Twin crystal ingot manufacturing process

Rapid mass production

low cost

Expansion

Only a few companies in the world can sell both N- SiC and SI-SiC wafers at the same time. Shengxin will rank first in Taiwan and top 5 in the world .

Develop materials, configurations, and process technologies with high crystal growth stability, high stability and reproducibility on the same machine; transfer to other machines: reach the standard within 3-5RUN

Close to the manufacturing costs of major international factories, use self-made seed crystals and raw materials, and simultaneously improve the crystal growth rate, the thickness of the ingot, and develop its own crystal growth equipment

From scratch, gradually master the development of largescale crystal expansion technology (thermal field simulati on, material, process) from 2 ” to 6 ” .

3[rd] place supply chain European and American Supply Chain

1. Si SiC in Europe and the US is an important strategic material and is prohibited from being sold to mainland China

2. Due to the US semiconductor trade ban, many European and US chip manufacturers cannot sell many products to the Chinese market

3. Affected by trade bans and Xinjiang issues, products using Chinese raw materials cannot be sold locally in Europe and the US

China Supply Chain

1. China is aware of the seriousness of the stuck neck and actively develops the non-U.S. supply chain 2. End products using Chinamade SiC raw materials cannot be sold to markets outside of China
