Introduction. Electron beam lithography (EBL) is a nano-fabrication technique based on the controlled irradiation of a sample covered with a sensitive resist via a focused beam of electrons. EBL is typically performed by a scanning electron microscope (SEM) integrated with a lithographic system for the control of the beam and/or the SEM stage..

A high-resolution nanopatterning technique is desirable with the present rapid development of hydrogel nanodevices. Here, we demonstrate that polyvinyl alcohol (PVA), a popular polymeric hydrogel, can function as the negative-tone resist for electron beam lithography (EBL) with a resolution capability as narrow as 50 nm half-pitch. Electron-beam lithography is promising for future manufacturing technology because it does not suffer from wavelength limits set by light sources. Since single electron-beam lithography systems have a common problem in throughput, a multi-electron-beam lithography (MEBL) system should be a feasible alternative using the concept of massive parallelism. In this paper, we evaluate the advantages.

Electron beam resists are the recording and transfer media for e-beam lithography. The usual resists are polymers dissolved in a liquid solvent. Liquid resist is dropped onto the substrate, which is then spun at 1000 to 6000 rpm to form a coating. After baking out the casting solvent, electron exposure modifies the resist.
