China seems to have figured out how to make 7nm chips despite US sanctions
Chinese semiconductor giant SMIC has reportedly been manufacturing 7-nanometer chips since last year, the best sign yet that China has found a way to develop advanced components despite US efforts to curb the country's homegrown silicon capabilities., which recently bought a cryptocurrency-mining ASIC manufactured by SMIC and found that it uses a 7nm process after doing a study of the chip's die.
The reason for this is crypto-mining ASICs"likely do not feature the typical bitcell memory that true 7nm technology definition requires," so it's more feasible that the chip is mostly a demonstration of 7nm logic. "This is the most advanced technology product TechInsights has seen from SMIC so far and may be leading to a true 7nm process that incorporates scaled logic and memory bitcells," TechInsights said.
The development will likely be received as bad news for the US government, which has been trying to slow down China's ability to manufacture advanced chips over national security concerns. While the 7nm crypto-mining chip is probably meant for consumer or commercial use, the process node will likely end up in military applications in China due to the country's"military-civil fusion"
