QDJJ Technology Co., Ltd. is located in Qingdao National High-tech Industrial Development Zone. It is a company specializing in the research, development, production and sales of sapphire wafers for high-efficiency semiconductor substrates.
QDJJ Company uses the independently developed semiconductor substrate wafer processing technology with international advanced level, which is driven by the major requirements of national semiconductor lighting projects, and the industrialization of sapphire wafers to meet the requirements of ultra-high brightness semiconductor substrates is The goal is to build the first large-scale high-quality semiconductor sapphire wafer manufacturing company in China, to produce and process 2-inch and 4-inch high-precision semiconductor sapphire substrate wafers with independent intellectual property rights, which can meet the requirements for patterned substrate production. Jiaxing Jingdian has changed the current situation that domestic sapphire substrates are completely dependent on imports, actively explored the international market, and provided high-quality core basic materials for semiconductor epitaxial companies.
