Paper Abstract

For high density optical disk mastering processes, it is important to appropriately select the light source and optical layout as well as to optimize photoresist and exposure method. A g-line type photoresist is preferred for use in the mastering processes, compared with i-line type photoresist. By using the UV light source, the pit width is narrowed down to 0.25 micrometers , which is easily fabricated. Under preferred fabrication exposure power for cross talk and modulation amplitude, excellent jitter values, 8/8 ns, 10.8 ns and 16.9 ns were achieved for quadrupled, quintupled and 6-times density CD-ROMs.
