AI Overview
UV laser drilling of silicon wafers utilizes high-energy, ultraviolet (UV) pulsed lasers to create precise micro-holes and cuts with minimal thermal damage or material chipping. Commonly used in semiconductor fabrication, it is ideal for micro-machining, dicing, and drilling, offering superior precision for holes as small as a few microns.
Key Advantages of UV Laser Drilling
- Minimal Thermal Affect: UV lasers enable "cold ablation," which minimizes heat-affected zones, reduces cracking, and results in smooth, clean edges on silicon.
