The “Nano-Level Polishing” of Chips: How CMP Technology Turns Silicon Wafers into “Mirror Surfaces”?
In semiconductor manufacturing, there is a technology known as “Global Planarization Unique Solution”—it can reduce the roughness of silicon wafer surfaces to the nanometer level, allowing for precise etching of 7nm and 5nm circuits; in computer hard drives, it enables the flying height of the read/write head to be as low as 10nm without scratching … Read more
