excimer laser based debonding, namely, line scanning
In line scanning, the naturally rectangular output
distribution of the excimer laser is reshaped into a thin
line, which is focused on to the carrier/adhesive
interface. The length of this laser…
excimer laser is homogenized and reshaped into a long,
thin line typically
having a length that
is equal to the width
(or half the width),
of the panel. This allows the entire panel
to be processed in one (or two, respectively) passes under the laser beam,…
