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. WebAn approach is presented for nanoscale patterning of zinc oxide (ZnO) using electron beam (e-beam) lithography for future nanoelectronic devices and for hard lithographic masks. Zinc acetate (Zn 4 O (CH 3 COO) 6) films were exposed using a scanning electron microscope (SEM), causing decomposition of Zn 4 O (CH 3 COO) 6 into ZnO. high caffeinated coffee
