Prototype of Massively Parallel Electron Beam Write (MPEBW) system was developed for mask less lithography. A 100×100 array of nanocrystalline-silicon (nc-Si) electron emitter is controlled by an active matrix driving LSI. The LSI receives external writing bitmap data, and switches 100×100 electron beamlets on/off. The operation of the LSI was confirmed and 1/100 reduction electron optic system using the active matrix emitter array was fabricated. A 17×17 nc-Si emitter array was assembled with a 1:1 exposure test system and driven by commercially available display driver LSIs. The active matrix electron beam (EB) exposure was confirmed.
