* '''Thickness of resist''': In general, it is recommended to work with an aspect ratio of ~1, i.e. where the width of the pattern is of same size than the thickness of the resist. Furthermore, when you decide for the resist thickness, consider which transfer you need:
* '''Thickness of resist''': In general, it is recommended to work at or below an aspect ratio of ~1, i.e. where the width of the pattern is not smaller than the thickness of the resist. Furthermore, when you decide for the resist thickness, consider which transfer you need:
** For [[Specific_Process_Knowledge/Lithography/LiftOff|lift-off]] processes, we recommend resist thicknnesses ~5 times larger than the thickness of the metal to be lifted.
** For [[Specific_Process_Knowledge/Lithography/LiftOff|lift-off]] processes, we recommend resist thicknnesses ~5 times larger than the thickness of the metal to be lifted.
** For dry or wet etch processes, investigate the resist etch rate of your process as this might limit the minimum thickness of your resist.
