In the LED industry, China's self-innovated silicon substrate LED technology is known as the third technological route besides silicon carbide (SiC) LED technology and sapphire substrate LED technology. It breaks the firm patent barriers formed by LED manufacturers in Japan, Europe and the United States, and owns completely independent intellectual property rights, allowing it to go abroad freely.

Difficult! This is the first reaction of anyone who knows about LED technology to growing LED material on a silicon substrate. What's so hard about that? Prior to 2004, more than 30 years of research had not solved the thermal and lattice mismatches of silicon substrates and gallium nitride materials, and high-quality gallium nitride luminescent films could not be obtained.

Good! Silicon substrate LED technology route is the LED industry has been dreaming of technology route for decades. What's so good about it? If we can break through the silicon substrate LED technology problem and achieve large-scale mass production, we can greatly reduce the cost and accelerate the arrival of LED lighting era!

Silicon substrate LED technology route is the LED industry's dream technology route, but because of the technical difficulty, so most of them stay in the laboratory testing stage. It was not until 2004, in a humble laboratory at Nanchang University, that silicon substrate LED blue light chip first emerged. The silicon substrate LED technology achieved a revolutionary breakthrough and marked an epoch-making milestone in the history of LED in the world.
