In fact, the overall appearance size of the 90 nm process chip is almost the same as the overall appearance of the current 7 nm and 14 nm process chip.
The difference is the number of components arranged on the chip, for example, the 90 nanometer process chip can be photoengraved on 1 billion components, then the 7 nanometer process chip may be arranged on 5 billion components, a very simple problem, then for sure, the 7 nanometer process chip is much more powerful, Because there are many more components on the chip of the 7-nanometer process process, the design is more perfect, more reasonable, and the function is more powerful.
