Abstract
In some embodiments, the present disclosure relates to an integrated chip fabrication device. The device includes a stealth laser apparatus arranged over a chuck configured to hold a substrate. An infrared camera is arranged over the chuck and configured to detect an alignment mark below the substrate. The alignment mark is used to align the stealth laser apparatus over the chuck. Control circuitry is configured to operate the stealth laser apparatus to form a stealth damage region at a location within the substrate that is determined based upon the alignment mark. The stealth damage region separates an inner region of the substrate from an outer region of the substrate.
