This projection printer uses a DUV (248nm) lens column (0.63 N.A.) to provide a 4:1 reduction with an exposure field size up to 22mm square. Minimum feature size is <0.20µm. The number and placement of the dies is programmable. Wafer sizes of 3" up to 200mm can be accommodated, and pieces with significant effort. Registered alignment is typically <0.045µm, even when using backside alignment. 6" x 0.250"-thick quartz masks are used.
