It was actively promoted by Qingdao Merchants Bureau. On the morning of April 8, the sapphire wafer processing project with a total investment of 2.5 billion yuan was held in Qingdao High-tech Zone. This is the first enterprise to start production after the completion of Qingdao High-tech Zone.
This project combines the advanced sapphire wafer processing technology of Silicon Valley in the United States with China's manufacturing cost advantage to form a competitive advantage of excellent cost performance. The long-term goal is to build a LED industry chain with sapphire wafer processing as the entry point. The initial investment of the project is 140 million yuan. After the completion of the project, it will produce 150,000 pieces of sapphire wafers per month, which will fill the gap in the domestic market, replace imports, and gradually expand production capacity.
Substrate wafers are the key basic materials for the semiconductor lighting industry. Among them, sapphire substrate wafers are the most widely used substrate wafers for blue and white LEDs due to their mature technology, good quality and excellent cost performance. They account for global blue and white light. 90% of the amount of LED chips.
After the project's entire industrial chain matures, the project will generate 10 billion yuan in sales revenue and tax revenue of more than 1.5 billion yuan, making Qingdao one of the national semiconductor wafer processing centers and the national semiconductor lighting industrialization base.
