The Crystal Magnesium Mask Project focuses on the research and production of high-end masks (mask plates) for process nodes of 28nm and above. The project plans a total investment of 12 billion yuan and will be constructed in two phases: the first phase will invest approximately 6.5 billion yuan, and the second phase will invest approximately 5.5 billion yuan. The structure that was capped off this time is the production line workshop of the first phase. After the project is completed, it will achieve a breakthrough in "Hefei production" of high-end masks, strengthening the key link of the semiconductor industry chain. 

It is known that the photomask is a key component in the semiconductor manufacturing process, and its quality directly affects the yield and performance of the chips. From the global market landscape, the semiconductor photomask sector presents a dual-track model of "in-house production + third-party supply". Due to the complexity of the advanced process wafer manufacturing technology below 28nm, the supporting mask plates involved in the important process secrets of the wafer manufacturing plants, most of the mask plates used by advanced process wafer plants are produced by their own internal factories. For mask plates used in more mature processes such as 28nm and above, chip manufacturing companies, in order to reduce costs, tend to purchase from independent third-party mask plate manufacturers while meeting technical requirements.

Since the project started construction, the construction management team of Hefei Lanke has always adhered to the construction concept of "high standards, high quality empowerment, and high efficiency promotion", strictly following the construction norms of high-end clean workshops, and coordinating the promotion of safety, quality, progress and other work. In the future, Hefei Lanke will continue to adhere to the responsibility of state-owned enterprises, strictly abide by the safety bottom line, strictly control the quality关口， and fully and efficiently promote the subsequent construction work such as the installation of mechanical and electrical equipment， the decoration of clean workshops， and the commissioning of plant systems， to ensure that the project is delivered and put into production according to the set goals， and provide a solid guarantee for improving the domesticization level of the semiconductor industry chain and strengthening the independent control ability. 

Anhui Jingmi Mask Co., Ltd. was established on March 28, 2025. It was jointly set up by Hefei Jinghe Integrated Circuit Co., Ltd. and several other investors. 

The core member of the team is Cai Guozhi, who serves as the legal representative of the company. Cai Guozhi is also the chairman of Jinghe Integrated, possessing extensive management experience in the semiconductor industry. 

The company's technology is based on the research and development achievements of photomasks by Jihong Integrated since 2022. In 2024, Jihong Integrated successfully produced the first semiconductor photolithography mask in Anhui Province, and achieved mass production in October of the same year. Jiming Mask took over the transfered mask-related technologies for 28nm and above process nodes by Jihong Integrated, covering 24 patents and 73 proprietary technologies, with a technology transfer amount of 277 million yuan. This means that Jiming Mask has held the production-verified technical cards from the very beginning of its existence. 

In July 2025, Anhui Jingmi Mask completed its first round of strategic financing, with a total capital increase of 1.195 billion yuan (mainly used for the construction of the first production line). The main investors included: Jinghe Integrated (with a capital contribution of 200 million yuan, holding 16.67% of the shares), Hefei State-owned Capital Venture Investment Co., Ltd., Hefei Jianxiang Investment Co., Ltd., Hefei High Investment, Highxin Capital (investment of 105 million yuan), Jinghe Huixin Fund, Zhanxing Zhiyuan Capital, Anhui Science and Technology Innovation Investment, Huatai Baoli, Hua An Jiaye, and Keda Silicon Valley, etc. 

This is a typical "chain leader incubation + capital escort" model: Jincheng Integrated Circuit has separated its mature photomask business and jointly raised funds with several state-owned and market-oriented investment platforms to ensure the construction of the production line, laying the foundation for subsequent large-scale expansion.
