  • 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.
