摘要:
A repaired laser ablation mask is disclosed capable of withstanding laser fluences in the range from about 200 mJ/cm.sup.2 to at least 500 mJ/cm.sup.2. The repaired mask comprises a single or multiple layers of apertured metal, such as, aluminum, on a quartz substrate. The laser mask repair technique and structure are also disclosed. The thickness of the metal layer, such as, aluminum layer, is in the range from about 2 microns to about 6 microns. A laser projection etching technique is also disclosed for using the repaired ablation mask.
