Latest Patents

Wolf holds a patent for "Contrast enhancement of electron beam alignment marks." This innovative patent utilizes high atomic number metals or compounds as electron beam registration alignment marks on low atomic number substrates. The combination of these materials results in enhanced secondary and backscattered electron video signals compared to topographical alignment marks made of homogeneous materials. To further augment the enhanced signal contrast, pairs of alignment marks are placed very close together, specifically less than or equal to 3 micrometers apart. The gap between these pairs produces an augmented, enhanced signal contrast. Notably, the backscattered electron signal is significantly enhanced when detected with an energy-sensitive collector, such as a silicon diode detector.
