Latest Patents

Sullivan holds a patent for a "Process for channeling ion beams." This patent describes a method for minimizing ion scattering, which ultimately improves resolution in ion beam lithography. The process involves providing a substrate coated with ion beam resist at a specific distance from an ion beam source. A monocrystalline membrane with a patterned ion absorption region is then positioned between the substrate and the ion beam source. The patterned region can be an ion absorption mask or a pattern of ion-damaged areas within the membrane. Finally, a collimated wide area ion beam is directed through the crystal lattice channels in the membrane, which are exposed by the patterned region. This innovative approach establishes low resistance paths for ion beams, minimizing deflection angles and enhancing the precision of the lithography process.
