizenship. In AMEC's 2024 annual report, Zhiyao Yin's nationality was changed to Chinese.

As a leader in China's semiconductor equipment industry, Yin Zhiyao's personal journey is deeply intertwined with the development of AMEC, highlighting the patriotism and industry responsibility of a generation of researchers.

Data shows that Yin Zhiyao was born in Beijing in 1944, entered the Department of Chemical Physics at the University of Science and Technology of China in 1962. After graduating in 1968, he successively worked at the Lanzhou Refinery and the Lanzhou Institute of Physical Chemistry, Chinese Academy of Sciences, accumulating a solid research foundation. From 1978 to 1980, he pursued his master's degree in the Department of Chemistry at Peking University, then went to the University of California, Los Angeles for further studies, where he earned a Ph.D. in Physical Chemistry, embarking on a deep dive into the semiconductor field.

From 1984 to 1986, he worked at Intel's Center for Technology Development as a Process Engineer; from 1986 to 1991, he was employed by Lam Research, serving successively as Senior Engineer and Senior Manager in the R&D Department; from 1991 to 2004, he worked at Applied Materials, holding positions including Chief Technology Officer of the Plasma Etch Equipment Product Headquarters, Vice President of the Corporation, General Manager of the Plasma Etch Business Group, and Chief Technology Officer of the Asia Headquarters.

It is reported that during his tenure at Applied Materials, Yin Zhiyao participated in and led the R&D of several generations of plasma etching machines internationally, obtained 86 US patents and over 200 international Patents, and was evaluated as "one of the most accomplished Chinese Americans in Silicon Valley".

It is reported that in 2004, 60-year-old Zhiyao Yin did not choose to retire but instead led a group of technical elites working in Silicon Valley to return to China and start a business. From 2004 to the present, Zhiyao Yin has served as Chairman, General Manager, and core technical personnel of AMEC. In 2024, his total pre-tax compensation from the company was 14.8514 million yuan.

Over the past decade, Yin Zhiyao led the team to continuously break through technical barriers, with frequent good news on the first national set of semiconductor equipment.

To date, AMEC can meet over 95% of etching demand nationwide; its etching equipment covers production processes from 65nm to 5nm, making it the first mainland supplier to enter TSMC's 5nm production line.

In the field of MOCVD equipment, AMEC has also become the largest MOCVD equipment supplier in the GaN-based LED market share.

AMEC latest disclosed Q3 report shows that in the first three quarters of 2025, the company maintained strong development momentum, achieving revenue of 8.063 billion yuan, a year-on-year increase of 46.40%; and net profit attributable to shareholders of listed companies of 1.211 billion yuan, a year-on-year increase of 32.66%.

公告同时明确，尹志尧并非公司控股股东、实际控制人及一致行动人，亦非直接持股5%以上股东。本次减持计划实施存在不确定性，其将根据市场情况、公司股价等因素决定是否实施及具体减持数量、价格。此次减持不会导致公司控制权发生变更，也不会对公司治理、持续性经营产生影响。

In addition, in December 2025, AMEC announced that it plans to acquire 64.69% equity of Hangzhou Zhonggui by issuing shares and paying cash.

这并不是中微近期第一次并购。实际自2019年上市以来，中微公司就频频对外投资，合计已经拿出超20亿元，投资约40家产业链上下游企业。
