Hi Gary,

What did you mean 'expose the material properly'?

Sorry to mention that the exposure dose is calculated by multiplying the time
and intensity of 10 mJ/cm2. So, my exposure dose ranged from 70 mJ/cm2 to 100
mJ/cm2.

Please comment either the dose is too low or too high.

Thanks,

Yingtao

Sounds like you did not expose the material properly. Gary
