Removal of irrelevant information[edit]
on the "Atomic to cellular scale", 10nm reading "As of 2016, the 10 nanometre was the smallest semiconductor device fabrication node" The issue here lies in that the fabrication 'node' does not correspond with physical dimensions of semiconductor, current actual fabrication dimensions are on the order around for example 10-50nm on say Y axis, and 10-20nm on the X axis. I did not remove this part myself for I am not clear if it should be, I think it should be removed but prefer a second opinion so to speak. John2376 (talk) 01:58, 23 November 2023 (UTC)
