Abstract
Laser annealing of a-Si to form p-Si LCD panels requires precise control of the annealing beam shape and scan overlap. Three methods are presented for determining the annealed quality of a-Si LCD panels. The first tests the laser beam directly by using polymer coated 8 X 10 inch SensorCards. The second allows live viewing of the beam in real time with a fluorescent glass. The third looks directly at the optical properties of the annealed a-Si to infer eventual electrical properties.
