WebIntroducing Optical Lithography Lithography creates a resist image on the wafer. The subsequent etching, lift off, or ion implantation process is masked by the resist image at the areas dictated by the lithography mask. Hence, the thin film material on the wafer is selectively removed, built up, or its characteristics are selectively altered. WebThe LITHOSCALE system integrates full-wafer top-and-backside alignment utilizing dedicated objectives with visible and IR capability and proprietary chuck designs accommodating wafer sizes up to 300 mm. The system features dynamic alignment modes with an automatic focus, in order to adapt to the substrate material and surface variations.
