ABSTRACT:
A process for manufacturing a semiconductor device comprises the step of annealing a porous passivation layer which is deposited on the surface of the device and which covers metallization layers fabricated thereon, by irradiating a laser beam on the passivation layer so as to densify the passivation layer, while the laser beam scans the surface of the passivation layer.
