The semiconductor industry is one of the most critical industries in the entire electronic information industry chain. It provides critical basic materials for the integrated chip industry, LED industry, and photovoltaic industry, and has a huge impact on the entire electronic information industry. In the middle of the last century, the invention of monocrystalline silicon and semiconductor transistors and the successful development of silicon integrated circuits led to the third technological revolution. The invention of quartz optical fiber materials and GaAs lasers in the early 1970s promoted the rapid advancement of optical fiber communication technology. The development and gradual formation of high-tech industries has enabled humanity to enter the information age.
Semiconductor products are widely used in the electronics and microelectronic industries to produce a variety of precision original devices such as transistors, integrated circuits, and solid-state lasers.
According to senior experts in the industry, semiconductor materials can be roughly divided into three generations. The first generation of semiconductors is silicon; the second generation of semiconductors is represented by gallium arsenide; the third generation of semiconductors is represented by gallium nitride, which has outstanding performance in the conversion of electricity and light, and is more efficient in transmitting microwave signals. Therefore, it can be widely applied to various fields such as lighting, display, and communication.
Nowadays, under the prevailing trend of LED, GaN has made a major breakthrough in the LED lighting industry as a semiconductor light-emitting diode, which has greatly boosted the consumption of metal gallium. Current LED gallium nitride chips are typically based on sapphire or silicon carbide substrate wafers. Such a substrate LED chip has a great defect. If a gallium nitride wafer is used as a substrate, the heat dissipation problem during illumination can be effectively solved, and the brightness per unit area can be increased by 10 times. Nobel Prize in Physics 2014 Nakamura said that GaN on GaN LED technology will replace the existing first-generation LED technology into the mainstream of LED development in the near future, and GaN substrate will become the final choice of LED industry. bottom. As the price of GaN wafers declines year by year, GaN substrates will not be available in the semiconductor lighting application market, and the consumption of GaN will increase exponentially.
In addition to LED lighting, electronic optoelectronic devices are another major application market. Currently, gallium nitride (GaN) is becoming the mainstream process technology for semiconductor RF power devices. It is widely used in some military applications and microwave communications. According to a report released by the US Strategic Analysis section, demand for GaN is enhanced by the market for early warning, surveillance, and fire control radar.
A head of North American strategic analysis department said in the 2013-2023 GaN development trend, the relevant semiconductor and other device market will rise from 1.2 billion to 2.1 billion during the 10-year period, of which GaN The technology is maturing, with a compound growth rate of 26.4%, which is used in all radar systems.
Gallium nitride is the material system with the highest electrooptic and photoelectric conversion efficiency to date, and can be a key basic material for preparing wide-spectrum, high-power, high-efficiency microelectronics, power electronics, optoelectronics and other devices. The future of semiconductors belongs to gallium nitride, and the prospect of gallium nitride is bright.
Gallium nitride is made of rare metal gallium and nitrogen. China is the world's largest producer of metal gallium. The annual output of metal gallium exceeds 300 tons/year, but China's metal gallium industry is large but not strong. A large amount of metal gallium is exported as a primary product. According to customs data, China's exports of metal gallium exceeded 100 tons in the first ten months of this year, but prices have been falling. Some gallium producers continue to lose money.
As the world's largest rare metal exchange, the Pan-Asian Nonferrous Metals Exchange has already launched a spot trading of metal gallium, which will greatly promote the healthy development of China's metal gallium industry and help China obtain the pricing power of metal gallium.
