The GCA Tropel UltraSort II Flatness Tester is a flatness tester categorized under Test & Probe. The GCA Tropel UltraSort II Flatness Tester accepts 6-inch wafers.[1][2][3]
What it is
How it works
General reference — not yet source-verifiedA flatness test and probe tool measures wafer planarity for semiconductor handling and inspection workflows. A tool in this class typically supports the identification of wafers that meet or fail flatness criteria before later process steps.
A flatness tester in this class generally compares the wafer surface against a reference and records deviation from the desired plane. A probe-oriented flatness tool generally belongs to the metrology and qualification segment of a fab rather than to pattern transfer or film formation.
Where it fits in the process flow
General reference — not yet source-verifiedThe GCA Tropel UltraSort II Flatness fits in wafer qualification and incoming inspection workflows. The tool serves a decision point before wafers move into process steps that require controlled surface geometry.
A flatness tool is generally used upstream of lithography, bonding, or other operations that depend on wafer shape control. The tool supports sorting, screening, and acceptance decisions based on surface flatness.
Applications
The GCA Tropel UltraSort II Flatness is used for wafer flatness testing in semiconductor manufacturing.[3]
