ZEISS AIMS fab neo New System

Mask Qualification

Preventing defects from printing with state-of-the-art mask inspection

Even least defects in the layout of a single photomask can consign all chips on the exposed wafer resulting in enormous losses. That is why it is crucial to inspect all masks for defects, understand their impact on the photolithography process, and eliminate them before the mask is used in a stepper or scanner. The best way to reliably control quality at this stage is to optically emulate the photolithographic process using the Aerial Image Measurement. The AIMS™ system is the only scanner emulator covering all lithography techniques including Double Patterning, Source Mask Optimization (SMO) and Inverse Lithography.
