Pingmei Shenma silicon carbide semiconductor chip material successfully rolled off the line

On January 4, it was learned from China's Pingmei Shenma Group that the silicon carbide semiconductor chip materials produced by the group - silicon carbide high-purity powder and silicon carbide crystal ingots successfully rolled off the production line, and the product quality reached the domestic first-class level, which not only marked the group's new energy and new materials industry to add a "new army", but also accelerated the filling of the gap in the third-generation semiconductor industry in Henan Province
.

It is understood that the wide bandgap semiconductor material represented by silicon carbide is known as the third generation of semiconductor materials, compared with the traditional first and second generation semiconductor materials, the third generation semiconductor materials are more suitable for manufacturing high-frequency and high-power devices
with high temperature resistance, high voltage resistance and high current resistance 。 The third-generation semiconductor made based on it has many advantages such as wider band gap, higher breakdown electric field, higher thermal conductivity, and stronger radiation resistance, and is widely used in strategic emerging fields such as 5G communication technology, new energy vehicles, solar energy, and national defense industry, and is becoming the new commanding height of the global semiconductor industry and the key
to a new round of scientific and technological revolution.

Focusing on the national strategic needs, last year, China Pingmei Shenma Group invested 70 million yuan to launch the silicon carbide-based semiconductor material demonstration line development project, mainly developing and producing the third generation of semiconductor silicon carbide powder and silicon carbide substrate materials, and creating a "test field"
for the 100-billion-level chip material industry.

During the construction period, the project team overcame difficulties such as tight time, heavy tasks, and repeated epidemics, quickly and orderly promoted the project construction, and built a demonstration production line for silicon carbide-based semiconductor materials in only 67 days, and the purity of silicon carbide powder products reached 99.
99995%, and the quality of silicon carbide crystal ingot products reached the domestic first-class level
.

According to reports, the project gathers the industrial advantages of Pingmei Shenma Group, upstream use of coal, coke oven gas to prepare high-purity hydrogen, needle coke, electronic silicon, molten silicon and other raw material advantages, downstream docking energy storage lithium battery and photovoltaic and other industries, can quickly form the national and even the world's leading "coal-hydrogen-needle coke-high-purity silane-silicon carbide-silicon carbide semiconductor-energy storage lithium battery and photovoltaic" high-quality industrial chain
