Tropel UltraSort
The next generation of automated wafer qualification
The Corning Tropel Ultra Sort represents the state-of-the-art in automated semiconductor wafer measurement, and continues a 25-year tradition of providing metrology solutions to semiconductor manufacturers. Designed specifically for high volume wafer manufacturing, this automated system offers the utmost in rapid, repeatable, accurate non-contact verification of many substrate materials in the field.
The Tropel UltraSort includes cassette-to-cassette handling with user configurable sorting capability. This Class 100-compliant system integrated a grazing incidence interferometer with industry standard robotic wafer handling. It can measure wafer sizes from two to eight inches wide, and is well suited for a wide variety of materials including gallium arsenide, sapphire, quartz, germanium, silicon, and much more.
