ABSTRACT:
Antireflective layers (54, 86, and 109) have been developed that have discrete portions (541, 542, 861, 862, 863, 1091, and 1092). The discrete portions (541, 542, 861, 862, 863, 1091, and 1092) allow the antireflective layers (54, 86, and 109) to be used in many instances where using a single layer of uniform composition would be difficult or impossible. Alternatively, a single antireflective layer with a continuously graded composition can be used.
