In accordance with the "Environmental Impact Assessment Law of the People's Republic of China" and the "Measures for Public Participation in Environmental Impact Assessment" and other relevant regulations, the environmental impact assessment information of Jiangsu Huaxing Laser Technology Co., LTD. 's gallium arsenide and indium phospide semiconductor epitaxial wafer production process upgrading and renovation project is hereby made public for the second time.

I. Basic Project Information

1. Project Name

The project of upgrading and upgrading the production process of gallium arsenide and indium phosphide semiconductor epitaxial wafers of Jiangsu Huaxing Laser Technology Co., LTD.

2. Project Overview

Construction Entity: Jiangsu Huaxing Laser Technology Co., LTD.

Construction location: North side of Liaohe West Road and west side of Huashan North Road, Economic Development Zone, Pizhou City (relying on the existing factory area for construction);

Construction nature: Technological transformation;

Project investment: The total investment of the project is 100 million yuan.

Construction content and scale Utilizing the existing 5,000 square meters of factory buildings, over 10 sets of equipment such as metal-organic chemical vapor deposition systems, purifiers, and tail gas treatment systems were phased out. Additionally, more than 20 sets of equipment including metal-organic chemical vapor deposition systems, contact lithography machines, magnetron sputtering, electron beam evaporation, nanoimprint, and purifiers were purchased and installed. Upgrade and renovate the existing production line. After the transformation is completed, the annual production capacity of gallium arsenide semiconductor epitaxial wafers will be 50,000 pieces and indium phosphide epitaxial wafers 10,000 pieces.

Ii. Key Points of the Environmental Impact Assessment Conclusion:

The project of upgrading and upgrading the production process of gallium arsenide and indium phosphide semiconductor epitaxial wafers of Jiangsu Huaxing Laser Technology Co., Ltd. complies with the requirements of relevant industrial policies. The site selection conforms to the relevant planning requirements. During the production process, the concept of clean production is followed. The various pollution prevention and control measures adopted are technically feasible and economically reasonable, which can ensure the long-term stable and compliant discharge of all kinds of pollutants. The prediction results show that the pollutants discharged by the project have a relatively small impact on the surrounding environment and environmental protection targets, and the impact on the regional environment is acceptable. After taking targeted risk prevention measures and implementing emergency response plans, environmental risks are controllable.
