Webgeneration lithography is SCALPEL® (SCattering with Angular Limitation Projection Electron-beam Lithography).2,3 SCALPEL is a reduction image projection technique which uses 100 keV electrons and scattering contrast. The use of electrons circumvents the limitation of diffraction in optical lithography. The principle is illustrated in Fig. 2 ... WebThe NA of optical lithography tools ranges from about 0.5 to 0.6 today. Thus, the typical rule of thumb is that the smallest features that can be printed are about equal to the wave-length of the light used. Historically, the improvements in IC lithography resolution have been driven by decreases in
