| Zusammenfassung: | Methods and systems for forming slots in a substrate that has opposing first and second surfaces. The method makes a laser cut through either the first or second surface of the substrate sufficient to form a first trench. Material is also removed through the other of the first and second surfaces effective to form, in combination with the laser cut, a slot. At least a portion of the slot passes entirely through the substrate, and the slot has an aspect ratio greater than or equal to 1. |
