  • 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%
