ML2 LITHO DEVELOPMENT
Meeting the 3 key targets (resolution, overlay, throughput) for direct write on Si is extremely challenging! Targets are rapidly moving according to Moore’s law. Missing the targeted
insertion node can have major impact on the ROI
Focusing on mask writing as intermediate milestone! Reduces the risk: any throughput improvement is welcome
Both 193nm and EUVL can use this
