Photolithography with Shipley 1827 for 1
micron line resolution
- Spin S1827 at 5000 rpm, 2500
r/s, for 30 seconds -> 2.7 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 11 seconds
- Develop using MF319 for 45
seconds
- Inspect the photoresist
pattern
- Hardbake in oven for 30
minutes @ 120C, if needed.
