- GaAs: Uniform clearing
- InP: Uniform clearing
- InAs: Uniform clearing
- Si: Optimal contrast
Note
Base dose does not change with resist thickness, developing time does. However, if the developing time is fixed, say to 60s, a thinner layer of resist will need lower "base dose", since it's being over developed.
Experimental
125 kV:
InP: 607 uC/cm2 and phi = 35%
InAs:
Si: 906 uC/cm2 and phi = 45%
GaAs:752 uC/cm2 and phi = 39%
