Patent number: 10493559Abstract: Laser processing is enhanced by using endpointing or by using a charged particle beam together with a laser. End-pointing uses emissions, such as photons, electrons, ions, or neutral particles, from the substrate to determine when the material under the laser has changed or is about to change. Material removed from the sample can be deflected to avoid deposition onto the laser optics.Type: GrantFiled: July 8, 2009Date of Patent: December 3, 2019Assignee: FEI CompanyInventors: Marcus Straw, David H.

Publication number: 20180298490Abstract: A method of creating a layer of a target deposit-material, in a first target pattern, on a substrate surface. The substrate surface is placed in a vacuum and exposed to a first chemical vapor, having precursor molecules for a seed deposit-material, thereby forming a first substrate surface area that has adsorbed the precursor molecules. Then, a charged particle beam is applied to the first substrate surface area in a second target pattern, largely identical to the first target pattern thereby forming a seed layer in a third target pattern. The seed layer is exposed to a second chemical vapor, having target deposit-material precursor molecules, which are adsorbed onto the seed layer. Finally, a laser beam is applied to the seed layer and neighboring area, thereby forming a target deposit-material layer over and about the seed layer, where exposed to the laser beam.Type: ApplicationFiled: June 20, 2018Publication date: October 18, 2018Applicant: FEI CompanyInventors: Steven Randolph, Marcus Straw

Patent number: 9679741Abstract: An environmental cell for a charged particle beam system allows relative motion between the cell mounted on an X-Y stage and the optical axis of the focusing column, thereby eliminating the need for a sub-stage within the cell. A flexible cell configuration, such as a retractable lid, permits a variety of processes, including beam-induced and thermally-induced processes. Photoelectron yield spectroscopy performed in a charged particle beam system and using gas cascade amplification of the photoelectrons allows analysis of material in the cell and monitoring of processing in the cell. Luminescence analysis can be also performed using a retractable mirror.Type: GrantFiled: November 9, 2010Date of Patent: June 13, 2017Assignee: FEI CompanyInventors: Libor Novak, Marek Uncovsky, Milos Toth, Martin Cafourek, William Parker, Marcus Straw, Mark Emerson

Publication number: 20170002467Abstract: An improved process control for a charged beam system is provided that allows the capability of accurately producing complex two and three dimensional structures from a computer generated model in a material deposition process. The process control actively monitors the material deposition process and makes corrective adjustments as necessary to produce a pattern or structure that is within an acceptable tolerance range with little or no user intervention. The process control includes a data base containing information directed to properties of a specific pattern or structure and uses an algorithm to instruct the beam system during the material deposition process. Feedback through various means such as image recognition, chamber pressure readings, and EDS signal can be used to instruct the system to make automatic system modifications, such as, beam and gas parameters, or other modifications to the pattern during a material deposition run.Type: ApplicationFiled: July 4, 2016Publication date: January 5, 2017Applicant: FEI CompanyInventors: Marcus Straw, Chad Rue, Steven Randolph, Aurelien Philippe Jean Maclou Botman, Clive D.

Publication number: 20160181060Abstract: A method is provided for preparing a sample for correlative optical and electron imaging and correcting aberrations in the imaging process due to sample deformation. Dye-coated fiducial markers are distributed throughout the sample volume. The fiducial markers are preferably in the form of polystyrene nanospheres that are functionalized on their surface and subsequently treated with a fluorescent dye. The dye does not penetrate the sphere but only binds to the surface. By limiting the dye to the surface of the nanospheres, the shape of the spheres can be determined in iPALM and in charged particle images aiding in tracking of physical changes that may occur to the sample volume.Type: ApplicationFiled: December 22, 2014Publication date: June 23, 2016Applicant: FEI CompanyInventors: Steven Randolph, James Miyasaki, Marcus Straw
