The smaller field of electron beam writing makes for very slow pattern generation compared with photolithography (the current standard) because more exposure fields must be scanned to form the final pattern area (≤mm 2 for electron beam vs. ≥40 mm 2 for an optical mask projection scanner). The stage moves in between field scans.
