Ultratech Stepper Electro Magnet Assembly Semiconductor Lithography Part

Ultratech Stepper Electro Magnet Assembly Semiconductor Lithography Part

This is an electro magnet assembly pulled from an Ultratech Stepper semiconductor lithography system. The assembly consists of a cylindrical strong-field magnet housed in a polished aluminum cap, mounted to a black anodized aluminum base plate with an integral bracket and adjustment hardware. A multi-pin plastic connector cable exits the assembly for integration into the stepper system's electrical circuit. A caution label on the magnet housing warns of a strong magnetic field and instructs users to keep floppy disks, computers, and magnetically sensitive items away.

Applications

Ultratech Stepper systems are photolithography tools used in semiconductor wafer fabrication to project circuit patterns onto silicon wafers with high precision. Electro magnet assemblies within these systems are used for precise stage positioning, wafer clamping or leveling, or actuator functions that require controlled magnetic force. Ultratech (formerly Ultratech Semiconductor) produced a widely-used line of step-and-repeat and step-and-scan lithography systems from the 1980s through the 2000s, and components from these systems remain in demand for maintenance and repair of installed tools still running in semiconductor fabs and research facilities. Buyers for this type of part are typically semiconductor equipment engineers, fab maintenance teams, and equipment refurbishers working on Ultratech stepper platforms.
