- This photosensitive layer was irradiated with laser under the conditions described above. After exposure, develop with 1.5 wt% Na 2 CO 3 aqueous solution (25 ° C, 1 minute), wash and dry,
- the obtained resist pattern was evaluated. As a result, it was confirmed that a resist resolution of 5 ⁇ m width was obtained between adjacent beam spot irradiation sites!
