Lithography dof
WebIn electron-beam lithography you have a limited selection of resists. The positive resists PMMA and ZEP are polymers that are broken up by electron irradiation. After exposure, the smaller bits dissolve faster in the “developer”. This is a very simple contrast mechanism; there isn’t any complex chemistry as you find in photoresist. http://www.chipmanufacturing.org/h-nd-85.html
