Photolithography with
Shipley 1813 for 1 micron line resolution
- Spin S1813 at 5000
rpm, 2500 r/s, for 45 seconds -> 1.2 micron (apply HMDS before PR coating,
if necessary)
- Softbake on leveled
hot plate for 75 seconds @ 115C.
- Align wafer using MA6
(Hard Contact, Al. Gap 30 microns)
- Expose (Wavelength @
436nm, intensity @ 20 mW [CI2]) for 4 seconds
- Develop using MF319
for 45 seconds
- Inspect the photoresist
pattern
- Hardbake in oven for
30 minutes @ 120C, if needed.
