Large-area and low-power laser stripping method for GaN-base epitaxial layer
A method for stripping large-area GaN-based epitaxial layer by low-power laser features that the pulse laser beam is used to scan the GaN-loased epitaxial film grown on the sapphire substrate from outside to inside while the sapphire substrate is heated and the laser threshold is biased.
