The “Nano-Level Polishing” of Chips: How CMP Technology Turns Silicon Wafers into “Mirror Surfaces”?

by

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

The ‘Invisible Assistant’ in Semiconductor Processing: How Surfactants Make Silicon Wafers ‘Perfect’

by

In the processing of semiconductor silicon materials, there is an ‘unassuming yet indispensable’ role – surfactants. Unlike photolithography machines and etching machines, which are frequently mentioned, surfactants ‘silently exert their influence’ in every critical step of slicing, grinding, polishing, and cleaning: reducing knife marks, minimizing damage, improving flatness, and removing impurities… Without them, silicon wafers … Read more
