WebFig.1 E-beam Lithography machine diagram Fig.2 Electron gun diagram There are several advantages of using e-beam lithography over photolithography and x-ray lithography. The most important advantage is the resolution of the critical dimension. The resolution, using photolithography, is limited due to diffraction. WebGenerally and depending on the equipment, the increment is by 5°C or by 1°C. Beware that the temperature precision is directly relied to this. To bake your SU-8 photoresist strongly prefer an increment by 1°C. Almost all photolithography hot-plates provide 1°C temperature precision so it should not be a problem when buying the hotplate.
