Re: "laboratory" entrepreneur Zong Yanmin
silicon carbide semiconductor is the third generation semiconductor material. If metal materials support the mechanical age, the first generation of semiconductor silicon materials support the information age, then, as the new energy, 5G communications and the basic technology of the Internet of things, SiC will support the age of green and intelligent.
in the application area, it can reduce the volume of the electric vehicle by 44%, the power increase 78%, the endurance of the mileage by 15%; use the LED lamp, run 6 hours a day, can use 45.6 years, energy saving 90%; can reduce the volume of a substation to the size of a suitcase, and can also allow the communication base station coverage to increase. A number of times.
, therefore, in Zong Yanmin's eyes, the new generation of semiconductor technology is a national strategic issue, reflecting the wrestling between big powers. It has been listed as a national strategy by many developed countries successively. In 2014, Obama personally led the establishment of the third generation semiconductor industry alliance, which was introduced into the "prime minister's strategy" by the Japanese government in one year.
however, this field has been controlled and monopolized by developed countries such as the United States, Europe, Japan and so on, and no Chinese enterprises can enter. The US Department of commerce still explicitly implements embargo and technology blockade to China.
stepping into this field, Zong Yanmin and Shandong Tianyue challenge is a worldwide problem.
station "giant shoulders"
how difficult is it to manufacture silicon carbide semiconductors?
"it's the technology of managing atoms." Zong Yan civilian a pile of digital description: carbon and silicon, a "slow", to melt around 3000 degrees, a "active", about 1400 degrees centigrade melting, after melting two to "hand hand" and other proportions to form silicon carbide; it has 220 crystal forms, only one of them can be used as semiconductors, in the process of combination, not The tube arrangement is biased, or the angle is not correct. At the beginning of
, Shandong Tianyue was also faced with the problem of no ready technology. A chance, Zong Yan people learned that the academician of the Chinese Academy of Sciences and Professor Jiang Minhua of Shandong University have succeeded in cultivating silicon carbide single crystal in the laboratory after 10 years' efforts, but they did not realize industrialization until they died in 2011, so they bought the technology. "
" Professor Jiang Minhua is admired that if the advanced results of a lifetime study have been put on the shelf, it is a pity that our country will lose a great opportunity in semiconductor technology again. " Zong Yanmin said.
, however, from the laboratory technology to the industrialization, the difficulty is no less than the breakthrough in the laboratory, especially the silicon carbide semiconductor industrialization, the high technical threshold and the capital investment, many enterprises are in this stage.
Zong Yanmin continues to look for "the shoulders of giants", to integrate the world's top resources in the field of technical subdivision, to set up joint research and development centers in the United States and Germany, and to make more international advanced technologies used for us.
