…The energy density that is required
to initiate the launch of a microLED is only a fraction of the fluence
needed to decompose the GaN for
LLO sapphire removal. This means
that large beam dimensions and
thus very high process speeds can
be achieved. In fact, employing…

Figure 2: Schematic of a LLO process for the delamination of GaN film from sapphire wafer.
The LEDs are processed on the sapphire growth substrate to the level that a temporary or
final carrier substrate is attached. In the subsequent LLO process, the LED wafer is exposed to…
