The excellent properties of Sic have been playing important roles in Chinese society development and construction. As an accepted "future material" in semiconductor industry, silicon carbide has huge potential.
During electric power producing, delivery and distribution, power transmission efficiency and availability factor are of vital importance. At present, the major material for electric power transmission device is silicon material, whose physical property has been exhausted in three decades. As an accepted "future material" in semiconductor industry, silicon carbide has huge potential.
Sic materials is resistant to high temperature, so if auto production adopts sic materials, revolutionary change will take place. Sic materials can be employed in water-cooling system as cooling fin, whose weight is usually 2 to 4 kilos, costly, large, heavy and hard to control. While Sic materials is resistant to high temperature, previous heavy cooling fin can be reduced substantially, which is a revolutionary change.
Sic also has a wide application in demanding industrial fields for voltage. According to China semiconductor ex-vice president Zhao Zhengping, silicon power device top off voltage can reach 6000V, while that of currently Sic power device can be as high as 200,000V. China Smart Grid construction requires power device whose top off voltage is higher than 10,000V. Single silicon power device cannot meet the requirement while Sic power device is competent.
Besides, Sic plays as a pillar material in green energy development. According to relevant authorities, China has been suffering from resource constraints such as coal and petroleum and energy crisis has become an even greater problem in China. Chinese government has advocated green energy, photovoltaic power generation and wind power generation. Sic power device can improve power transmission efficiency as well as availability factor to relieve energy crisis.
The excellent properties of Sic have been playing important roles in Chinese society development and construction. Meanwhile, Sic has also ushered in broader space for global semiconductor power device industry. Therefore, developing Sic material has become a choice for global semiconductor companies.
