1 nanometer chip can not be expected for the time to market.
At present, the world's most high-end chip process is 4 nm, for Mediatek's Tianguet 9000 and Qualcomm Snapdragon 8 mobile platforms, respectively, TSMC and Samsung OEM. And the 3-nanometer chip has been rolled and is being prepared for mass production. However, with the current lithography technology, it is close to the limit of the lithography machine, after all, the light source is 13.5 nm, even if it has the ability to do 1 nm, the high cost is not affordable for commercial chips, so 1 nm chips can not be listed at present.
