The 110 °C hotplate is used for 2 different things; hard bake of resist, and image reversal baking between two exposures. It is recommended to hard bake for 2 min. For image reversal it is recommended to bake at least 100 sec., some bake for 120 sec. | The 110 °C hotplate is used for 2 different things; hard bake of resist, and image reversal baking between two exposures.
