Title: Innovations of I Roger Oliver
Introduction
I Roger Oliver is a prominent inventor based in San Diego, California. He has made significant contributions to the field of extreme ultraviolet (EUV) light sources, holding a total of 11 patents. His work is crucial for advancements in various technological applications.
Latest Patents
One of his latest patents is for an extreme ultraviolet light source. This invention provides a reliable, high-repetition rate, production line compatible high energy photon source. A very hot plasma containing an active material is produced in a vacuum chamber. The active material is an atomic element having an emission line within a desired extreme ultraviolet (EUV) range. A pulse power source comprising a charging capacitor and a magnetic compression circuit provides electrical pulses with sufficient energy and electrical potential to produce the EUV light at an intermediate focus at rates exceeding 5 Watts. In preferred embodiments designed by the applicants, in-band EUV light energy at the intermediate focus is 45 Watts, extendable to 105.8 Watts.
Another notable patent is an apparatus and method for a plasma produced extreme ultraviolet (EUV) light source multilayer collector. This invention includes a plasma formation chamber and a shell within the chamber in the form of a collector shape having a focus. The shell is designed to carry operating heat away from the multilayer reflector and radiate the heat from the surface of the shell on the side opposite from the focus. The material of the shell may include silicon carbide, silicon, Zerodur or ULE glass, aluminum, beryllium, molybdenum, copper, and nickel. The apparatus may also comprise at least one radiative heater directed at the shell to maintain its steady-state temperature within a selected range of operating temperatures.
