The chip is a pinnacle of human technology, embodying vast amounts of wisdom. The chip supply chain is extremely complex; spending a hundred million may buy a luxury apartment, but it may not necessarily support a chip from design to mass production. This is especially true for chips that use advanced processes, where the costs … Read more
Source: WeChat Official Account “Chip Theory” Introduction: Integrated circuits (chips) are manufactured layer by layer using photolithography technology. Therefore, the concept of “layers” exists in chip technology. So, how many concepts of “layers” are there in chip technology? Media reports say that Micron has launched a 176-layer 3D NAND flash memory chip; what does “layer” … Read more
