3D Ice Lithography (3DIL) is an advanced, direct-write, additive manufacturing technique used to create complex, high-resolution 3D micro- and nanostructures. Using an electron beam, a vaporized precursor, that is frozen onto a cooled substrate, is cross-linked or decomposed in a sequential manner. The printing typically takes place in a scanning electron microscope.
The process comprises

  1. Gas injection and icing on a cryogenic substrate,

  2. Direct writing into the iced resist via e-beam exposure,

  3. Repetition of icing and writing for layered build up of the intended 3D structure,

  4. Development by evaporation of unexposed resist.
