PEC AAO Mold
- Single mold layer thickness +150um
- Gap 4um


AAO: Aluminum Anodic Oxide
PEC AAO Mold
Difference between AAO mold & PR mold
- Vertically wet-etchable material
- Enable precise patterning with 1:40 aspect ratio (compared to conventional PR mold 1:3 ~ 1:4)
- Simplify process via thick single mold layer (~150um)
- Accurate dimension control (±1.5um)
Decrease the length
- Minimize electrical signal distance
- Minimize resistance

Increase the surface area
- Make vertically thicker
- Enable Multi beam with narrow pitch

Precise stacking layer
- Differentiated plating technology
- Layer component and ratio can be modified per customer's requirements
- Achieve high plating U% (< 5%) from entire area
