TECHNOLOGY

VLIS is going to be the world's leading process chain for fully processed glass wafers!

SPEED

VLIS can prepare several 10,000 vias per minute!

PRECISION

The VLIS process creates high density through holes with virtually no edge chipping.

About VLIS

VLIS = Volume Laser Induced Structuring

The new VLIS process (short for Volume Laser Induced Structuring) enables high density through holes in glass for advanced packaging solutions. For various applications, tens of thousands of holes per wafer are processed. Our VLIS process enables a very fast manufacturing process with high precision which matches a potential metallization process.
