Patents by Inventor Alex P. G. Robinson

Alex P. G. Robinson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11746255
    Abstract: Disclosed and claimed herein is a composition for forming a spin-on hard-mask, having a fullerene derivative substituted with an amine and a crosslinking agent. The formulation is drain compatible with other solvents used in the semiconductor industry.
    Type: Grant
    Filed: February 25, 2018
    Date of Patent: September 5, 2023
    Assignee: IRRESISTIBLE MATERIALS LTD
    Inventors: Alex P. G. Robinson, Guy Dawson, Alan G. Brown, Thomas Lada, John Roth, Edward Jackson
  • Publication number: 20230273520
    Abstract: The present disclosure relates to novel negative- working and novel positive-working photoresist compositions for high speed, fine line processing using, for example, ultraviolet radiation, extreme ultraviolet radiation, beyond extreme ultraviolet radiation, X-rays, electron beam and other charged particle rays. The novel photoresists contain specific metals components which are added to positive and negative photoresist compositions which are themselves composed of conventional photoresist materials.

  • Patent number: 11681227
    Abstract: The present disclosure relates to novel negative-type photoresist composition and methods of their use. The disclosure further relates to multiple trigger photoresist processes which allow for the improvement in contrast, resolution, and/or line edges roughness in some systems without giving up sensitivity. The photoresist compositions and the methods of the current disclosure are ideal for fine patent processing using, for example, ultraviolet radiation, extreme ultraviolet radiation, beyond extreme ultraviolet radiation, X-rays and changed particle. The disclosure further relates to sensitivity enhancing materials useful in the disclosed compositions and methods.
