概要（Overview）

The ADE 9500 UltraGage is a benchmark in wafer geometry characterization, essential in device fabrication and silicon wafer manufacturing. It accurately measures thickness, flatness, bow/warp, and more, using noncontact methods with 10nm resolution, applicable to both patterned and polished wafers. This compact tool offers nondestructive control, with options for manual or cassette operation, and supports optional networking including SECS/GEM. Ideal for applications in photolithography, CMP, and other processes, the UltraGage is a versatile, high-performance metrology solution.
