Semiconductor Manufacturing
The complex industrial process of fabricating integrated circuits and electronic components from semiconductor materials through multiple precise steps including wafer production, photolithography, and packaging.
Semiconductor Manufacturing
Semiconductor manufacturing is one of the most sophisticated and precise industrial processes ever developed, forming the backbone of modern electronic devices production. This multi-stage process transforms raw silicon materials into complex integrated circuits that power our digital world.
Core Manufacturing Steps
1. Wafer Production
- Starting with high-purity silicon crystal ingots
- Slicing into thin wafers (typically 200-300mm diameter)
- Polishing to achieve atomic-level smoothness
- Surface preparation and cleaning
2. Fabrication Process
The main fabrication involves several repeated steps:
Photolithography
