With a total of 3 patents to his name, Cone's work has had a lasting impact on various industries.

Latest Patents

One of Cone's latest patents is a reregistration system for a charged particle beam exposure system. This innovative system determines and positions the location of a substrate target surface concerning multiple charged particle beams. The technology allows for the simultaneous writing of integrated circuit patterns at various locations on the substrate. Reregistration is achieved by scanning the charged particle beams over fiducial marks on the substrate, which may consist of high atomic number materials or predefined topographical features. The scattered electrons from these marks are detected and converted into electrical signals, enabling precise substrate location determination.

Another significant patent is the glass nozzle array for an inkjet printer. This invention involves a glass nozzle array formed with a series of glass tubes aligned parallel to one another and cemented in epoxy between two glass plates. The process includes aligning small glass tubes on supports of oriented silicon, pouring epoxy resin through the tubes, and curing the assembly to produce wafer-thin glass nozzle arrays. This innovative design enhances the functionality of inkjet printers by providing a reliable orifice plate or charge plate.
