According to reports, SMIC now appears to be supplying bitcoin mining chips made using advanced 7-nanometer technology. According to the report, the new technology is two generations ahead of SMIC's established 14-nanometer semiconductor technology because it allows the fabrication of smaller transistor widths to produce faster and more efficient mining chips. SMIC's Chinese customer, Minerva Semiconductor, currently showcases 7nm chips on its website (without specifying a manufacturer), claiming that mass production will begin in July 2021.
