The OAI Model 200 Mask Aligner is a cost-effective high performance mask Aligner that has been engineered with industry proven components that have made OAI a leader in the photolithography capital equipment industry. The Model 200 is a bench top mask Aligner that requires minimal cleanroom space. It offers an economic alternative for R&D, or limited scale, pilot production. Utilizing an innovative, air bearing / vacuum chuck leveling system, the substrate is leveled quickly and gently, for parallel photo mask alignment and uniform contact across the wafer during contact exposure. The system is capable of one micron resolution and alignment precision.
