Silicon crystals and nanometers are different things and cannot be compared together.
Silicon crystal refers to silicon wafer, is silicon monomer polymerization into a rod after cutting processing, is the basic material for manufacturing chips. And the word nano refers to a physical unit of length, a unit of measurement. A nanometer is about 60,000th the length of the cross section of a human hair, generally in the chip industry refers to the chip process, which is the gate width of silicon transistors. One is the material of manufacturing the chip, and the other is the process of manufacturing the chip.
Silicon crystals are the raw material for making semiconductors and integrated circuits, and nanometers are units of length, so there is no comparison between them, so there is no good
