In-Depth Analysis of Semiconductor Sub Fab: Functions, Composition, and Design Considerations

Semiconductor manufacturing is one of the most complex and precise fields in the contemporary industrial system, with the wafer fabrication plant (Fab) being its core carrier. Within the Fab, the Sub Fab (support facilities) does not directly participate in wafer processing but is crucial for ensuring the entire manufacturing process operates efficiently, stably, and safely. … Read more

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 “Nano-Level Polishing” of Chips: How CMP Smooths Multi-Layer Circuits?

by

In chip manufacturing, there is an “invisible hero”—without it, multi-layer metal circuits would resemble “uneven mountain roads,” making precise lithography impossible, and achieving 7nm or 5nm processes would be a fantasy. This hero isChemical Mechanical Polishing (CMP), which can control the surface undulations of silicon wafers within 50Å (0.005μm), achieving true “global flattening.” Today, we … Read more
