Tabletop Front & Backside Mask Aligner

Model 200IR - OAI

The OAI Model 200IR Mask Aligner is a tabletop system that requires minimal clean room space. It is a cost-effective 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 Model 200IR Mask Aligner is capable of one micron resolution and alignment precision. It has an alignment module which features mask insert sets and quick-change wafer chucks that enable the use of a variety of substrates and masks without requiring tools for reconfiguration. The alignment module incorporates micrometers for X, Y, and z-axis.
