Geely Auto announced the mass production of 7nm automobile SoC semiconductor "SE1000" starting next year. SE1000 is China's first in-house developed 7nm SoC semiconductor for cars and it will help increase China's self-sufficiency in the semiconductor sector.
SE1000 is developed by Geely's subsidiary Hubei Si Engine Technology with 87 layers of circuits and 8.8 billion transistors in an area of 83 square millimeters, conforming with AEC-Q100 standards. Si Engine's general director of product planning Chiang Han-ping said at the Smart Geely 2025 conference that the future of high-performance smart cockpit is 7nm semiconductors.
In comparison with 16nm chips, 7nm has 3.3 times gate density and generates 35-40% higher speed, and reduces 65% of energy expenditures. Production costs will go lower as production capacity and quality yields rise. SE1000 will first be used in Geely's automobiles before other Chinese OEMs could apply the chip in the designing process of new models. They are expected to complete assembly and tests in 2022.
China is the largest car market in the world with less than 10% of the domestic semiconductor supply. Si Engine said it aims to increase self-sufficiency in the semiconductor sector in the future. Horizon, China's unicorn chipmaker, is also working with carmakers on developing semiconductors.
