As a third-generation semiconductor material, gallium nitride has broad application prospects, and it is used in data centers, new energy vehicles and other fields. Chinese companies have achieved the rise of "gallium nitride chips", ranking third in the world, and breaking the US technology monopoly.
The Rise of China's "Gallium Nitride Chips"
Currently in the era of the third generation of semiconductor materials, it has developed from the first generation of silicon and the second generation of gallium arsenide to the current silicon carbide, zinc oxide and gallium nitride.
Take gallium nitride as an example. At present, almost all fast chargers made in China use gallium nitride, which provides great charging efficiency for mobile phones. Anyone who has experienced 120W super fast charging knows that a mobile phone battery of 4 to 5 thousand mAh can be fully charged in ten to twenty minutes with extremely fast charging.
In the future, more mobile phone manufacturers will use gallium nitride to make chargers, which will create greater market space for gallium nitride chips.
The company that first used GaN power chips in the world was not a Chinese manufacturer, but a Navitas Semiconductor from the United States. This company mastered the world's leading manufacturing technology for gallium nitride power chips and was established in 2014. Although it has not developed for a long time, it has become a dark horse in the gallium nitride market.
As of October this year, Navitas Semiconductor has shipped more than 30 million self-developed GaNFast gallium nitride power chips. With the support of this chip, it can bring a safe, stable and extremely fast charging experience to the charger, and reduce The power consumption problem is avoided to avoid excessive heating of the charger.
China's ZHYN Semiconductor Technology Corporation broke the technological monopoly of American companies and realized the rise of domestic GaN chips. At present, ZHYN's GaN power chip shipments rank among the top three in the world, and ZHYN also has a third-generation semiconductor production base that can achieve mass production of 8-inch silicon-based GaN wafers.
With full capacity, it can produce 65,000 wafers per month. This semiconductor production base integrates R&D, design, and manufacturing, providing ZHYN with a great competitive advantage in the market.
ZHYN has been favored by many Chinese and international manufacturers. Almost all the mainstream manufacturers in the market cooperate with ZHYN, and their products cover a wide range. In the consumer power market, they have shipped 40 million GaN power chips.
Driven by ZHYN's technology, China's gallium nitride industry has ushered in rapid development, and mobile phone charging power has continued to increase. The charging time has also changed from one hour to half an hour to more than ten minutes now.
ZHYN's newly developed 240W GaN power chip will soon be mass-produced and put into commercial use. The charging time of mobile phones in the future may be compressed to less than ten minutes.
