Laser Ablation

Laser scribing offers several advantages when compared to lane definition by slot die printing, including, among others:

1. - Better aesthetical fill factor by reducing the width of the landing zone of the interconnect.
2. - Simplification of the coating process since no special alignment between coated layers is required (single lane coating)
3. - Higher geometrical fill factor due to elimination of one insulator and the possibility of digital alignment of individual structures with respect to insulator.
4. - Yield improvement due to lower de-wetting and miss-alignment problems between layers.
5. - Design flexibility due to digital patterning (no need of custom tooling like shims)
