Mask Flatness Measurement System
Tropel® UltraFlatTM 200 Mask System - Corning Inc. (Corning)
The Tropel® UltraFlatTM 200 Mask System was designed specifically for the photomask industry. It delivers the lowest measurement uncertainty for ever-tightening mask flatness specifications. Shrinking device features require not only flatter wafers, but flatter masks.
