Training for PROLITH lithography simulation software is also available in CULearn:
- Standard SEMI spec wafers ONLY based on current tool configuration
- Carrier wafers MUST be approved by Photolith staff
- Back of substrate must be CLEAN - NO RESIST on back
- Mask must be CLEAN - no resist or fingerprints
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.
- Step and repeat exposure system with laser-controlled stage motion
