Pavel Poloucek 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: 11017980
    Abstract: The invention relates to a method of manipulating a sample in an evacuated chamber of a charged particle apparatus, the method performed in said evacuated chamber, the method including: providing a sample on a first substrate; bringing an extremal end of a manipulator in contact with the sample; attaching the sample to said extremal end, the attaching being a removable attaching; lifting the sample attached to the extremal end of the manipulator from the first substrate and transport the sample to a second substrate; attaching the sample to the second substrate; and detaching the sample from the extremal end of the manipulator. At least one of the steps of attaching the sample being performed solely by bringing the sample into contact with a bundle of carbon nanotubes.

  • Publication number: 20180053638
    Abstract: A plasma generator is located outside the vacuum chamber and generates neutral reactive particles and charged particles. A magnet positioned outside the plasma generator deflects the charged particles, preventing some or all of them from entering the vacuum chamber, thereby preventing secondary plasma sources from forming in the vacuum chamber, while allowing neutral reactive particles to enter the vacuum chamber to reduce contamination. Associated methods are also described.

  • Patent number: 9741527
    Abstract: A specimen holder for a Charged Particle Microscope is disclosed. The holder has a support structure with an elongated member including a specimen mounting zone. The specimen mounting zone comprises a rotor with an axis perpendicular to the elongated member with a paddle connected to it which may be rotated. Specimens may be mounted on the paddle so that rotation of the paddle allows specimens to be rotated and/or inverted for microscopic observation on both sides. Specimens may either be directly mounted on the paddle, or on a grid, half-moon grid, lift-out grid, aperture frame, dielectric film, etc.

  • Publication number: 20160181059
    Abstract: A specimen holder for a Charged Particle Microscope, comprising: A support structure; An elongated member, a first end of which is connected to said support structure and the second end of which comprises a specimen mounting zone, the member having a longitudinal axis that extends along its length between said first and second ends, wherein said specimen mounting zone comprises: A rotor that is rotatable about a transverse axis extending substantially perpendicular to said longitudinal axis; A paddle connected to said rotor so as to be rotatable about said transverse axis, the paddle comprising a specimen mounting area; Driving means connected to said rotor, which can be invoked to rotate said paddle through a rotational range that allows the paddle to be inverted relative to an initial orientation thereof.
