Designed for maximum versatility, the OAI Model 500 high-resolution mask alignment and exposure system is a high-performance contact mask aligner developed for ultra-precise, submicron, level-to-level alignment lithography. The Model 500 features a family of interchangeable modular subsystems including a choice of exposure systems with intensity controlling power supplies, mask alignment tooling systems, and alignment optics. The Model 500 is a cost-effective design that enables the user to adapt quickly and easily to changing requirements. Ideal for both standard as well as unique applications, the Model 500 can be configured for a wide range of applications including infrared-based, substrate-to-mask alignment. Exposure systems facilitates quick change between the Near, Mid and Deep UV spectrums. The system can process a wide range of materials including glass and ceramic ranging in substrate size from 5mm to 200mm.

The Model 500 alignment tooling incorporates interchangeable mask/substrate chuck capability, differential micrometer or motorized electronic motions for the X, Y, and Theta axes, and an adjustable electronic clutch for setting substrate-to-mask pressure. This system utilizes a pneumatic load/unload mask assembly, and is available with single or split-field optics. The Series 500 features a processor interface and integrated vibration isolation system. The system may be operated in manual or semiautomatic modes. The laboratory-grade console provides the operator with ample work and storage areas. Unexcelled in long term reliability, versatility and ease of use, the Model 500 Mask Alignment and Exposure System is a powerful tool that combines functionality and low cost of ownership.
