Resist patterning on wafers using e-beam lithography is an alternative to optical lithography. Especially for rapid prototyping applications with very small wafer volume, electron beam direct write (EBDW) has certain advantages. druthers clifton park reviewsWebSep 3, 2013 · The authors present an improved method for direct patterning on free-standing, dielectric membranes using electron-beam (e-beam) lithography. The method is based on an advanced etchmask that both reduces charging and allows for tuning of the etch mask thickness to support high aspect ratios even for small structures. druthers brewing company schenectady ny

"WebAll subtractive (etch-based) e-beam lithography processes have to contend with the fact that the most common and easily-used positive e-beam resist (PMMA) is a notoriously bad etch mask. Resists with better etch resistance than PMMA exist (ZEP520, for example) but can be prohibitively expensive. " - E beam and hard mask
